Why Do You Weigh More During Your Period:

Have you ever wondered why you gain those extra pounds, especially during periods? We present you with some of the reasons you weigh more during your menstrual cycle.

1. Impaired Digestion:

There are a lot of hormones involved during the process of menstruation. There is an impairment of the digestion process when there is improper hormonal balance. You can find yourself facing distention, bloating, and gas retention in the stomach during periods since some people fluctuate estrogen and progesterone hormones. When there are issues in your digestive system, it tends to show an increase in your weight.

2. Water Retention:

Water retention might be one of the culprits for gaining weight during your periods. Progesterone and estrogen play an essential role in regulating the balance of water in your body, and the levels of these hormones fall when you are due for your period. This hormone fluctuation results in water retention, resulting in weight gain since tissue fluids accumulate (1). You can feel water retention during periods in the extremities, stomach, or breast.

3. Issues with the Gut:

Bloating, constipation, and indigestion are some of the gut issues many women experience during their periods. Just a few days before your period, there are elevated progesterone levels, which results in slower gut movement. This causes constipation since your entire digestive tract becomes sluggish.

4. Lack of Exercise:

Menstruation can be one of the reasons for skipping workouts for many women. Your body and mind feel sluggish due to the bleeding phase, making you want to rest rather than exercise. This process starts storing fat as you gain water weight.

Although it is impossible to have a regular workout routine during menstruation, practice simple yoga poses and breathing exercises that help you ease the pain during your periods.

5. Magnesium Deficiency:

Magnesium levels tend to drop in your body just before your menstrual cycle. This increases your craving for glucose because the low magnesium levels can lead to lowered insulin levels. When your desires grow, many women consume high-sugar foods, making you gain weight during periods.

6. Food Binging:

Another prominent reason for weight fluctuation during periods is increased cravings for food and overeating. The primary reason for craving sugary and processed foods is the low serotonin levels (2). The estrogen levels in your body fall before your period, directly affecting serotonin levels.

7. Mood Swings:

Whenever you are cranky, you might hear your friends asking whether you are PMSing. Along with food cravings, mood swings are some common symptoms of PMS. In addition, the desire for sweet and salty food results in weight gain because of hormonal gameplay (3).

How Much Weight Gain is Normal During a Period:

PMS(premenstrual syndrome) affects women two weeks or several days before their period and has varied physical, emotional, and behavioural symptoms, such as weight gain caused by hormonal changes.

It is normal for women to gain anywhere from three to five pounds during the menstrual cycle. But don’t worry; it is not a permanent weight gain since you will lose those extra pounds after a few days of bleeding.

Note that your weight gain might last longer, and you might find it challenging to shed those extra pounds if you have PCOS and other metabolic or health issues. If that is the case, consult a gynaecologist immediately.

How Can You Stop Weight Gain During Periods:

Although weight gain is relatively normal among women during the menstrual cycle, you can prevent water retention or weight gain by practising a few healthy habits throughout the month:

  • Regular Exercise: Ensure you exercise at least 20 to 30 minutes of physical activity daily.
  • Hydration: Keeping yourself hydrated is the key to preventing the conservation of fluids in your body.
  • Reduce the Intake of Salt: Avoid foods with high amounts of salt since sodium increases water retention in your body.
  • Avoid Sugar and Caffeine: Avoid sugary foods and caffeinated drinks before your period since they might cause bloating.

It is pretty normal to gain a little weight during the periods, and you will lose it once you are done with the menstrual cycle. Hormonal fluctuations are the primary reason for period-related weight gain, and it can also result from overeating or craving for sugar during this time. The key is understanding your body better and making necessary changes to avoid long-term weight gain. Don’t forget to let us know if this article was helpful!
