After lumbar spine surgery, diet should pay attention to avoid spicy and stimulating foods, alcohol and alcoholic beverages, carbonated drinks, etc. 1. Spicy and stimulating foods: After lumbar spine surgery, avoid spicy and stimulating foods, such as chili peppers and peppercorns, because they may aggravate the pain and infection of the incision. 2. Alcohol and alcoholic beverages: avoid drinking alcohol and alcoholic beverages, because after drinking alcohol and alcoholic beverages, it is easy to affect the blood flow in the incision area, which is not conducive to the recovery of the incision, and it is also easy to cause infection of the incision in the later stage. 3. Carbonated beverages: Drinking carbonated beverages should also be avoided, as they may lead to decalcification of the bone area and cause osteoporosis, thus affecting the recovery after lumbar spine surgery. In addition to paying attention to diet, patients after lumbar spine surgery are advised to go to the hospital for regular checkups.
