Please visit the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) website for a full A-to-Z list of GI diseases and disorders.

Pancreatitis

Pancreatitis is inflammation of the pancreas. The pancreas is a large gland behind the stomach and close to the duodenum—the first part of the small intestine.

Lactose Intolerance

Lactose intolerance is the inability or insufficient ability to digest lactose, a sugar found in milk and milk products.

Irritable Bowel Syndrome

Irritable bowel syndrome is a disorder characterized most commonly by cramping, abdominal pain, bloating, constipation, and diarrhea.

Hepatitis

Autoimmune hepatitis is a disease in which the body’s immune system attacks liver cells. This immune response causes inflammation of the liver, also called hepatitis.

Hemorrhoids

Hemorrhoids are swollen and inflamed veins around the anus or in the lower rectum.

Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease (GERD) is a more serious form of gastroesophageal reflux (GER), which is common. GER occurs when the lower esophageal sphincter (LES) opens spontaneously, for varying periods of time, or does not close properly and stomach contents rise up into the esophagus.

Gastritis

Gastritis is a condition in which the stomach lining—known as the mucosa—is inflamed.

Gallstones

Gallstones are small, pebble-like substances that develop in the gallbladder. The gallbladder is a small, pear-shaped sac located below your liver in the right upper abdomen. Gallstones form when liquid stored in the gallbladder hardens into pieces of stone-like material.

Diarrhea

Diarrhea is loose, watery stools. Having diarrhea means passing loose stools three or more times a day. Acute diarrhea is a common problem that usually lasts 1 or 2 days and goes away on its own.

Crohn’s Disease

Crohn’s disease is a disease that causes inflammation, or swelling, and irritation of any part of the digestive tract—also called the gastrointestinal (GI) tract. The part most commonly affected is the end part of the small intestine, called the ileum.
