The hazards of excessive weight loss

Excessive weight loss may lead to health problems such as malnutrition, endocrine disorders, weakened immunity, and organ dysfunction. Reasonable weight management needs to be achieved through scientific diet and moderate exercise, avoiding extreme dieting or excessive exercise.

1. Malnutrition

Long term insufficient calorie intake can lead to protein, vitamin, and mineral deficiencies, which may result in problems such as anemia and hypoalbuminemia. Excessive control of carbohydrates or fats may lead to ketosis or lipid soluble vitamin deficiencies, manifested as dry skin, hair loss, and delayed wound healing. It is recommended to supplement high-quality protein such as eggs, fish, whole grains, and fresh vegetables and fruits through a balanced diet.

2. Endocrine disorders

Women may experience amenorrhea and ovulation disorders, while men may experience a decrease in testosterone levels. Abnormal secretion of thyroid hormones can lead to a decrease in basal metabolic rate, which in turn increases the risk of rebound. Dysfunction of the hypothalamic pituitary axis may be accompanied by elevated cortisol levels, leading to emotional anxiety and sleep disorders.

3. Decreased immunity

Lack of protein and trace elements can reduce immunoglobulin synthesis and increase the risk of respiratory and urinary tract infections. Reduced immune cell activity may induce recurrent oral ulcers or skin infections. A decrease in lymphocyte count can lead to a weakened vaccination effect.

4. gastrointestinal injury

Long term fasting may cause bile stasis and acid reflux, leading to chronic gastritis or gastric ulcers. Imbalance of gut microbiota can result in alternating constipation and diarrhea, accompanied by bloating and indigestion. Severe cases may develop superior mesenteric artery compression syndrome.

5. Cardiac damage

Electrolyte imbalance such as hypokalemia may induce arrhythmia and even cardiac arrest. The breakdown of myocardial proteins can lead to decreased heart function, resulting in symptoms of fatigue and chest tightness. In extreme cases, acquired long QT syndrome or stress-induced cardiomyopathy may occur.

It is recommended to monitor body mass index and body fat percentage through regular physical examinations to avoid monthly weight loss exceeding 5% of current weight. Diet should ensure a daily basal calorie intake of 1200-1500 calories, including 30% protein, 40% carbohydrates, and 30% fat. Choose low to moderate intensity aerobic exercise combined with resistance training, with no more than 300 minutes per week. If symptoms such as dizziness, palpitations, and amenorrhea occur, seek medical attention promptly to investigate organic lesions.
