Image Credits: AI Generated Vitamin D is commonly known as ‘Sunshine Vitamin” but it’s role extends far beyond maintaining healthy bones. It functions more like a hormone than a traditional vitamin, influencing several systems in the body, including the immune system , metabolism, reproductive health and hormone regulation. Why Is Vitamin D Important? Vitamin D is best known for keeping bones strong, but it also plays an important role in women's health throughout life. Vitamin D receptors are found in the ovaries, uterus, uterine lining, and placenta, allowing it to influence several reproductive and metabolic processes. Maintaining healthy Vitamin D levels supports overall well-being, hormonal balance, and bone health. Vitamin D And Reproductive Health Vitamin D plays an important role in female reproductive health by supporting normal ovarian function, follicle development, hormone production, and ovulation. It also helps improve insulin sensitivity and reduce inflammation, both of which are important for healthy reproductive function. Adequate Vitamin D levels may support fertility and contribute to normal menstrual and reproductive health. Vitamin D And Irregular Periods Irregular periods can occur due to stress, hormonal imbalances, thyroid disorders, weight changes, PCOS, or nutritional deficiencies. Studies have shown that women with low Vitamin D levels are more likely to experience irregular menstrual cycles. Also read: Irregular Periods: Causes, Symptoms And Treatment Vitamin D And PCOS Vitamin D deficiency is common in women with PCOS. Research suggests that maintaining adequate Vitamin D levels may: Improve insulin sensitivity Reduce insulin resistance Support regular ovulation Improve menstrual regularity Reduce inflammation Support overall metabolic health While Vitamin D is not a treatment for PCOS on its own, it can be an important part of comprehensive PCOS management. Also read: PCOS: Diagnosis And Treatment Vitamin D And Menopause As women reach menopause, falling estrogen levels increase the risk of bone loss and osteoporosis. Vitamin D is essential for helping the body absorb calcium, maintain strong bones, and support muscle function, reducing the risk of falls and fractures. Maintaining healthy Vitamin D levels, together with adequate calcium intake, regular weight-bearing exercise, and a healthy lifestyle, supports healthy ageing and overall well-being. Vitamin D: Myth Vs. Fact Myth 1: Vitamin D Is Only Important For Strong Bones  Fact: Vitamin D is well known for supporting calcium absorption and bone health, but vitamin D receptors are also present in many cells and tissues. Vitamin D is involved in immune function, muscle function and several processes within the body  Source: NIH Office of Dietary Supplements Myth 2: Taking More Vitamin D Gives Better Results  Fact: More is not always better. Taking excessive amounts of vitamin D can cause calcium to build up in the blood, a condition known as hypercalcaemia. High doses should only be taken under medical guidance. Source: NIH Office of Dietary Supplements Myth 3: Vitamin D Alone Can Treat PCOS  Fact: Vitamin D may support insulin sensitivity, menstrual regularity and metabolic health, particularly when a deficiency is present. However, it is not a standalone treatment for PCOS. PCOS management may also include lifestyle changes, medicines and regular medical care. Source: The Role of Vitamin D Oral Supplementation in Insulin Resistance in Women with PCOS Myth 4: Every Irregular Period Is Caused By Vitamin D Deficiency Fact: Low vitamin D levels have been associated with irregular menstrual cycles in some studies. However, irregular periods can also be caused by stress, PCOS, thyroid conditions, weight changes, medicines and several other factors.  Source: Lower plasma 25-hydroxyvitamin D is associated with irregular menstrual cycles Myth 5: Everyone Needs Regular Vitamin D Testing Fact: Routine vitamin D testing may not be necessary for every healthy person. A healthcare professional may recommend a test based on a person's symptoms, medical history, risk factors or current treatment. Source: Endocrine Society Guideline Here are some facts about how vitamin D is absorbed, activated, and used by the body: 1. Your Liver And Kidneys Help Activate Vitamin D: Whether you get Vitamin D from sunlight, food or supplements, it first travels to the liver and then to the kidneys , where it is converted into it’s active form.  Source: Holick MF. (2007). Vitamin D Deficiency. N Engl J Med. 357:266–281. doi:10.1056/NEJMra070553  2. Take Vitamin D With Your Largest Meal:  Vitamin D is a fat-soluble vitamin, so taking it with a largest meal of the day that contains healthy fats improves absorption compared with taking it on an empty stomach. Source: Mulligan GB, Licata A. (2010). Taking vitamin D with the largest meal improves absorption. J Bone Miner Res. 25(4):928–930.   