Most people do not have symptoms and would not know that they had diverticula unless x-ray or intestinal examination were done. Inflammatory bowel disease is caused by psychological problems. Inflammatory bowel disease is the general name for two diseases that cause inflammation in the intestines, Crohn's disease and ulcerative colitis. The cause of the disease is unknown, but researchers speculate that it may be a virus or bacteria interacting with the body's immune system. There is no evidence to support the theory that inflammatory bowel disease is caused by tension, anxiety, or other psychological factors or disorders.
Alcoholism is just one of many causes of cirrhosis.
Cirrhosis is scarring and decreased function of the liver. In the United States, alcohol causes less than one-half of cirrhosis cases. The remaining cases are from other diseases that cause liver damage. For example, in children, cirrhosis may result from cystic fibrosis, alpha-1 antitrypsin deficiency, biliary atresia, glycogen storage disease, and other rare diseases. In adults, cirrhosis may be caused by hepatitis B or C, primary biliary cirrhosis, diseases of abnormal storage of metals like iron or copper in the body, severe reactions to prescription drugs, or injury to the ducts that drain bile from the liver.
