Why Do You Gain Weight During Your Period?

Why do you gain weight during the period? The menstrual cycle is a complex process that involves various hormonal changes in a woman’s body. It typically lasts around 28 days, although this can vary from woman to woman. One of the common symptoms experienced during this time is weight gain. However, it is essential to understand that weight gain during your period is temporary and primarily caused by hormonal fluctuations.

During the menstrual cycle, the levels of estrogen and progesterone in the body rise and fall. These hormonal changes can affect your metabolism, water retention, and appetite, leading to weight gain. Estrogen, in particular, plays a crucial role in regulating body weight. It influences the distribution of fat in the body and can contribute to increased abdominal fat during the premenstrual phase.

10 Common Causes of Weight Gain During Period

Several factors can contribute to weight gain during the period.

1. Hormonal Changes

One of the primary reasons for weight gain during your period is hormonal changes.

Estrogen, progesterone, and insulin are among the hormones that influence metabolism, fat storage, and appetite. Estrogen, for instance, helps to maintain a healthy body weight by regulating the distribution of fat in the body. It promotes the storage of fat in the hips and thighs, which is considered healthier than storing it in the abdominal region.

Progesterone, on the other hand, can increase appetite and lead to cravings for high-calorie foods. This can contribute to weight gain during the menstrual cycle. Insulin, the hormone responsible for regulating blood sugar levels, can also influence weight gain. Women with insulin resistance may be more prone to experiencing weight fluctuations during their period.

2. Water Retention

Water retention is a significant contributor to the weight gain you experience during your period. Hormonal fluctuations can cause your body to retain more water, leading to swollen and bloated feelings. This extra water weight can add a few pounds to the scale.

3. Increased Appetite

Many women experience increased appetite and cravings before and during their period. You might find yourself reaching for comfort foods, which are often high in salt, sugar, and carbohydrates. These extra calories can contribute to weight gain.

4. Reduced Physical Activity

Period-related discomfort, such as cramps and fatigue, can make you less inclined to engage in physical activity. This reduction in exercise can lead to weight gain over time, especially if coupled with increased calorie intake.

5. Emotional Eating

Emotional changes are common during your menstrual cycle. Mood swings, irritability, and stress can lead to emotional eating as a way to cope with these feelings. Indulging in comfort foods can result in additional calorie consumption.

6. Metabolic Changes

Your metabolism can also be affected during your period. Some women experience a slight decrease in metabolic rate, which can lead to weight gain if dietary habits remain the same. It’s essential to be mindful of your calorie intake during this time.

7. Constipation

Hormonal fluctuations can slow down digestion, leading to constipation for some women. This can cause a feeling of fullness and bloating, contributing to temporary weight gain.

8. Muscle Soreness

Cramps and muscle soreness are common during menstruation. These discomforts can deter you from engaging in physical activities and exercising, leading to weight gain over time.

9. Stress

Stress can exacerbate period-related weight gain. The body’s response to stress includes the release of cortisol, which can increase appetite and lead to overeating. Managing stress is crucial in preventing excessive weight gain.

10. Medications

Some medications, such as birth control or hormone therapy, can affect your body’s water balance and metabolism. Be aware of the potential side effects of any medications you’re taking that may contribute to weight gain during your period.

Treatment for Weight Gain During Period

Balanced Diet

Maintaining a well-balanced diet is key to managing weight gain during your period.

1. Fiber-Rich Foods

Include plenty of fiber-rich foods like whole grains, fruits, and vegetables in your diet. Fiber helps you feel full and satisfied, reducing the likelihood of overeating. Whole grains like oats and brown rice are excellent choices.

2. Lean Proteins

Opt for lean sources of protein such as skinless poultry, fish, tofu, and legumes. Protein not only helps stabilize blood sugar levels but also promotes a feeling of fullness, which can curb your cravings.

3. Healthy Fats

Incorporate healthy fats like avocados, nuts, and olive oil into your meals. These fats provide satiety and support hormonal balance. Omega-3 fatty acids found in fatty fish like salmon are particularly beneficial.

4. Limit Processed Foods

Minimize your consumption of processed foods, sugary snacks, and high-sodium items. These can lead to bloating and exacerbate weight gain. Read food labels to avoid hidden sugars and excess salt.


Staying properly hydrated can help reduce water retention, a common culprit of period-related weight gain.

1. Water

Aim to drink at least eight glasses of water daily. Staying hydrated can also help control cravings and prevent overeating.

2. Herbal Teas

Herbal teas like dandelion tea and peppermint tea have diuretic properties that can assist in reducing bloating and water retention.

Regular Exercise

Engaging in regular physical activity can be highly effective in preventing and managing weight gain during your period.

1. Cardiovascular Workouts

Activities like jogging, cycling, and swimming can help burn excess calories and alleviate bloating. Aim for at least 30 minutes of moderate-intensity cardio most days of the week.

2. Strength Training

Building lean muscle through strength training can boost your metabolism, making it easier to maintain a healthy weight. Include resistance exercises like weight lifting or bodyweight exercises.

3. Yoga and Stretching

Yoga can relieve menstrual discomfort and reduce stress, which can contribute to weight gain. Gentle yoga poses and stretching exercises can ease muscle tension and promote relaxation.

Stress Management

Stress can exacerbate weight gain during your period.

1. Deep Breathing

Take slow, deep breaths to calm your nervous system and reduce stress hormones. Deep breathing exercises can be done anywhere, anytime to manage stress.

2. Meditation

Regular meditation sessions can help you stay centered and reduce emotional eating. Guided meditation apps and videos can assist you in getting started.

3. Mindfulness

Practice mindfulness by focusing on the present moment and being aware of your body’s signals of hunger and fullness. Mindful eating can help you make healthier food choices.

Herbal Remedies

Certain herbs may help alleviate period symptoms, including weight gain.

1. Ginger

Ginger has anti-inflammatory properties and can reduce bloating and inflammation. You can make ginger tea or add fresh ginger to your meals.

2. Chamomile

Chamomile tea has calming properties that can ease mood swings and reduce stress-related weight gain. Sip on chamomile tea during your period to promote relaxation.

When to see a doctor?

Here are some signs that might indicate you should see a doctor:

  • Rapid and Unexplained Weight Gain: If you gain a significant amount of weight quickly during your period or any other time in your cycle, it’s a cause for concern.
  • Severe Bloating: While some bloating is normal during menstruation, if you experience severe and uncomfortable bloating that is accompanied by weight gain, it may be worth seeking medical advice.
  • Changes in Urination: If you notice changes in your urination patterns, such as increased frequency or difficulty urinating, it could be a sign of an issue like urinary tract infection (UTI) or kidney problems.
  • Persistent Pain: If you have severe abdominal or pelvic pain accompanying the weight gain, it could indicate an underlying condition like endometriosis or fibroids.
  • Other Unusual Symptoms: If you experience other unusual symptoms alongside weight gain, such as extreme fatigue, irregular periods, heavy bleeding, or changes in bowel habits, these may also warrant a visit to the doctor.