3. Vitamin D Works Like a Hormone, Not Just a Vitamin: The active form of vitamin D binds to the vitamin D receptor inside cells and helps regulate the activity of numerous genes. Through this mechanism, vitamin D supports bone health and contributes to immune function, cell growth and differentiation. Source: Carlberg C, Campbell MJ. (2013). Vitamin D receptor signaling mechanisms: Integrated actions of a well-defined transcription factor. Steroids, 78(2), 127–136. doi: 10.1016/j.steroids.2012.10.019. 4. Body Fat Can ‘Store Away’ Vitamin D: Vitamin D is stored in fat tissue. In people with higher body fat, more vitamin D may become trapped in these stores, leaving less available in the bloodstream. This is one reason obesity is associated with lower circulating vitamin D levels.  Source: Wortsman J et al. (2000). Decreased bioavailability of vitamin D in obesity. Am J Clin Nutr. 72(3):690–693. 5. Exposure To Sunlight Is Non-Negotiable During Supplementation:  Though the ideal time for vitamin D production is midday, regular and sensible sunlight exposure can support the body’s natural vitamin D levels. Source: Holick MF. (2004). Sunlight and Vitamin D for Bone Health and Prevention of Autoimmune Diseases, Cancers, and Cardiovascular Disease. Am J Clin Nutr. 80(Suppl):1678S–1688S.  6. More Is Not Always Better—Avoid Self-Prescription: Vitamin D can be toxic at extremely high intake levels. Published cases of vitamin D toxicity with hypercalcaemia, where both the vitamin D dose and blood concentration were known, involved daily intakes of 40,000 IU or more. Source: Vieth R. (1999). Vitamin D Supplementation, 25-Hydroxyvitamin D Concentrations, and Safety. American Journal of Clinical Nutrition, 69(5), 842–856. Quick Vitamin D Checklist Use this checklist as a quick reference for maintaining healthy vitamin D levels: Include natural or fortified sources of vitamin D in your diet.  Foods containing vitamin D may include fatty fish, egg yolks and fortified milk, cereals or plant-based drinks.  Get regular and sensible sunlight exposure while avoiding sunburn.  Take vitamin D supplements only in the recommended or prescribed dose.  Take vitamin D with a meal, preferably one that contains some healthy fat, to support absorption.  Check the labels of multivitamins and other supplements to avoid unknowingly taking too much vitamin D.  Inform your doctor about any medicines or supplements you are already taking.  Complete vitamin D blood tests or follow-up tests when advised by a healthcare professional.  Consult a healthcare professional if irregular periods continue, become unusually heavy or stop unexpectedly. Vitamin D can be obtained through sunlight, food and supplements. Because it is fat-soluble, taking it with a meal or snack containing some fat can improve absorption. Source: NIH Office of Dietary Supplements Common Mistakes To Avoid 1. Taking High Doses Without Medical Advice - Avoid a high dose just for faster results — the right amount depends on your age, health, diet and current vitamin D levels. 2. Taking More Than One Supplement Containing Vitamin D - Multivitamins, calcium supplements and vitamin D tablets can overlap. Check labels so you don't take more than recommended. 3. Depending Only On Supplements -  Supplements shouldn't replace a balanced diet, sensible sunlight or medical care — vitamin D can come from all three. 4. Expecting Vitamin D To Fix Every Menstrual Concern -  It may support menstrual wellness, but irregular periods have many causes. Don't delay medical advice while relying only on supplements. 5. Taking Vitamin D On An Empty Stomach - Vitamin D is fat-soluble, take it with a meal containing some fat for better absorption. 6. Ignoring Possible Medicine Interactions - Vitamin D can interact with certain medicines. Tell your doctor or pharmacist what else you're taking before starting it. 7. Continuing A High Dose Longer Than Advised - A doctor may prescribe a higher dose short-term for a deficiency, don't continue it longer than advised. The NIH advises checking supplement amounts carefully because excessive vitamin D can cause harmful calcium levels. It also notes that vitamin D supplements may interact with certain medicines. Frequently Asked Questions 1. Can vitamin D deficiency cause irregular periods? Low vitamin D levels have been associated with irregular menstrual cycles in some women. However, irregular periods can also have other causes, including PCOS, thyroid disorders, stress and weight changes. 2. Does vitamin D help with PCOS? Vitamin D may support insulin sensitivity, menstrual regularity and metabolic health, especially when a deficiency is present. It is not a standalone treatment for PCOS. 3. What is the best time to take vitamin D? Vitamin D can be taken at a convenient time, preferably with a meal. The cited study found improved absorption when it was taken with the largest meal of the day. 4. Can vitamin D help during menopause? Vitamin D supports calcium absorption, bone strength and muscle function, which are especially important during and after menopause. 5. Can too much vitamin D be harmful? Yes. Extremely high doses taken for long periods can lead to vitamin D toxicity and excessive calcium levels in the blood. High-dose supplements should be taken only under medical guidance.

