Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. Your father seems to suffer from-IBS D followed by C. The frequent bowel movements with Stomach pains is one of the main indication,but needs to be verified from other causes of IBS-like amoebiasis/giardiasis/Deveritculosis/TB Entero-colitis/Crohn s disease /Celiac disease/ Ulcerative Colitis. Dear the base of the diagnosis is not the Diagnosis of the IBS, but what is causing this IBS and needs to be ruled out by team of doctors-like Physician/GI specialist/GI Surgeon if need be. For this strict besides medicines for the causative facts, diet control is a must if its IBS, and needs to be accompanied with treatment of the causative bacteria/or protozoa. So controlling the stomach control should be aimed by-change in the dietary habits-and should not be treated only with Loperamide. Bland diet/high fibre diet/yoghurt -butter milk helpings daily/Spinach soups when in constipation along with isaphgol/ antibiotics/ anti-protozoal medicines ,would give long remissions even without medicines. Hope this would help you to plan further care of this complex illness of yours.
