You cannot smoke after appendicitis surgery because of the following reasons: 1. Appendicitis surgery requires general anesthesia, which requires routine tracheal intubation during general anesthesia, and after tracheal intubation, sputum is easily deposited in the organism, which can easily cause pneumonia. 2. If you smoke at this time, it will lead to aggravation of pneumonia, so you can’t smoke. 2. If you smoke after appendicitis surgery, it may aggravate or cause coughing, leading to increased abdominal pressure. This is because the appendicitis surgery can cause pain in the incision and may even cause the incision to open up, so you cannot smoke after the appendicitis surgery. Appendicitis surgery is the most common emergency surgery in clinical general surgery. The typical symptom is metastatic right lower abdominal pain, mostly due to the usual inattentive diet, overeating or eating too much spicy and stimulating food, etc., which leads to appendiceal congestion and edema and inflammation. Once the diagnosis of appendicitis is clear, timely surgery is required.
