What should I do if a wound does not heal for a long time?

Under normal circumstances, delayed wound healing may be caused by factors such as aging, malnutrition, infection, local circulatory disorders, and diabetes. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analysis is as follows:

1. Aging

With advancing age, the activity of fibroblasts in the skin decreases and collagen synthesis reduces, impairing the wound healing process. Meanwhile, declining immune function reduces resistance to infections, thereby prolonging healing time. It is recommended to improve nutrition by consuming protein-rich foods and those high in vitamin C, such as pig's trotters, fish, and rape greens, which can aid wound healing.

2. Malnutrition

A deficiency in proteins, vitamins, and minerals may compromise the nutritional supply required for wound healing, leading to slow recovery. It is advised to adjust the diet to include more foods rich in protein, vitamin C, and zinc, such as fish, tofu, and almonds, to help replenish essential nutrients.

3. Infection

Wound infection is one of the major obstacles to healing. Microorganisms such as bacteria and fungi multiply in the wound, producing toxins and inflammatory factors that disrupt normal healing processes. Symptoms such as redness, swelling, and pain may also appear. It is recommended to clean and debride the wound promptly, keep it clean and dry, and prevent re-infection.

4. Local Circulatory Disorders

Poor local blood circulation leads to insufficient oxygen and nutrient supply to the wound site, thus impairing healing. It is advisable to promote blood flow through methods such as warm compresses and massage.

5. Diabetes

High blood glucose damages microvessels, impairing blood supply to the wound area and delaying tissue repair. Additionally, a high-glucose environment hampers white blood cell function, reducing the body’s resistance to infection. Symptoms such as infection and difficulty clearing necrotic tissue may also occur. It is recommended to follow medical advice in using medications such as insulin injection, metformin hydrochloride tablets, and glimepiride capsules to control blood sugar levels. Regular medication and monitoring can support wound recovery.

If the wound continues to worsen, prompt treatment at a正规 hospital is advised to prevent further deterioration. In daily life, maintain a light diet and avoid spicy or irritating foods such as Sichuan pepper, chili peppers, and onions, which is beneficial for recovery.
