Dr. David Samadi, prostate cancer expert, helps viewers understand the various types of colitis, their causes, and treatments. This brief overview covers ulcerative colitis and infectious colitis. Ulcerative colitis, he explains, is indicated by fever, diarrhea, and joint pain or swelling. If ulcerative colitis persists for 7 or more years, the risk of colon cancer is increased. Infectious colitis scan be contracted during travel and is usually treated with antibiotics. Symptoms include abdominal pain, weight loss, and blood or pus in the stool. If antibiotics are ineffective, a colonoscopy is performed to better diagnose the issue. Dr. Samadi recommends plenty of fluids, starchy foods, and bananas for colitis sufferers.