Image Credits: AI Generated PCOD, now increasingly referred to as PMOS (Polyendocrine Metabolic Ovarian Syndrome), is a complex metabolic and hormonal condition that affects multiple systems within the body. PMOS is commonly associated with insulin resistance, weight gain, irregular menstrual cycles, acne, fertility challenges, and hormonal imbalances. While medical management plays an important role, lifestyle modifications remain the cornerstone of long-term symptom management and improved health outcomes.A balanced diet, combined with healthy lifestyle practices, can significantly improve insulinsensitivity, support hormonal balance, regulate menstrual cycles, and enhance overall well-being. However, managing PMOS is not about following extreme diets or chasing quick fixes. Instead, it requires building sustainable habits that support the body's natural healing processes. Managing PMOS: Start With The Basics When a condition affects multiple hormonal and metabolic pathways, the foundations of health become even more important. One practical and sustainable framework for managing PMOS is the 5S Approach: Sleep Hygiene Sunlight Exposure Stress Management Sustainable Diet Serving Size Awareness Together, these five pillars can help improve metabolic health, reduce inflammation, regulate hormones, and support long-term weight management. 1. Sleep Hygiene: The Foundation Of Hormonal Health Sleep is often overlooked, yet it is one of the most powerful tools for hormone regulation. Poor sleep quality can negatively affect insulin sensitivity, appetite-regulating hormones, metabolism, and cortisol levels. Over time, inadequate sleep may worsen many symptoms associated with PMOS. Prioritizing consistent, uninterrupted sleep allows the body to recover, repair, and maintain hormonal balance. What The Research Says A 2025 review found that women with PCOS are more likely to experience sleep disturbances and disrupted body clock rhythms, which may affect hormonal and metabolic health. Source: Circadian rhythm disruption and polycystic ovary syndrome: a systematic review and meta-analysis Practical Tips For Better Sleep Try to go to bed and wake up at approximately the same time every day. Consistency helps regulate the body's internal clock. Avoid screen exposure for at least one hour before bedtime. The blue light emitted from phones, tablets, and computers suppresses melatonin production and overstimulates the brain when it should be preparing for rest. Schedule physical activity earlier in the day whenever possible. Late-night workouts can increase alertness and interfere with sleep quality in some individuals. Avoid daytime sleeping as much as possible. If necessary, limit naps to 20–30 minutes to prevent disruption of nighttime sleep. Create a sleep-friendly environment by dimming lights, reducing noise, and maintaining a comfortable room temperature. Use your bed primarily for sleep rather than work, studying, or entertainment. This helps the brain develop a stronger association between the bedroom and rest. 2. Sunlight Exposure: Harnessing The Power Of Vitamin D Vitamin D, often referred to as the "sunshine vitamin," plays a crucial role in hormonal regulation, immune function, insulin sensitivity, and metabolic health. Research has consistently shown that Vitamin D deficiency is common among women with PMOS and PCOS. While supplementation may be necessary in some cases, regular sunlight exposure remains a simple and effective way to support healthy Vitamin D levels. What The Research Says Studies have found that Vitamin D deficiency is common in women with PCOS and may contribute to some of the metabolic and hormonal changes associated with the condition. Source: Vitamin D and Polycystic Ovary Syndrome (PCOS): A Review Practical Tips For Increasing Sunlight Exposure Aim for at least 20–30 minutes of sunlight exposure daily whenever possible. Avoid overcomplicating sunlight timing. Consistency is often more important than chasing the "perfect" hour of the day. If your schedule is busy, consider moving your workstation closer to a window for part of the day. Take phone or voice calls while walking outdoors instead of remaining seated indoors. Plan outdoor activities with family members whenever possible. Both children and adults benefit from increased physical activity and sunlight exposure. Combine sunlight exposure with light exercise such as walking, stretching, or gardening to maximize overall health benefits. 