Hi thanks for contacting HCM... Noted you have chronic constipation... Along with more water you have to do regular exercise... More water.... Beet greens rich in iron , calcium and beta carotene so taken to maintain healthy digestion... Avocados fruit rich in fiber and good to take... Blueberries rich in fiber and vitamin c with contain antioxidant ....so help in proper digestion.... Fiber rich food taken more like whole grain , wheat bran , apple , beans etc found to be help in digestion.... Chamomile in tea useful... Green tea also useful... Avoid gassy food like cabbage , onion , turnip etc.... If still no benefit laxative needed like polyethelene glycol .... If still needs investigation USG and x ray done for rule out organic causes.... Take care. Dr.Parth
