Any health disorder that affects the digestive tract is referred to as a digestive ailment. Conditions may range from mild to serious. Functional and structural are the two types. The GI tract appears normal, but it does not function properly. It is functional illness. They are the most frequent gastrointestinal issues (including the colon and rectum). Common symptoms include constipation, irritable bowel syndrome (IBS), nausea, bloating, GERD, and diarrhea. The term "structural gastrointestinal illnesses" refers to conditions in which the colon looks odd and does not function properly. Surgical removal of the anomaly may be required. Strictures, stenosis, hemorrhoids, Diverticular disease, colon polyps, colon cancer, and inflammatory bowel disease are all instances of structural GI illnesses.
