You usually gain a few pounds before menstruation

Premenstrual weight usually increases by 1-3 pounds, which is mainly related to factors such as hormone fluctuations, water and sodium retention, and slowed gastrointestinal motility.

During the menstrual cycle, elevated progesterone levels during the luteal phase can lead to water and sodium retention, increasing the amount of fluid in the interstitial space. Changes in estrogen levels may affect aldosterone secretion, further exacerbating water retention. Some women will experience hyperphagia, especially increased demand for high-sugar and high-salt foods, which may lead to excessive caloric intake. Pelvic congestion and increased uterine size can also temporarily increase weight measurements. These changes are mostly physiological reactions. As hormone levels drop after menstruation, excess water and metabolites are gradually discharged, and weight can recover on its own.

It is recommended to maintain moderate exercise during premenstrual period, such as walking or yoga, to help promote blood circulation and water metabolism. In the diet, reduce the intake of high-salt foods and increase potassium-rich bananas, spinach and other foods to balance electrolytes. Keep the daily water intake at 1500-2000 ml, and avoid drinking large amounts of water at night. Wearing loose-fitting clothing can reduce abdominal pressure, and keeping track of menstrual cycles and weight changes can help distinguish physiological fluctuations from abnormal growth. If the weight does not fall back after menstruation or continues to increase by more than 5 pounds, pathological factors such as thyroid dysfunction or polycystic ovary syndrome need to be investigated.
