What causes weight gain on menstruation?

Weight gain during menstruation may be caused by sodium retention, dietary factors, and low exercise.
1. Sodium retention: During menstruation, changes in hormone levels may lead to sodium retention, which makes it difficult for water to be discharged and may lead to weight gain.
2. Dietary factors: During menstruation, some women may have an increased appetite and eat frequently, which may lead to weight gain.
3. Low physical activity: During menstruation, due to the discharge of menstrual blood, women’s physical activity decreases and fat accumulates, which can lead to weight gain.
If weight gain during menstruation is accompanied by other clinical symptoms, it is recommended to consult a doctor for timely examination and targeted treatment under the guidance of a professional doctor.
