What to do about loose, sagging skin and stretch marks on the abdomen after pregnancy

Under normal circumstances, loose and sagging abdominal skin with stretch marks after pregnancy may be caused by factors such as rupture of dermal elastic fibers during pregnancy, rapid weight loss postpartum, poor skin nutrition, abdominal wall laxity, or hypothyroidism. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through general care, medication, and other treatments. A detailed analysis is as follows:

1. Rupture of skin elastic fibers during pregnancy: As the uterus enlarges during pregnancy, the abdominal skin is excessively stretched, causing the elastic fibers to tear and form stretch marks. Once the skin loses structural support, it becomes loose. After delivery, clean the abdomen daily with warm water and perform clockwise massages to promote absorption. Practicing diaphragmatic breathing regularly can also help strengthen abdominal muscles.

2. Rapid weight loss postpartum: A sharp decrease in body weight shortly after childbirth leads to a quick reduction in abdominal fat, leaving the skin unable to retract in time, resulting in looseness. Avoid losing weight through restrictive dieting. Instead, adopt a balanced diet combined with postnatal recovery exercises to gradually lose weight. Ensure sufficient daily intake of protein-rich foods such as fish and chicken to provide essential materials for skin repair.

3. Poor skin nutrition: Deficiency in nutrients such as vitamin C and collagen after childbirth reduces the skin’s ability to regenerate, worsening skin laxity and stretch marks. Increase consumption of collagen-rich foods like pig trotters and wood ear mushrooms, along with fruits and vegetables such as oranges and spinach. Take nutritional supplements including vitamin C tablets, vitamin E soft capsules, and compound amino acid capsules as directed by a physician.

4. Abdominal wall laxity: The abdominal muscles and fascia become thinner and weaker due to prolonged stretching during pregnancy, leading to noticeable abdominal sagging and a feeling of heaviness. Begin with exercises such as crunches and planks to strengthen abdominal muscles. If these are ineffective, consider abdominoplasty (tummy tuck), a surgical procedure that removes excess skin and tightens the abdominal muscles.

5. Hypothyroidism: Insufficient thyroid hormone secretion slows down metabolism and reduces skin elasticity, making it harder for stretch marks and loose skin to recover. Follow medical advice to take medications such as levothyroxine sodium tablets, thyroid tablets, or levothyroxine sodium enteric-coated tablets to regulate hormone levels, and have thyroid function tests regularly.

In daily life, wear loose and comfortable clothing to avoid friction and irritation to the abdominal skin. Avoid engaging in intense physical activity too early after childbirth; instead, gradually increase exercise intensity according to your recovery progress. Consistent care and exercise over time can effectively improve the condition of the abdomen.
