Menstruation refers to menstruation, and it is possible to gain weight before menstruation, but it is not absolute. Before menstruation, the levels of estrogen and progesterone in a woman’s body will change significantly, especially when estrogen levels are too high, which may lead to water and sodium retention in the body, which in turn leads to weight gain. However, as the hormone levels in each woman are different, some women may not have significant changes in hormone levels, which may not result in significant sodium retention, so they generally do not gain weight. Therefore, whether or not you will gain weight before your period varies from person to person. If weight gain occurs, there is no need for special treatment, it is a normal physiological phenomenon, after the end of menstruation, the body hormone levels return to normal, the weight can be normalized.
