Learn About FGIMDs

There are over two dozen chronic functional gastrointestinal and motility disorders (FGIMDs), ranging from mild to debilitating to life-threatening and even fatal. Below is a listing of some conditions that represent FGIMDs.

Upper GI Conditions

Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease, or GERD, is a common disorder. Gastroesophageal refers to the stomach and the esophagus. Reflux refers to the back-flow of acidic or non-acidic stomach contents into the esophagus. GERD symptoms result from repeated or prolonged exposure of the lining of the esophagus to contents from the stomach. Symptoms vary from person to person. Common GERD symptoms are heartburn and regurgitation (refluxed material into the mouth). Sometimes there are no obvious symptoms.   Learn More


Dyspepsia is a term used to describe one or more symptoms including a feeling of fullness during a meal, uncomfortable fullness after a meal, and burning or pain in the upper abdomen.  Learn More

Gastroparesis (Delayed Gastric Emptying)

Gastroparesis is a disorder in which symptoms occur and the stomach empties very slowly. It most often occurs when the nerves to the stomach are damaged or don't work properly. Most often the cause cannot be found and the disorder is termed idiopathic gastroparesis. Diabetes is the most common known cause of gastroparesis. The disorder may also occur after stomach surgery for other conditions. Some medications and other illnesses may also cause gastroparesis.   Learn More

Dumping Syndrome (Rapid Gastric Emptying) 

Dumping syndrome (rapid gastric emptying) occurs when undigested food empties too quickly from the stomach into the small intestine. This food is not broken down enough for the small intestine to efficiently absorb nutrients. Dumping syndrome is most commonly seen after stomach surgery such as fundoplication, gastric bypass, or removal of all or part of the stomach, usually for ulcer disease.  Learn More

Cyclic Vomiting Syndrome (CVS) 

Cyclic vomiting syndrome (CVS) is a disorder with recurrent episodes of severe nausea and vomiting interspersed with symptom free periods. It can occur in both children and adults.  Learn More

Lower GI Conditions

Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a disorder involving the way nerves and muscles are working. In the doctor's office nothing abnormal is seen on tests. The bowels look fine. Yet there is pain, discomfort, and other symptoms that won't go away or keep coming back. Certain signs and symptoms are the basis for identifying, or diagnosing, IBS.  Learn More

Fecal (Bowel) Incontinence (FI) 

Many otherwise healthy, active people suffer from incontinence or loss of bowel control. Fecal incontinence (also called bowel incontinence) strikes people of all ages. It involves the accidental loss of solid or liquid stool. Leakage of intestinal gas without loss of stool may also impair a person's quality of life and call for treatment.  Learn More

Hirschsprung's Disease (HD)

Hirschsprung's disease is a rare condition that people are born with. People born with Hirschsprung's disease are missing the nerve cells within the wall of their colon or rectum. These cells are responsible for the normal wave-like motion of the bowel. When they are missing the stool stops and an obstruction occurs. The length of affected bowel varies.  Learn More

Short Bowel Syndrome

Short bowel syndrome is a group of problems related to poor absorption of nutrients. It typically occurs in people who have had half or more of their small intestine removed. The small intestine is where most digestion of food and absorption of nutrients occur. People with short bowel syndrome cannot absorb enough water, vitamins, and other nutrients from food to sustain life.  Learn More

Chronic Intestinal Pseudo-Obstruction (CIP)

Chronic intestinal pseudo-obstruction (CIP) is a rare disorder. Symptoms are like those caused by a bowel obstruction, or blockage. But when the intestines are examined, no blockage is found. The symptoms are caused by a problem in how the muscles and nerves in the intestines work. That affects the movement of material through the intestines. In some persons, pseudo-obstruction may progress throughout the digestive tract.  Learn More
