Diseases of the Digestive System - Gallbladder disease
The biliary tract is very often plagued by the presence of stones in the gallbladder or one of the bile ducts. Gallstones are mostly a mixture of calcium carbonate, cholesterol, and bile salts, and can occur either as one large stone or a few smaller ones.
When fats from the daily diet enter the small intestines, the concentrated bile from the gallbladder is poured into the duodenum via the bile ducts. Bile is necessary if fats are to be digested and absorbed. If stones are present in the biliary tract, the gallbladder will contract, but little or no bile will reach the fats in the small bowel.
A sharp pain to the right of the stomach is usually the first warning sign of gallstones, especially if the pain is felt soon after a meal of fatty foods—eggs, pork, mayonnaise, or fried foods. The presence of stones very often causes inflammation of the gallbladder and such symptoms as occasional diarrhea and nausea with vomiting and belching. The abdominal area near the gallbladder is usually very tender.
Untreated gallbladder disease leads to several possible complications. The obstructed bile pigments may be recirculated in the bloodstream, causing jaundice. Obstruction of the ducts causes increased pressure and may also result in perforation of the gallbladder or ducts. Acute inflammation of the biliary tract is always a possibility due to the irritation caused by the concentrated bile.
A gallbladder that is full of stones or badly diseased must be surgically removed for the patient's health to improve. In milder cases, other treatment and special diet can prevent attacks.
