When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion. Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion.
Here are five common misconceptions about digestive diseases:
1. Spicy foods cause ulcers.
The truth is, almost all stomach ulcers are caused either by infection with a bacterium called Helicobacter pylori (H. pylori) or by use of pain medications such as aspirin, ibuprofen, or naproxen, the so-called nonsteroidal anti-inflammatory drugs. Most H. pylori-related ulcers can be cured with antibiotics. NSAID-induced ulcers can be cured with time, stomach-protective medications, antacids and avoidance of NSAIDs. Spicy food and stress may aggravate ulcer symptoms in some people, but they do not cause ulcers.
2. Bowel regularity means a bowel movement every day.
The frequency of bowel movements among normal, healthy people varies from three a day to three a week, and some perfectly healthy people fall outside both ends of this range.
3. Irritable bowel syndrome is a not a disease.
Irritable bowel syndrome is a disease, although it is also called a functional disorder. Irritable bowel syndrome involves a problem in how the muscles in the intestines work and pain perception in the bowel. It is characterized by gas, abdominal pain, and diarrhea or constipation, or both. Although the syndrome can cause considerable pain and discomfort, it does not damage the digestive tract as organic diseases do. Also, irritable bowel syndrome does not lead to more serious digestive diseases later, such as cancer.
4. Cirrhosis sole cause is alcoholism.
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 half of cirrhosis cases. The remaining cases are from 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. In adults, cirrhosis can also be caused by nonalcoholic steatohepatitis (NASH), which is becoming the most common liver disease in the United States, affecting 2 to 5 percent of Americans
5. Diverticulosis is a serious but uncommon problem.
Actually, the majority of Americans over age 60 have diverticulosis, but only a small percentage have symptoms or complications. Diverticulosis is a condition in which little sacs or out-pouchings called diverticula develop in the wall of the colon. These sacs tend to appear and increase in number with age. Most people have no symptoms and learn that they have diverticula after an X-ray or intestinal examination. Less than 10 percent of people with diverticulosis ever develop complications such as infection (diverticulitis), bleeding, or perforation of the colon.

Did you know?
You get a new stomach lining every three to four days. If you didn’t, the strong acids your stomach uses to digest food would also digest your stomach.
