Post-hysterectomy bloating is a very common post-surgical reaction in clinical practice. Many patients will have postoperative intestinal distention and bloating after surgery, as long as the peritoneum is opened for open surgery. If an open surgery is done, the stomach and intestines are directly exposed to the air, and gas will definitely enter. In normal people, there is no gas in the abdominal cavity. When gas enters, it will definitely cause flatulence, which will be absorbed through the stomach and intestines and excreted, and after farting and gas is excreted, it will be better. If you do laparoscopy, after hysterectomy, you will be able to inject carbon dioxide into the abdominal cavity through the laparoscope to form a pneumoperitoneum environment, which will definitely cause more gas in the abdominal cavity and more intestinal flatulence. Generally, intestinal flatulence is caused by the painful incision, incision, less activity, slow gastrointestinal peristalsis, plus the pre-operative prohibition of diet, post-operative also do not eat or drink, gastrointestinal peristalsis is particularly slow, slow recovery, will cause intestinal flatulence.
