Aunt Rose (periods) always brings a real basket of goodies when she visits females monthly. Even after facing all-stabbing abdominal pain, mood swing games, body aches, and so on, women sometimes get another PMS (premenstrual symptoms) gift in the form of “weight gain.” Whether you feel just a little bloated or your new pair of jeans fit too tight during your time of the month, weight gain during periods happens to lots of people. Though suddenly sizing up your jeans can be disturbing, period weight gain isn’t anything to be ashamed of. 

Always remember: Bodies change all the time, and your weight is not the first measurement of health.

So, to better understand this, let’s learn why period weight gain happens, what to expect, and how to manage the monthly shift.

Is Weight Gain During Periods Normal? 

Menstrual or period symptoms vary from female to female. Some females breathe through life without a care in the world, while a few are bedbound, wondering if they crossed Satan and got cursed with cramps.

According to a study, approximately 96% of women experience PMS symptoms, and the rest experience period-related swelling in the legs. Gaining weight during your period is perfectly normal. During their periods, women’s body weight can fluctuate by up to 2-3 kg without affecting their health. But if you have gained more than 3 kg or you keep rapidly gaining weight once your menstrual cycle is over, consider consulting your doctor.  

Reasons For Weight Gain During Periods

Here are a few reasons why those numbers on the scale seem to inch up during your period. 

Weight Gain During Periods: Reasons

1. Water Retention

Water retention is one of the leading causes of weight gain in females during the menstrual cycle. This occurs due to hormonal fluctuations during periods. After ovulation, the levels of progesterone and estrogen fall, which is the symptom that you are due for your period. The presence of these two hormones regulates the water balance in your body. When tissue fluid accumulates in your lower abdomen, you start to feel heavy or gain weight.

In this case, you can feel water retention or heaviness in your breasts or stomach. This increases the water percentage in a female body, which causes weight gain. 

 2. Disturbed Digestion

The improper hormonal balance slows down gut functions and impairs the digestion process. Several times, fluctuating estrogen and progesterone hormones increase gas retention in the stomach, causing bloating. Also, many females experience stomach cramps before and during their periods due to the secretion of prostaglandins (hormones) that initiate uterus contraction. Several studies have found that these symptoms increase rectal sensitivity, and females experienced them frequently during their periods. 

3. Skip Workouts

Many females tend to skip their daily workouts when they are on their periods. This happens because when your body enters a bleeding phase and you are not feeling your best, your brain and body become slow and idle. That’s the reason many women either skip their workout sessions completely or perform workouts without putting in real effort. As a result, females gain water weight and start storing fat.

Instead of completely avoiding exercise, it is preferable to practice simple yoga asanas or breathing exercises to ensure adequate oxygen supply to your muscles and thus alleviate menstrual cramps.

4. Gut Problems

During periods, many women face gut problems like indigestion, constipation, and bloating. This is caused by an increase in progesterone levels just a few days before your period, which slows down gut movement. The entire digestive tract of the female body becomes very slow and causes constipation. To avoid this constipation issue, you can include yoga for constipation, especially these days. It will help you feel relaxed and light. 

5. Food Cravings

At this time of the month, many women have cravings for food, and overeating can also be another reason for weight gain. Various different studies believe that fluctuating hormones and serotonin levels during a woman’s cycle are to blame. During periods, hormonal changes can cause a drop in blood sugar levels, which also leads to sugar cravings.

6. Mood Swings

Mood swings during periods are the most common symptoms among women. Also, mood swings and food cravings are often linked with each other. The hormonal changes in the female body make them crave salty and sugary foods. All these snacks and sugary foods are not healthy enough to maintain your weight.

These are the six major reasons for female weight gain during periods. However, there are some other symptoms accompanying weight gain during periods.

Symptoms In Addition To Weight Gain During Periods

Weight gain during periods is temporary and characterized by swollen hands and feet, bloating, and tender breasts. All these symptoms are accompanied by the following symptoms that are also normal during your periods: 

  • Anxiety or depression
  • Irregular Sleeping Patterns
  • Crying spells or angry outbursts
  • Confusion or poor concentration
  • Fatigue and Exhaustion
  • Appetite Changes
  • Social Withdrawal
  • Changes in Sexual Desire
  • Acne and Pimples
  • Headache
  • Diarrhea

Since you will feel a lot more stressed and uneasy when you have PMS, cutting back on caffeine will make you calm. Also, avoid other related symptoms, such as crankiness. While some research suggests that caffeine consumption has no effect on PMS symptoms, excessive caffeine consumption can cause gastrointestinal issues or bloat.

 3. Drinking Water Can Stop Weight Gain During Periods

Drinking water during your periods will keep your cells hydrated, help you flush out the toxins from your colon, and keep your metabolism active. This, in turn, will prevent weight gain before and during your periods.
