As any desease, time is the worst enemy. If the ulcer is inattentive, the condition will turn into cancer. That is the risk.
Ulcerative colitis
diseases ranging from appendicitis, gastroesophageal reflux disease (GERD), and gastric ulcers to the life-threatening cancers of the stomach, colon, liver, and pancreas, and ulcerative conditions like ulcerative colitis and Crohn's disease.
The ulcers in the intestines can mostly seen in few important disease such as crohn's, ulcerative colitis, acid-peptic disease or zollinger ellison syndrome, colon cancer (less likely in your case). It is important to remember that acid-peptic disease induced ulcers or in zollinger ellison syndrome ulcers are mostly found in the small intestine.
The result is a colitis that produces multiple ulcers, which can bleed.
Ulcerative colitis effects the colon and rectum and is a type of inflammetory disease that can cause ulcers in the sides of the colon and rectum. This can be very serious and should be treated right away.
Another life-threatening condition is toxic megacolon. Severe inflammation causes the colon to dilate or stretch, and the thin colon wall may eventually tear.
a serious infection that can produce complications in the intestine itself--such as ulcers, perforations (holes) in the intestinal wall, and tissue necrosis--as well as progress to life-threatening septicemia.
This occurs in cases of the more severe stomach (and duodenal) ulcers. Blood is oxidized, by the time it travels all the way through the intestine and the colon and, therefore, stools appear as blackish or "tarry".
The procedure is relatively common for treating diverticulitis, inflammatory bowel disease, benign or malignant polyps of the colon, and colon cancer.
Colitis is a general term referring to inflammation of the colon, which can be caused by various factors such as infection or autoimmune conditions. Ulcerative colitis is a specific type of colitis that is a chronic inflammatory bowel disease characterized by ulcers in the colon and rectum. Ulcerative colitis is a subset of colitis.
Poorly managed ulcers can bleed, leading to anemia, and sometimes, death. Obstruction can occur where the stomach meets the small intestines since ulcers can cause inflammation. This swelling could block food from passing through the digestive tract and cause vomiting as a symptom. Some ulcers increase the risk of stomach cancer and infections.
