Following colon resection, it is common to have symptoms such as frequent, loose bowel movements, constipation and abdominal pain, according to Healthgrades. These symptoms are very similar to the diarrhea, constipation and abdominal pain that are the key symptoms of IBS, according to the International Foundation for Functional Gastrointestinal Disorders.
Depending on how much of a person's colon or small intestine is removed during surgery, these types of symptoms often improve with time, according to Keck School of Medicine of USC. Avoiding spicy foods or foods that upset the stomach for the first few weeks may be helpful in reducing symptoms. It can take four to six weeks for bowels to become more regular.
