What is the reason for low menstrual flow during the weight loss period

Low menstrual flow during the weight loss period may be related to factors such as excessive dieting, malnutrition, hormonal imbalances, mental stress, and polycystic ovary syndrome. Excessive control of diet during weight loss may lead to insufficient energy in the body, affecting the function of the hypothalamic pituitary ovarian axis, and ultimately resulting in reduced menstrual flow or even amenorrhea.

1. Excessive dieting

Excessive dieting can lead to insufficient energy intake in the body, affect hypothalamic function, reduce the secretion of gonadotropin-releasing hormone, and thus affect follicle development and estrogen levels. A decrease in estrogen levels can lead to insufficient endometrial hyperplasia and a decrease in menstrual flow. Suggest adjusting the dietary structure to ensure sufficient daily intake of calories and nutrients, and avoiding extreme dieting.

2. Nutritional deficiencies

During weight loss, a lack of key nutrients such as iron, protein, and essential fatty acids can affect hemoglobin synthesis and hormone secretion. Iron deficiency may lead to anemia and affect the blood supply to the endometrium; Protein deficiency can affect follicular development; Lack of essential fatty acids can interfere with hormone synthesis. It is recommended to consume lean meat, animal liver, deep-sea fish, nuts and other foods rich in these nutrients in moderation.

3. Hormonal disorders

Rapid weight loss may lead to a decrease in leptin levels, which in turn affects the secretion of gonadotropins. Meanwhile, increased secretion of adrenal cortex hormones can inhibit ovarian function. This hormonal imbalance can lead to abnormal menstrual cycles and reduced menstrual flow. It is recommended to regulate the endocrine system through moderate exercise, regular sleep, and other methods. If necessary, medication such as progesterone capsules and estradiol valerate tablets can be used according to medical advice to regulate the menstrual cycle.

4. psychological stress

The psychological stress generated during weight loss can stimulate cortisol secretion and inhibit hypothalamic function. Long term stress may also lead to abnormal secretion of follicle stimulating hormone and luteinizing hormone, affecting follicular development and ovulation. It is recommended to relieve stress through meditation, yoga, and other methods, ensure sufficient sleep, and seek psychological counseling if necessary.

5. Polycystic Ovary Syndrome

Some obese women themselves suffer from polycystic ovary syndrome. Improper weight loss methods may exacerbate insulin resistance and elevated testosterone levels, leading to menstrual disorders. The typical symptoms include infrequent menstruation and reduced menstrual flow, which may be accompanied by symptoms such as acne and hirsutism. After diagnosis, medication such as ethinylestradiol and cyproterone acetate tablets can be used under the guidance of a doctor to regulate hormone levels. During the weight loss period, a balanced diet should be maintained, with daily calorie intake not lower than the basal metabolic requirements, ensuring a reasonable ratio of high-quality protein, complex carbohydrates, and healthy fats. Moderate intake of whole grains rich in vitamin B, red meat rich in iron, and dark vegetables can be increased. Avoid long-term low carbohydrate diets and engage in 3-5 moderate intensity aerobic exercises per week, combined with strength training to maintain muscle mass. If there is a significant decrease in menstrual flow or amenorrhea for more than 3 months, it is necessary to seek medical attention promptly to check hormone levels and endometrial condition, and rule out organic diseases. It is not recommended to take hormone drugs to regulate menstruation on one's own, and intervention should be carried out under the guidance of a professional physician.
