    Gallstones

    Normally a balance of bile salts, lecithin and cholesterol keep gallstones from forming. If there are abnormally high levels of bile salts or, more commonly, cholesterol, stones can form. Symptoms usually occur when the stones block one of the biliary ducts or gallstones may be discovered upon routine x-ray or abdominal CT study.

    Gallstones are hard, pebble-like deposits that form inside the gallbladder. Gallstones may be as small as a grain of sand or as large as a golf ball.

    Gastritis

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    Gastritis occurs when the lining of the stomach becomes inflamed or swollen. Gastritis can last for only a short time (acute gastritis), or linger for months to years (chronic gastritis).

    Gastroesophageal reflux disease

    A band of muscle fibers, the lower esophageal sphincter, closes off the esophagus from the stomach. If the sphincter does not close properly, food and liquid can move backward into the esophagus and cause heartburn and other symptoms known as gastroesophageal disease (GERD). To alleviate symptoms dietary changes and medications are prescribed. For a patient who has persistent symptoms despite medical treatment, an anti-reflux operation may be an option.

    Gastroesophageal reflux disease (GERD) is a condition in which the stomach contents (food or liquid) leak backwards from the stomach into the esophagus (the tube from the mouth to the stomach). This action can irritate the esophagus, causing heartburn and other symptoms.In gastroesophageal reflux ...

    Gastrointestinal fistula

    The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.

    A gastrointestinal fistula is an abnormal opening that allows the contents of the stomach or intestines to leak. If it leaks through to a part of the intestines, it is called an entero-enteral fistula. If it leaks to through to the skin, it is called an enterocutaneous fistula.

    Gastrointestinal perforation

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    Gastrointestinal perforation is a hole that develops through the whole wall of the esophagus, stomach, small intestine, large bowel, rectum, or gallbladder. This condition is a medical emergency.

    Gastroparesis

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    Gastroparesis is a condition that reduces the ability of the stomach to empty its contents. It does not involve a blockage (obstruction).

    Giardia infection

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    Giardiasis is an infection of the small intestine caused by a tiny parasite called Giardia lamblia.

    Gilbert's disease

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    Gilbert’s disease is a common disorder passed down through families. It affects the way bilirubin is processed by the liver, and causes jaundice.
