Thank you for posting your query. incomplete history provided. why block in esophagus? any other chronic disease at present? what medications were used? anyhow,need further evaluation as soon as possible. -you husband needs to undergo colonoscopy at the earliest to rule out any benign / malignant lesion. -also Liver function test should be done alongwith complete blood cell count meanwhile, advice: -warm water intake - eat small meals - fresh oranges and pear - avoid COLD milk and yogurt and AVOID junk food(NO burger , pizza) altogether - drink strong coffee (once only) on empty stomach to aid in bowel movement - include fiber rich food in your diet - OTC lactulose drug maybe used also - simethicone tablet for bloating hope the bowel movement would be normal. any further questions are welcomed. hope to answer your concern. Health professionals aim to diagnose properly and manage patients according to their limited knowledge. Cure is blessed by the ONE who Created us, whose power and knowledge is unlimited . wish you good health. regards, Dr Tayyab Malik
