Cause analysis:

Losing weight can easily lead to endocrine disorders and malnutrition, thus affecting estrogen secretion, resulting in delayed menstruation, less menstrual flow and even amenorrhea. Therefore, during weight loss, we should pay attention to balanced nutrition and not be too hard on ourselves.

Suggestion: Women who lose weight must not reduce the intake of foods rich in protein, vitamins and various trace elements, and keep the intake of 60 ~ 80g per day even if they are fat. Only in this way can we ensure the need of the body to maintain normal activities and maintain normal menstrual cramps.
