It is best for patients to quit smoking after hemorrhoid surgery, which may lead to the following two situations: First, smoking after surgery may lead to coughing, and the process of coughing can lead to increased abdominal pressure, which can cause impaired circulation in the local incision, leading to the possibility of local bruising and even bleeding. Second, smoking will inhale nicotine, which has the effect of constricting small blood vessels, causing spasmodic constriction of small blood vessels, which may affect the healing of the incision after surgery, so smoking is prohibited for patients after hemorrhoid surgery. You should also prohibit eating spicy and irritating foods, drinking strong liquor, and keeping your bowels open to prevent constipation.
