In a study recently published in Medical Hypotheses (2011 76(1):97-99), Dr. Habba analyzed 575 patients presenting with previously diagnosed diarrhea predominant IBS (IBS-D). 303 patients completed all the testing and follow up necessary to be included in the results. The study concluded that 98% of these patients had conditions other than the previous diagnosis of IBS. When these conditions were identified and appropriately treated, 98% of them improved as assessed by fewer than three bowel movements per day. Habba Syndrome constituted 41% of the patients studied, post-cholecystectomy diarrhea 23%, lactose intolerance 8%, microscopic/lymphocytic colitis 7%, celiac disease 4% and several other specific conditions comprised the balance. This result is very encouraging and is in contrast with the results presently achieved by treating “IBS”. Physicians frequently fall short of “getting to the bottom” of the problem by tagging patients with “IBS”, a vague entity that merely describes their symptoms and usually results in a poor therapeutic outcome.
These findings lead to the theory concluding that there is no IBS-D. Patients need to be evaluated thoroughly until a true clinical entity is found and treated.