3. Stress Management: Protecting Your Hormonal Balance Chronic stress can significantly affect hormonal health. Elevated stress levels increase cortisol production, which may contribute to insulin resistance, weight gain, irregular menstrual cycles, and worsening PMOS symptoms. Managing stress is therefore not merely about mental wellness—it is an essential component of metabolic and hormonal health. What The Research Says Research suggests that stress is an important part of PCOS and may influence both metabolic and emotional health. Experts note that metabolic stress, in particular, may contribute to many of the hormonal, reproductive, and psychological challenges associated with the condition. Source: Stress and Polycystic Ovary Syndrome: A Narrative Review Practical Tips For Managing Stress Recognize that there is no universal stress-management technique. Some individuals benefit from meditation, while others find relief through cooking, reading, running, yoga, music, or creative hobbies. Incorporate some form of regular physical activity into your routine. Exercise improves blood circulation, boosts mood, and enhances the body's ability to cope with stress. Learn to identify and differentiate genuine stressors from imagined or exaggerated concerns. Focus on practical coping strategies and problem-solving rather than excessive overthinking or rumination. Prioritize balanced meals at regular intervals. Stable blood sugar levels can help regulate cortisol and support emotional stability. Set realistic expectations and practice self-compassion throughout your health journey. Remember, managing stress is not about eliminating challenges; it is about developing healthier responses to them. 4. Sustainable Diet: The Key To Long-Term Success One of the biggest mistakes many individuals make when managing PMOS is adopting highly restrictive or crash diets. While these approaches may produce temporary weight loss, they are often difficult to maintain and can negatively affect metabolism, energy levels, and overall health. A sustainable, balanced eating pattern is far more effective for long-term symptom management. What The Research Says Research suggests that a balanced eating pattern rich in fibre, protein, healthy fats, and low glycemic carbohydrates may help support insulin sensitivity, weight management, and overall metabolic health in women with PCOS. Source: Nutritional Management of PCOS: Evidence Based Dietary Recommendations Practical Tips For Building A Sustainable Diet Avoid fad diets and quick-fix solutions commonly promoted on social media. Start with a balanced meal plan that includes all major food groups rather than eliminating entire categories of food. Focus on consistency rather than perfection. Small improvements maintained over time produce better results than short periods of extreme restriction. Include a variety of nutrient-dense foods to ensure adequate intake of vitamins, minerals, and antioxidants. Prioritize high-quality protein sources, fibre-rich foods, healthy fats, and complex carbohydrates. Consider adopting an earlier eating window if it suits your lifestyle and medical needs. Stay adequately hydrated throughout the day. Components Of A Balanced PMOS Plate A balanced meal should ideally contain: Complex Carbohydrates Whole grains, Millets, Brown rice, Oats, Quinoa Protein Sources Eggs, Fish, Meat/Chicken, Paneer, Tofu, Lentils and Legumes Fibre Rich Foods Vegetables, Salads, Fruits, Whole grains Healthy Fats Nuts, Seeds, Avocados, Olive oil, Nut butters Each of these nutrients plays a unique role in improving insulin sensitivity, promoting satiety, and supporting hormonal health. 5. Serving Size Awareness: Small Changes, Big Results Even healthy foods can contribute to weight gain and metabolic challenges when consumed in excessive quantities. Developing awareness of portion sizes helps improve blood sugar control and supports sustainable weight management. The goal is not to obsessively count calories or weigh every meal, but rather to build a practical understanding of balanced eating. Practical Tips For Portion Control Visualize a balanced plate regardless of where you are eating—whether at home, a restaurant, a buffet, or a social gathering. Start with a meal composition of approximately 1:1:1 for carbohydrates, protein, and fibre. Eat slowly and chew food thoroughly to improve digestion and satiety. As your eating habits improve, gradually shift toward a 1:2:2 ratio of carbohydrates, protein, and fibre. Understand that occasional indulgences are not the cause of health issues. Long-term dietary patterns matter far more than a single dessert or celebratory meal. Avoid an all-or-nothing mindset. Consistency is more valuable than dietary perfection. Focus on eating balanced meals most days rather than striving for flawless nutrition. Final Thoughts Managing PMOS does not require extreme restrictions, expensive supplements, or unsustainable lifestyle changes. Instead, success lies in strengthening the foundations of health through the 5S Approach: Sleep, Sunlight, Stress Management, Sustainable Diet, and Serving Size Awareness. These habits may seem simple, but when practiced consistently, they can significantly improve insulin sensitivity, support hormonal balance, regulate menstrual cycles, enhance energy levels, and promote overall well-being. Remember that progress in hormonal health is often gradual. Sustainable changes may take time to show visible results, but they are far more effective