Hi. Thanks for your query. Noted the history and understood your concerns. Constipation for 2 weeks can be due to many factors as it has a short history. Dehydration. Changed food habits. Stress and anxiety. THe reports of Upper GI Endoscopy showing duodenopathy and multiple erosions is not related to constipation as this may be due to hyperacidty. A proper treatment with a PPI like Omeprazole, antacids, soft bland diet may solve this problem. Colonoscopy being normal except internal hemorrhoids means there is no cancer of the colon which is one of the reasons for constipation. I would advise you the following: Discuss the actual problem with your Gastroenterologist as it may be the feeling of being constipated and mostly related to the stress and anxiety like IBS that is irritable bowel syndrome. Take a proper laxative and go for high fiber diet with plenty of oral fluids.
