7 Major Causes For Weight Gain During Periods

1. PMS

PMS or premenstrual syndrome begins one or two weeks before the actual period commences. And its most obvious symptoms are bloating, anxiety, food cravings, and depression. These result in a craving for sugary and salty foods and binge eating. As a result, by the end of the PMSing phase and the start of your period, you gain about 5 pounds of weight.

2. Food Cravings

Increased food cravings and overeating can also be other causes for weight gain before and during periods. When you are PMSing, you are under mental stress, and to feel good, you end up eating high-sugar and high-sodium foods. This results in increased water retention and spikes blood glucose levels.

3. Water Retention

Water retention is one of the main reasons for weight gain during periods. Water that is absorbed in the body from different sources during the day is retained by the body tissues during menstruation. This retention of water also known as edema influences the body because of severe hormonal changes that occur during the periodic cycle. It is common for any woman to feel bloated at such times. In fact, any changes in the bowel movements can also result in edema. But the main reason is the sudden and abrupt decrease in the progesterone levels in the body.