and safer than quick-fix solutions. By focusing on consistency and building healthy habits one step at a time, many of the symptoms associated with hormonal imbalance can be effectively managed and improved. Frequently Asked Questions 1. Can lifestyle changes really help manage PMOS symptoms? Yes. While medical treatment may be necessary for some individuals, lifestyle habits play a significant role in managing PMOS. Consistent attention to sleep, stress management, balanced nutrition, sunlight exposure, and portion awareness can support metabolic health and help improve overall well-being over time. 2. What foods should I avoid if I have PMOS? Rather than focusing on strict food restrictions, it is often more helpful to reduce reliance on highly processed foods and habits that are difficult to sustain long term. Building meals around whole foods, fibre, protein, healthy fats, and complex carbohydrates can support better nutritional balance and make healthy eating easier to maintain. 3. Is weight loss necessary for managing PMOS? The primary goal of PMOS management is improving hormonal and metabolic health, not simply losing weight. Sustainable lifestyle habits can provide benefits beyond weight management, including improved energy levels, better blood sugar regulation, and overall health. Progress should be measured by long-term health improvements rather than the scale alone. 4. How long does it take to see results from diet and lifestyle changes? Lifestyle changes tend to work gradually rather than producing immediate results. Improvements often depend on factors such as consistency, individual health status, and existing habits. Building sustainable routines and maintaining them over time is generally more effective than seeking rapid changes through extreme approaches. 5. Can stress make PMOS symptoms worse? Chronic stress can affect multiple systems within the body and may influence hormonal and metabolic health. Because of this, stress management is considered an important part of a holistic PMOS management plan. Finding healthy ways to cope with daily stress can support both physical and emotional well-being.

Image Credits: AI Generated Premenstrual syndrome (PMS) symptoms can begin as early as a week before menstruation and may continue for a day or two after the period starts. However, the type, intensity and duration of the symptoms can vary significantly from one person to another.  A common question is: Are there any superfoods that can help with all PMS symptoms? Unfortunately, the answer is NO. PMS is a complex condition with a wide range of symptoms and no single food or set of superfoods can address every symptom effectively.  PMS Symptoms: Emotional And Physical Categories To better understand how nutrition can help, it is important to first categorise PMS symptoms into two broad groups – Emotional and Physical symptoms. The distinction allows for more targeted dietary strategies based on the specific challenges and individual experiences.  1. Common Emotional Symptoms: Mood swings, irritability or anger  Anxiety or feeling tense Sadness or low mood Difficulty concentrating/brain fog 2. Common Physical Symptoms: Bloating  Headaches or migraines Fatigue or low energy Acne breakouts  Constipation  Rather than simply accepting these symptoms, let us look at some possible reasons behind them and the research evidence that may help explain them. Period Comfort Matters Too While food and lifestyle habits may help support overall wellbeing during your cycle, comfort during your period is equally important. Adira Period Panties are designed as a backup layer to help protect against leaks and stains when used with a pad, giving you added confidence during school, work, travel and everyday activities. Understanding Common Emotional PMS Symptoms 1. Mood Swings, Irritability And Anger This is one of the most common premenstrual symptoms experienced by girls and women. Rapid changes in emotions can occur with feelings shifting from happiness to sadness, frustration and irritability. Small inconveniences may feel more overwhelming. Leading to stronger emotional reactions.  Possible Causes:  Irregular meal timing may contribute to mood swings and irritability through the disruption of glucose homeostasis, increased physiological stress responses and circadian rhythm disturbances. Regular meal skipping can lead to blood sugar fluctuations and increased cortisol responses, both of which are associated with irritability, emotional instability, fatigue and stress.  What The Research Says: Circadian Rhythm entrainment factors and premenstrual syndrome : a cross sectional study of the roles of light exposure, exercise and meal timing (BMC women’s Health, 2026) examined meal timing as a circadian regulating factor associated with PMS severity. The study supports investigating meal timing as a contributor to PMS symptoms, including emotional symptoms.  