After being discharged from the hospital, patients who have been treated for a bowel obstruction typically start with a clear liquid diet for several days and then gradually consume solid foods, according to MedlinePlus. Instead of large meals, they must eat frequent, equally spaced, small meals.
Doctors advise sipping clear fluids throughout the day and slowly adding one or two foods into the diet of a patient who has had a bowel obstruction, notes MedlinePlus. While recovering, patients should avoid foods that usually cause constipation, loose stools or gas. It is important to stick with only clear liquids if the patient experiences diarrhea or stomach discomfort. It is also essential for patients to avoid performing strenuous exercises or lifting heavy objects for four to six weeks unless the doctor says otherwise.
