The term “great aunt” is generally used to refer to a woman’s menstrual period. Weight gain during menstruation is associated with poor diet, decreased activity level and hormonal effects in the body. 1. Improper diet: For some menstruating women, if they overeat or consume high-calorie, high-sugar and high-fat foods during this period, they will gain weight to a certain extent. 2. Decrease in activity: When the activity level of menstruating women decreases, they cannot consume excess calories and fat in time, which leads to weight gain for some women during menstruation. 3. Hormonal effects: during menstruation, most women can be prompted by changes in hormone levels in the body sodium retention, thus showing limb edema, weight gain and so on. Usually after menstruation, the weight will gradually return to normal, so there is no need to worry too much. During menstruation, women should not be overly concerned about weight changes and should remain physically and mentally happy. They should also pay attention to proper diet and rest, and avoid over-exertion.
