I can understand your worry about your husband's digestion problems. The pancreas is an important body organ that produces vital digestive enzymes and supplies insulin to deal with sugar in the blood. Johns Hopkins Medicine in Baltimore, Maryland, reports that there are 25 digestive disorders with some having the same symtoms. Johns Hopkins White Paper on Digestive Disorders reads the the chief cause of pancreasitis is drinking. An affected pancreas may not produce the neccessary digestive enzymes required, and may affect the way the pancreas deals with sugar in the blood. The appointment with a Gastroenterologist will be able to pinpoint the problems and pain your husband suffers. Bowels that float with mucus is another symptom of a disorder called Irriable Bowel Syndrome, and maybe more. In the meantime, I can give to you a governmet website that lists, explains, give symptoms, and cures for digestive problems from A to Z. Go to http://digestive.niddk.nih.gov. Click on the homepage on Digestive, and the next page lists the digestive disorders. You can gather all the information you need to ask the Gastroenterologist.
