Pseudomembranous colitis is a form of inflammatory disease characterized by the pathologic presence of pseudomembranes consisting of mucin, fibrin, necrotic cells, and polymorphonuclear leukocytes. Bacterial IBS is the most common cause of this disease , particularly beyond the first year of life. Allergic IBS is the most common form of colitis during the first year of life. Collagenous colitis and lymphocytic colitis are two other types of bowel inflammation that affect the colon.
A diagnosis of collagenous IBS or lymphocytic IBSis made after tissue samples taken during a colonoscopy or flexible sigmoidoscopy are examined with a microscope. Collagenous IBS and lymphocytic IBS are also called microscopic IBS. Ulcerative colitis is not caused by emotional distress or sensitivity to certain foods or food products, but these factors may trigger symptoms in some people.
For extreme cases of collagenous and lymphocytic that have not responded to medication, surgery to remove all or part of the colon may be necessary.
Ulcerative colitis can occur in people of any age, but it usually starts between the ages of 15 and 30, and less frequently between 50 and 70 years of age. IBS is an inflammation of the colon. IBS may also cause problems such as arthritis, inflammation of the eye, liver disease, and osteoporosis. This disease causes inflammation and sores, called ulcers, in the lining of the rectum and colon.
Ischemic is a form of vasculitis that results from inflammation and ischemia of colonic mucosa, which causes rectal bleeding and abdominal pain. Treatment for collagenous and lymphocytic varies depending on the symptoms and severity of the case. People with ulcerative colitis have abnormalities of the immune system, but doctors do not know whether these abnormalities are a cause or a result of the disease. Pseudomembranous usually presents with profuse watery or mucoid diarrhea, tenesmus, fever, abdominal cramps, and tenderness usually within one week of antibiotic therapy.
After age 50 a regular colonoscopy is recommended for early detection of colon cancer unless the patient has increased risk of cancer and then more frequent examinations may be prescribed by the patients doctor.
