That feeling of "bloating" before the cycle comes is not a vain fixation! The truth is that women gain weight during periods. Even according to gynecologists, women can gain up to 3 pounds during the cycle. 

Why does this happen?

Hormones, above all

Shortly before menstruation arrives, estrogen levels in the female body are at their highest point. Due to high levels of the female hormone, the body tends to accumulate fluids, which cause bloating. But as the periods come, estrogen levels drop, and you immediately feel lighter.

Hormones again (progesterone)

During the second phase of periods, the level of progesterone rises, which again causes water to accumulate as well as swelling of the chest.

Nepsi!

Yes, during periods it is normal to have cravings for anything, of course, not for broccoli and lettuce. The foods we like the most are generally dry, too salty or too sweet. These also hold water inside the body.

Periods cause rupture and laziness

Swollen, helpless; these are the sensations that usually accompany the cycle. Therefore women become lazy to walk or go to the gym during this period. By not sweating, you do not relieve the body of excess water.