Source: Circadian rhythm entrainment factors and premenstrual syndrome: a cross-sectional study of the roles of light exposure, exercise, and meal timing What Can You Do? As much as possible eat balanced meals not just periods but throughout the month. Out of 21 meals in a week, eat atleast 17-18 balanced meals.  2. Anxiety Or Feeling Tense  Some women experience heightened worry, nervousness, or a sense of unease during the premenstrual phase. This can be accompanied by restlessness, difficulty relaxing or feeling overwhelmed by everyday tasks.  Possible Causes: Delayed meals may increase anxiety and tension by prolonging periods of low glucose availability and activating stress response pathways, particularly during the premenstrual phase when emotional regulation is already more vulnerable. Research on meal skipping and delayed eating suggests that prolonged gaps between meals may increase cortisol secretion and perceived stress, potentially contributing to anxiety symptoms.  What The Research Says: The 2026 BMC women’s Health study identified meal timing as one of the circadian entrainment factors associated with PMS severity, providing a mechanistic framework linking delayed eating patterns with emotional symptoms.  Source: Circadian rhythm entrainment factors and premenstrual syndrome: a cross-sectional study of the roles of light exposure, exercise, and meal timing What Can You Do? As much as possible, try to eat your meals on time, especially a week before your periods. 3. Sadness Or Low Mood Feeling of sadness, tearfulness or emotional sensitivity are common premenstrual symptoms. These mood changes are usually temporary and improve once menstruation begins.  Possible Causes: Lower levels of physical activity throughout the month may contribute to sadness and depressed mood in PMS through reduced endorphin release, impaired stress regulation and decreased psychological resilience.  What The Research Says: Meta-analysis (2020) Exercise for Premenstrual Syndrome: A Systematic Review and Meta-analysis of Randomized Controlled Trials found that exercise interventions reduced psychological, physical, and behavioral PMS symptoms. Source: Exercise for premenstrual syndrome: a systematic review and meta-analysis of randomised controlled trials What Can You Do? As much as possible try to have some level of physical activity throughout the month. Consistency is more important than intensity.  4. Difficulty Concentrating/Brain Fog  Many women report trouble focusing, remembering details, or staying mentally sharp before their periods. Tasks that normally feel easy may require more effort and attention during this time.  Possible Causes: Late night eating may contribute to concentration difficulties and perceived brain fog through circadian misalignment, poor sleep quality, metabolic dysregulation and altered gut brain communication. The emerging field of chrononutrition suggests that meal timing influences circadian rhythms, cognition and metabolic regulation. Studies of time restricted eating have reported improvements in cognitive acuity when eating is aligned earlier in the day.  What The Research Says: Large meals eaten during late night worsened cognitive performance. Participants showed slower reaction times, more attention lapses, poorer memory task performance and greater sleepiness.  Source: Altering meal timing to improve cognitive performance during simulated nightshifts What Can You Do? As much as possible finish your main meals as early as possible. One can always have a snack when hungry at night.  Understanding Common Physical PMS Symptoms 1. Bloating  Hormonal changes can cause the body to retain more fluid, leading to a feeling of fullness or swelling. This may result in temporary weight fluctuations and discomfort around the abdomen.  Possible Causes: Premenstrual bloating may arise from gastrointestinal dysregulation, altered gut motility, visceral hypersensitivity and hormone mediated changes in digestive function rather than fluid retention alone.  What The Research Says: "Mood Symptoms and Gut Function Across the Menstrual Cycle in Individuals with PMS" (Hormones & Behavior, 2024) This study found that gastrointestinal symptoms were significantly more common during the luteal phase and correlated with PMS-related symptoms.  Source: Mood symptoms and gut function across the menstrual cycle in individuals with PMS What Can You Do? After a meal, try to eat digestives like fennel/saunf or drink warm water with ginger slices. These digestives help in reducing bloating.  2. Headaches / Migraines Hormonal shifts can trigger headaches or worsen existing migraine symptoms in some women. These headaches often occur in the days before menstruation and may improve once hormone levels stabilize. Possible Causes: Dehydration may contribute to PMS-related headaches and migraines by reducing plasma volume, altering cerebral blood flow, and increasing susceptibility to migraine triggers. Evidence supports dehydration as a modifiable risk factor rather than the sole cause of migraine symptoms. What The Research Says: Hydration-related migraine studies consistently identify dehydration as a common trigger for headaches and migraine attacks, although it is usually one of several contributing factors. Association of Drinking Water and Migraine Headache Severity (2020) Journal of Clinical Neuroscience. Source: Association of drinking water and migraine headache severity  What Can You Do?  