Hi ! Good morning. I am Dr Shareef answering your query. The pain could be due to some kind of sub acute intestinal obstruction due either to adhesion formation inside the abdomen or due to partial herniation of part of the gut nearby the colostomy site. This can be judged only by a clinical examination at the time of pain abdomen, and also a plain X ray of the abdomen in upright posture could possibly help in it. However, the pain could also be due to the original lesion for which a colostomy was performed. Ingesting acidophilus supplement would not do any harm to him and so could be tried. If I were your family physician, I would refer either to your original surgeon, or would not hesitate to take a second opinion for a judgmental decision by the doctor. I hope this information would help you in discussing with your family physician/treating doctor in further management of your son s problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your son s health problems. I wish him an early relief. Dr Shareef
