Aunt refers to menstruation. Weight gain before menstruation is usually normal and not a cause for concern, and will recover on its own after menstruation.
Before menstruation, estrogen levels in the body will rise, and estrogen causes water and sodium retention. Since water cannot be easily excreted, a slight increase in weight will occur, which is normal before menstruation and will not adversely affect the body.
After menstruation, the level of estrogen in the body gradually decreases and stabilizes, and the phenomenon of water and sodium retention gradually decreases and disappears, and after the edema is eliminated, the weight will return to the normal level.
If you find rapid weight gain and obvious symptoms of edema, you should go to the hospital in time to do blood routine, renal function and ultrasound and other tests to rule out the possibility of diseases causing weight gain.
