Hello, Welcome to HCM. Yes,it is quite possible that your stool frequency could become irregular due to because of continuous ingestion of potatoes. It could be due to fatty dyspepsia or indigestion which in turn could be due to acute gastritis or,irritable bowel syndrome (IBS) or inflammatory bowel disease or parasitic infestation (giardiasis). If you were my patient then I will give below instructions for some relief. 1) You should take frequent small feeds rather then two large meals. 2) Pain killers should be avoided if you are taking them. 3) Avoid carbonated drinks,caffeine products. 4) The food that you are eating should be chewed well . 5) You should walk for few metres after every small meal. 6) You should not lie down or sit on the couch immediately after meal. 7) Take high fiber diet,fresh fruits which will move easily in the gut. 8) Avoid excess oil,ghee and fatty or junk food. You can take oflox-oz which is a very good drug specially in the treatment of gastro-intestinal infection but you should also take proton pump inhibitors like pantoprazole or rabeprazole which will reduce the excess acid production in stomach with anti-emetics like ondasetron. Consult physician for further treatment. Regards,
