Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. Your father seems to suffer from-IBS with GERD mostly. There fore you need Rekool-L/ D-prokinetics preventing the reflux and reducing the hyperacidity-with rabeprazole.Go for the generic version-like prilosec with domeperidone-which would reduce the cost of treatment. But be after-meticulous diet change-with bland diet/yoghurt helpings/buttermilk daily and correction of the infection recurrence-by antibiotics with anti-protozoal,which are the cause of recurrence. Avoiding street fast food,restricting spicy,fried food/are important diet changes, which would give long remissions without medicines with good health. Consults with Physician and Surgeon and meticulous follow up of diet and timely medicines x for few mths,would resolve this recurring illness with long remissions.
