It is possible to eat fish after stitches. Fish is rich in nutrients and protein, which can increase the patient’s nutrition and promote wound healing after eating fish. And fish is particularly easy to digest and absorb, and will not increase the burden on the gastrointestinal tract. Many people think that fish is a hairy product and eating it may cause inflammation and infection in the wound, but this is not correct. After the wound is closed, it usually takes 2-3 days to change the medication, when changing the medication, we should focus on checking whether the wound has redness, swelling, hard knots, subcutaneous fluid, infection and so on. If there is subcutaneous fluid and infection, the fluid should be cleaned out in time, and if necessary, the surface sutures should be removed and the gauze should be stuffed to facilitate drainage, and the dressing change should be reinforced later. If there is an internal abscess or necrotic tissue, it should be cleaned up and continued to be drained with gauze strips and intensified dressing changes.
