Chewing gum after surgery speeds resolution of gas pain, according to WebMD. The digestive system effectively shuts down during surgery, especially if abdominal organs are involved. Patients who chew gum, which stimulates saliva production, experience faster return of normal bowel function and relief from discomfort caused by gas.
Walking or sitting upright in a chair can also help restore normal digestive function after surgery, reports InformedHealthOnline.org. Getting out of bed and performing gentle physical exercise and abdominal massage reactivate the bowels and help dissipate residual gas buildup following surgery. Drinking warm liquids, chewing food carefully and eating slowly are other helpful measures.
