Introduction
Thick fat accumulation may result from excessive eating, lack of physical activity, aging, hypothyroidism, polycystic ovary syndrome (PCOS), and other factors. It can be improved through dietary control, increased physical activity, lifestyle adjustments, and medication. If there is abnormal fat deposition or symptoms such as fatigue and menstrual irregularities, prompt medical attention is necessary. Long-term consumption of high-calorie, high-fat foods

Excessive fat accumulation may result from overeating, lack of physical activity, aging, hypothyroidism, polycystic ovary syndrome (PCOS), and other factors. It can be improved through dietary control, increased physical activity, lifestyle adjustments, and medical treatment. If abnormal fat accumulation occurs alongside symptoms such as fatigue or menstrual irregularities, prompt medical consultation is recommended.

1. Overeating: Long-term consumption of high-calorie, high-fat foods leads to caloric surplus, which the body stores as fat, resulting in increased fat deposition. It is recommended to control total calorie intake, reduce fried foods and sweets, and consume more whole grains, vegetables, and fruits.

2. Lack of physical activity: Prolonged sitting and insufficient exercise reduce fat burning, leading to gradual fat accumulation throughout the body or in specific areas. It is recommended to engage in aerobic exercise at least three times per week, combined with strength training, to promote fat metabolism.

3. Aging: Metabolic rate declines with age, and hormonal changes make fat accumulation more likely, especially in the abdominal and hip areas. It is advisable to adjust dietary patterns and increase daily physical activity to slow down fat buildup.

4. Hypothyroidism: Insufficient thyroid hormone secretion slows metabolism, leading to fat accumulation, often accompanied by fatigue, cold intolerance, and weight gain. Under medical guidance, medications such as levothyroxine sodium tablets, thyroid tablets, or liothyronine sodium tablets may be used to improve symptoms.

5. Polycystic ovary syndrome (PCOS): Hormonal imbalances affect metabolism, causing abdominal fat accumulation, along with menstrual disorders and hirsutism. Under a doctor’s supervision, patients may use medications such as ethinylestradiol cyproterone acetate tablets, drospirenone-ethinyl estradiol tablets, or metformin hydrochloride sustained-release tablets to alleviate symptoms.

Maintain a regular sleep schedule and avoid staying up late. Eat a balanced diet rich in protein and dietary fiber, drink plenty of water to support metabolism, consistently engage in moderate exercise, and maintain a positive mindset—all of which help control fat accumulation and promote overall health.
