The dangers of multiple diverticula of the ascending colon include causing symptoms such as diarrhea and abdominal pain, and affecting the patient’s life. If left untreated, it can also cause complications such as diverticulitis. Multiple diverticula of the ascending colon refers to the formation of multiple cystic protrusions outward from the wall of the ascending colon, and the disease occurs in association with structural defects in the intestinal wall and dietary deficiencies in dietary fiber. Multiple diverticula of the ascending colon may not generally cause abnormalities in the human body, but it may also cause diarrhea, abdominal pain, abdominal distension and other hazards, thus affecting the patient’s daily life. If the patient is not treated in time, diverticulitis, diverticular hemorrhage and other complications can also be caused, thus jeopardizing human health. It is recommended that patients go to the hospital in a timely manner and follow the doctor’s instructions to standardize the treatment, so as not to delay the condition.
