What's wrong with gaining weight during menstruation

Weight gain during the period may be related to hormone fluctuations, water and sodium retention, increased appetite, metabolic changes, gastrointestinal motility and other factors. This is a common physiological phenomenon during the menstrual cycle, and there is usually no need to worry excessively.

1. Hormonal fluctuations

The decrease in estrogen and progesterone levels before menstruation leads to an increase in aldosterone secretion in the body, which promotes the reabsorption of water and sodium ions by the kidneys. This hormone change will cause temporary fluid retention, which is manifested as weight gain. Moderate supplementation of vitamin B6 can help regulate hormone balance.

II. Water sodium retention

The increase of progesterone level in luteal phase will inhibit the secretion of antidiuretic hormone, making it easier for water to accumulate in tissue gaps. It is recommended to reduce the intake of high salt foods and increase potassium rich foods such as bananas and spinach, which can help promote water excretion.

III. Increased appetite

Premenstrual decrease in serotonin levels may trigger a craving for carbohydrates and sweets. Choosing low glycemic index foods such as whole grains and nuts instead of refined sugars can satisfy appetite and avoid drastic fluctuations in blood sugar levels.

IV. Metabolic Changes

Basal body temperature may increase during the luteal phase, but some women may experience a temporary decrease in basal metabolic rate. Maintaining moderate exercise such as brisk walking or yoga can help maintain normal metabolic levels.

Fifth, slow gastrointestinal peristalsis

Progesterone can relax smooth muscles, leading to weakened gastrointestinal motility, which may cause constipation and bloating. Increasing dietary fiber intake, drinking warm water in moderation, and gently massaging the abdomen can improve symptoms.

The weight fluctuation during menstruation is usually within the range of 2-3 kilograms, and it will naturally recover after the end of menstruation. It is recommended to maintain a regular sleep schedule, with a daily water intake of 1500-2000 milliliters, and to increase aerobic exercise time appropriately for the last three days after menstruation. If the weight continues to increase by more than 5 kilograms or is accompanied by severe edema, pathological factors such as thyroid dysfunction or polycystic ovary syndrome should be investigated. Menstrual diet should pay attention to balanced nutrition, prioritize choosing red meat and animal liver rich in iron, and pair them with citrus fruits with high vitamin C content to promote iron absorption and avoid excessive intake of caffeine and alcohol that can worsen discomfort.
