What is the reason for normal limbs and big belly?

Normal belly enlargement of limbs may be caused by visceral fat accumulation, abdominal muscle relaxation, intestinal flatulence, abdominal effusion, hormonal imbalance and other reasons.

1. Visceral fat accumulation:

Long-term high-calorie diet and lack of exercise can cause fat to be deposited around the internal organs, forming central obesity. This kind of fat has high metabolic activity and can easily cause insulin resistance and increase the risk of diabetes and cardiovascular disease. Waist circumference ≥90 cm for men and ≥85 cm for women can be judged as excessive visceral fat. It is recommended to improve it through aerobic exercise and reducing refined carbohydrate intake.

2. Abdominal muscle relaxation:

Postpartum women or those who lack core exercise for a long time may develop rectus abdominis diastasis, which is manifested by reduced abdominal muscle support. Pregnancy hormones will cause the abdominal linea alba to relax, and failure to repair it in time after delivery will lead to lordosis of the organs. Targeted training such as plank support can enhance the strength of the transversus abdominis. In severe cases, an abdominal belt may be worn to assist recovery.

3. Intestinal flatulence:

People with lactose intolerance or irritable bowel syndrome often produce excessive gas due to digestive disorders. After eating gas-producing foods such as beans and onions, the fermentation of intestinal flora will produce methane and hydrogen, which will increase the abdominal circumference by 3-5 cm in a short period of time. It is recommended to keep a food diary to check for allergens and supplement digestive enzymes if necessary.

4. Abdominal effusion:

Diseases such as cirrhosis and heart failure can cause portal hypertension, causing fluid to leak into the abdominal cavity to form ascites. The patient's abdomen was frog-shaped when lying supine, and there was shifting dullness upon percussion. You need to be vigilant if your daily weight fluctuates by more than 1 kilogram. Ultrasound examination can determine the amount of fluid accumulation. Treatment needs to target the primary disease while limiting sodium intake.

5. Hormone imbalance:

Cushing's syndrome with excessive secretion of cortisol causes centripetal fat distribution, manifesting as a moon face, buffalo back and abdominal distension. Long-term stress or adrenal tumors may cause this symptom. Diagnosis requires testing of 24-hour urinary free cortisol. Treatment includes surgical removal of the tumor or drugs to inhibit cortisol synthesis.

To improve abdominal distension, intervention measures must be taken based on the specific causes. For those with visceral fat, 150 minutes of moderate-intensity exercise per week is recommended along with a Mediterranean diet. ； Postpartum abdominal muscle relaxation can be performed with Kegel exercises to restore pelvic floor function ； Intestinal problems should increase dietary fiber and supplement probiotics ； Pathological ascites requires strict monitoring of daily intake and output. People over 40 years old who suddenly experience abdominal enlargement accompanied by weight loss should promptly investigate the possibility of tumors. Shapewear with moderate elasticity can be worn daily to provide support, but should not be worn for more than 8 hours a day to avoid affecting blood circulation.
