What are the consequences of losing weight leading to missed menstruation

Losing weight can lead to menstrual disorders, osteoporosis, impaired fertility, and other health problems. Excessive dieting or exercise may inhibit hypothalamic function, leading to insufficient secretion of gonadotropins, which in turn affects ovarian function and periodic changes in the endometrium. Short term cessation of menstruation may only manifest as menstrual irregularities, but long-term amenorrhea can accelerate bone loss and increase the risk of fractures. Persistent low estrogen levels can lead to a decrease in bone density, especially in young women. Some patients may experience menopausal symptoms such as hot flashes and emotional fluctuations, and their skin elasticity may also deteriorate due to collagen loss.

In severe cases, it may cause premature ovarian failure, leading to irreversible decline in fertility. When the body fat percentage is below the health threshold, the body will activate survival protection and prioritize shutting down reproductive system functions. Some patients may have thyroid dysfunction, resulting in a continuous decrease in basal metabolic rate and a predisposition to obesity.

It is recommended to adopt a gradual weight loss plan, and the weekly weight loss should not exceed one percent of the body weight. Daily intake of high-quality protein, complex carbohydrates, and healthy fats should be ensured, and foods rich in zinc and magnesium such as pumpkin seeds and flaxseed can be moderately increased. If amenorrhea occurs for more than three months, timely medical attention should be sought. Ovarian function should be evaluated through six hormone tests, pelvic ultrasound, and other examinations. If necessary, estrogen and progesterone cycle therapy should be used under the guidance of a doctor.
