Women may experience a mild weight gain before menstruation, which is due to the increase in the level of estrogen in the body before menstruation causing water and sodium retention in the body, thus causing excess water in the body resulting in weight gain. After the onset of menstruation and when the menstruation clears, the body hormones will gradually return to their original level, and the metabolism of the body will be faster within two weeks after the end of menstruation, and the weight will return to the original state, which is a normal physiological process and does not require weight loss. However, if water and sodium retention is more serious and severe edema occurs, certain diuretics can be given under the guidance of a doctor to improve this symptom, if the weight is only mildly increased no measures need to be taken. During menstruation, pay attention to hygiene, do not catch cold, eat reasonably and keep the vulva clean and hygienic.
