What should I do if I lose weight and can't have my period

Losing weight may lead to menstrual disorders, which may be related to excessive dieting, low body fat percentage, hormonal imbalances, and other factors. It is necessary to adjust the diet structure, restore body fat percentage, and seek medical examination to address these issues.

1. Excessive dieting

Long term insufficient calorie intake can affect the function of the hypothalamic pituitary ovarian axis, leading to reduced secretion of gonadotropin-releasing hormone. It is recommended to have a daily calorie intake of no less than 1.2 times the basal metabolic rate, increase the intake of high-quality proteins such as eggs and lean meat, and supplement nutrition with compound vitamin B tablets. Typical manifestations include a decrease in menstrual flow before cessation, which may be accompanied by symptoms such as dizziness and fatigue.

2. Low body fat percentage

When a woman's body fat percentage is below 17%, the level of leptin secreted by adipose tissue decreases, affecting estrogen synthesis. It is necessary to gradually increase weight to restore body fat to 22% -25%, and consume healthy fats such as avocados and nuts, while also engaging in moderate exercise such as Ba Duan Jin. Commonly seen in weight loss individuals with a BMI below 18.5, it is often accompanied by poor circulation such as cold hands and feet.

3. Hormonal disorders

Rapid weight loss may lead to thyroid dysfunction or hyperprolactinemia. It is recommended to test six levels of sex hormones and five levels of thyroid function. Clinically, estradiol valerate tablets are commonly used to regulate the menstrual cycle, while bromocriptine tablets are used to treat hyperprolactinemia. This type of condition is usually accompanied by specific symptoms such as hirsutism and lactation, and diseases such as polycystic ovary syndrome should be ruled out.

4. Excessive exercise

High intensity exercise depletes glycogen reserves, activates the hypothalamic stress pathway, and inhibits gonadotropin secretion. The intensity of exercise should be reduced to within 150 minutes of moderate intensity exercise per week, and some aerobic exercises can be replaced with yoga or Pilates. Commonly seen in marathon runners and other long-term endurance trainers, there is a history of delayed menstruation after exercise before menopause.

5. psychological stress

Chronic stress caused by weight loss anxiety can increase cortisol and inhibit follicle stimulating hormone secretion. Stress can be relieved through mindfulness meditation, and if necessary, use estazolam tablets as prescribed to improve sleep. This group of people is often accompanied by abnormal neural regulation such as hair loss and insomnia, and their scores on psychological assessment scales often significantly increase.

It is recommended to restore a balanced diet to ensure a daily calorie intake of 30 calories per kilogram of body weight, and choose low GI foods such as whole grains and dark vegetables. Conducting resistance training three times a week can help increase muscle mass and avoid sustained calorie deficits. If there is no recovery after 3 menstrual cycles, it is necessary to check for premature ovarian failure and other issues. Weight loss drugs or laxatives are prohibited.
