Document Summary
Heartburn occurs when stomach contents including acid moves from the stomach up into the esophagus through the sphincter. Gerd = gastroesophageal reflux disease (gastro means stomach) = recurring heartburn: can happen if someone doesn"t chew properly between swallowing, can happen to obese people, quite common (about 1/3 of north american population) Symptoms and complications: burning sensation, pain, bleeding, ulcers, can- cer. Gastrointestinal tract lining is normally protected from acid and pepsin by mucus. Ulcers occur in esophagus, stomach, or small intestine from damage to lining by stomach acid and pepsin. : bacterium helicobacter pylori (h. pylori), aspirin, and other pain: h. pylori is the most common cause. Solid material accumulates in the gall bladder and bile ducts and blocks bile. After gall bladder removal, bile drips into the small intestine rather than be- ing consumed when fat is consumed, so fat content of meals needs to be re- duced.
