Microscopic Colitis (Collagenous Colitis / Lymphocytic Colitis)

Thirteen patients with microscopic colitis were treated with 8 chewable 262mg bismuth subsalicylate tablets per day for 8 weeks. Twelve patients completed the trial. Eleven patients had a resolution of their diarrhea and a reduction in fecal weight. The average time to respond was 2 weeks. In 9 patients colitis resolved. Post-treatment follow-up for 7-28 months showed that the 9 patients remained well without treatment, 2 were well but still required treatment and 1 had continued diarrhea.

Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.


A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach’s mucous lining must constantly regenerate itself.


Excessive discharge of contents of bowel.


Lesion on the skin or mucous membrane.


Microscopic germs. Some bacteria are "harmful" and can cause disease, while other "friendly" bacteria protect the body from harmful invading organisms.

Helicobacter Pylori

H. pylori is a bacterium that is found in the stomach which, along with acid secretion, damages stomach and duodenal tissue, causing inflammation and peptic ulcers. Although most people will never have symptoms or problems related to the infection, they may include: dull, 'gnawing' pain which may occur 2-3 hours after a meal, come and go for several days or weeks, occur in the middle of the night when the stomach is empty and be relieved by eating; loss of weight; loss of appetite; bloating; burping; nausea; vomiting.


(mg): 1/1,000 of a gram by weight.


A disease characterized by an increased blood uric acid level and sudden onset of episodes of acute arthritis.

Diabetes Mellitus

A disease with increased blood glucose levels due to lack or ineffectiveness of insulin. Diabetes is found in two forms; insulin-dependent diabetes (juvenile-onset) and non-insulin-dependent (adult-onset). Symptoms include increased thirst; increased urination; weight loss in spite of increased appetite; fatigue; nausea; vomiting; frequent infections including bladder, vaginal, and skin; blurred vision; impotence in men; bad breath; cessation of menses; diminished skin fullness. Other symptoms include bleeding gums; ear noise/buzzing; diarrhea; depression; confusion.

Hypersensitivity caused by exposure to a particular antigen (allergen), resulting in an increased reactivity to that antigen on subsequent exposure, sometimes with harmful immunologic consequences.


Commonly known as hives, urticaria is one of the most common dermatological conditions seen by allergists. Urticaria is not just an allergic disease, however. It can be caused by metabolic diseases, medications, infectious diseases, autoimmune disease, or physical sensitivity. Traditional allergies to foods or medications as well as viral illness are frequent causes of acute urticaria which usually lasts only a few hours but may last up to 6 weeks. Chronic urticaria (lasting more than 6 weeks) is more complex, given the vast number of potential triggers. Symptoms include sudden onset; initial itching; then swelling of the surface of the skin into red or skin-colored welts (wheals) with clearly defined edges; welts turn white on touching; new welts develop when the skin is scratched; usually disappear within minutes or hours. Welts enlarge, change shape, spread or join together to form large flat raised areas.


Difficult, incomplete, or infrequent evacuation of dry, hardened feces from the bowels.
