General anesthesia carries certain risks to the body, and the side effects that occur under normal circumstances are largely reversible. Common complications include allergic reactions, nausea and vomiting, temporary nerve damage and sore throat caused by intubation. When the patient awakens from anesthesia, nausea and vomiting may occur, which resolves on its own after about an hour. Numbness and pressure in the limbs or other parts of the body due to reduced blood flow as a result of maintaining the same static position for a long period of time during surgery. This can lead to redness and ulcers on the skin, or nerve damage that can take three to six months to repair. If the procedure requires intubation, there may be gum or tooth damage or even a sore throat in the early postoperative period, which can be relieved in about three days. If the patient has poor oral hygiene or has difficulty with intubation, the risk increases further and the recovery time will be longer. Elderly male patients may experience urine retention after the procedure, which usually resolves on its own after a few days.
