Frequent belching (hiccups) after surgery may be related to gastrointestinal tract dysfunction, intraoperative stimulation, postoperative medication, micronutrient deficiencies, anesthetic stimulation and other reasons. 1. Gastrointestinal tract dysfunction: the gastrointestinal function of patients after surgery is relatively poor, which will easily cause indigestion and slow gastrointestinal peristalsis will lead to frequent belching (hiccups) after surgery. 2. Intraoperative stimulation: If air enters the abdominal cavity during surgery, the diaphragm will be stimulated or infected, which will lead to frequent belching (hiccups) after surgery. 3. Post-operative medications: The use of certain anti-inflammatory medications such as acetaminophen tablets and celecoxib capsules after surgery can cause diaphragmatic spasms, which can lead to frequent belching (hiccups) after surgery. 4. Micronutrient deficiencies: low levels of sodium, calcium and other micronutrients in the body after surgery can cause the diaphragm to become excited and convulsive, leading to frequent belching (hiccups) after surgery. 5. Anesthesia stimulation: If general anesthesia surgery, anesthesia may stimulate the mucosa of the gastrointestinal tract, so that the gas in the gastrointestinal tract increases abnormally, thus leading to frequent belching (hiccups) after surgery. It is recommended that patients after surgery to easy to digest food, under the guidance of the doctor’s active treatment will be relieved, the drug should be used in accordance with medical advice.
