Abdominal bloating after pancreatic cyst surgery may be caused by improper diet, intestinal adhesion and intestinal obstruction. 1. Improper diet: If patients don’t pay attention to diet after pancreatic cyst surgery and eat some greasy, spicy and other stimulating food, it may cause digestive tract reaction, which may lead to abdominal distension, nausea and other symptoms. 2. Intestinal adhesion: During pancreatic cyst surgery, due to the local tissue damage during the surgery, there is a possibility of intestinal adhesion after the surgery. As the food in the intestines can not pass through normally, it may lead to abdominal distension of the patient. 3. Intestinal obstruction: after the surgery of pancreatic cyst, the abdominal cavity environment may be damaged, resulting in an inflammatory reaction in the cavity. Due to the mutual adhesion of intestinal tubes, the intestinal tubes cannot be blocked, thus inducing intestinal obstruction, which may also lead to abdominal distension. When patients experience abdominal distension after pancreatic cyst surgery, it is recommended to go to the hospital for a detailed examination to determine the cause of the disease, and then actively cooperate with the treatment under the guidance of the doctor.
