Digestive Function Tests

Function studies are performed to see how the various parts of the body "work" … or function. For example, are nutrients being properly absorbed by the body?

Ano-rectal manometry measures pressures of the anal sphincter muscles. It also measures how well a person feels different sensations of fullness in the rectum.

Esophageal manometry is useful in documenting abnormalities in the mid-lower regions of the esophagus in patients with Gastro Esophageal Reflux Disease (GERD).

Gastric emptying studies help to evaluate how quickly food is emptied into the intestine via the channel that leaves the stomach before entering the duodenum.

A gastroduodenal manometry checks pressure changes that occur within the stomach and upper intestine during digestion.

Blood tests, X-ray studies, stool studies, xylose absorption, and pancreatic function tests may all be used when symptoms of malapsorption are present.

Intra-esophageal detects episodes of Gastro Esophageal Reflux Disease (GERD). Measurements can show when reflux occurs, under what circumstances, and how often.

Pudendal nerve studies evaluate the nerve to the anal sphincter muscles and measures how long it takes those muscles to contract after the nerve is stimulated.

A transit time X-ray measures the time it takes for food to go through the colon. The person takes special capsules by mouth twice a day for five days.