If you are prone to migraines around your periods, try to consciously increase water consumption or eat your water by including more watery fruits and vegetables.  Also Read: Curious about period-friendly beverages? Read our guide on Green Tea For Periods: Is It Beneficial Or Harmful? 3. Fatigue / Low Energy Many women feel unusually tired, sluggish or less motivated during the premenstrual phase.  Changes in hormone levels, sleep quality and physical discomfort can contribute to reduced energy.  Possible Causes: Fatigue during menstrual cycle may be exacerbated by iron deficiency anemia, which reduces oxygen delivery to tissues and impairs cellular energy production. Women with heavy menstrual bleeding are particularly vulnerable.  What The Research Says: Iron deficiency anemia is one of the most well established causes of fatigue, reduced physical performance and low energy levels in menstruating women.  Source: An Overview of Iron Deficiency Anemia What Can You Do? Concentrate on iron rich food sources in your meals throughout the month. If levels are very low, consult a doctor for an iron supplement. 4. Acne Breakouts Hormonal fluctuations can increase oil production in the skin, leading to pimples or acne flareups. Breakouts commonly appear on the face, chin, jawline, chest or back before menstruation.  Possible Causes: Premenstrual acne is primarily driven by hormonal fluctuations that increase sebum production, alter follicular keratinization and promote inflammatory pathways in the skin.  What The Research Says: Hormonal acne is strongly linked to fluctuations in androgen activity and sebaceous gland stimulation. Premenstrual acne flare-ups are a classic example of hormonally driven skin changes. Source: Role of hormones in acne vulgaris What Can You Do? As much as possible, minimise fried foods and increase consumption of fibre at all meals. 5. Constipation  Changes in hormone levels can affect digestion and alter bowel habits around the menstrual cycle. Some women experience constipation, while others may notice loose stools or more frequent bowel movements. Possible Causes: Rising progesterone levels may slow intestinal movement, causing stools to become harder and less frequent, often accompanied by bloating and abdominal discomfort.  What The Research Says: Research has shown that gastrointestinal symptoms, including constipation, commonly occur before and during menstruation in otherwise healthy women.  Source: Gastrointestinal symptoms before and during menses in healthy women What Can You Do? As much as possible, minimise processed foods and eat balanced meals with focus on all components like carbohydrates, protein and fibre. Chew your food well.  Final Thoughts PMS symptoms can be uncomfortable, but small daily habits may make a difference. There is no single food that can prevent all PMS symptoms. Eating balanced meals, staying active, drinking enough water and getting good sleep may help you feel better. Understanding your symptoms is the first step toward managing them more effectively. Frequently Asked Questions (FAQs) About PMS 1. What foods should I eat before my period? Focus on balanced meals that include carbohydrates, protein, fibre, fruits and vegetables. Regular meal timing may also be important for managing PMS symptoms. 2. Why do I feel more emotional before my period? Hormonal changes combined with factors such as sleep quality, meal timing, stress and physical activity may influence mood regulation during the premenstrual phase. 3. Why do I get bloated before my period? Hormonal changes can affect digestion, gut motility and fluid balance, leading to bloating and abdominal discomfort. 4. Is brain fog before a period normal? Many women report difficulty concentrating, forgetfulness and reduced mental clarity before menstruation. These symptoms are commonly referred to as "brain fog." 5. Can dehydration make PMS headaches worse? Research suggests dehydration can act as a trigger for headaches and migraines, making adequate hydration important during the premenstrual phase. 6. Why am I so tired before my period? Hormonal changes, poor sleep quality and iron deficiency can all contribute to fatigue and low energy before menstruation. 7. Does exercise really help PMS symptoms? Research suggests regular physical activity may reduce both emotional and physical PMS symptoms by improving mood, stress regulation and overall wellbeing. 8. Can PMS cause constipation? Yes. Rising progesterone levels before menstruation can slow intestinal movement, making constipation more common during this phase. 9. Is there a single superfood that cures PMS? No. PMS involves multiple biological processes and symptoms. No single food has been proven to prevent or treat all PMS symptoms.
