Physiological period generally refers to the menstrual period, during menstruation women’s weight will generally become heavier, but due to individual differences, it is impossible to generalize. During menstruation, most women experience fluctuating levels of estrogen and progesterone, and their metabolism slows down, which may lead to water and sodium retention in the body, resulting in short-term edema, which is manifested as heavier body weight. This is a normal phenomenon. After menstruation, the metabolism of the body will return to normal, the edema will subside on its own, and the weight will return to normal. Some patients have different body types and may not experience edema and weight gain during menstruation, but may also experience weight loss, so it is not possible to generalize. During menstruation, women need to ensure sufficient rest time and avoid staying up late for a long time. Keep a good and positive mindset, do not be overly emotional. At the same time, you should pay attention to local cleanliness, change underwear and sanitary napkins to avoid secondary infection.
