Procedures & Treatments

Lactose Intolerance Test

A breath hydrogen monitor is used to perform a lactose intolerance breath test. Lactose intolerance is the inability to digest lactose, the sugar found in milk. It causes cramping, bloating, gas or diarrhea any time dairy products are consumed. Lactose intolerance occurs due to the body’s lack of lactase, an enzyme normally produced by the small intestine.

The lactose intolerance breath test is a quick way to discover if a patient has lactose intolerance. Studies indicate that as many as 70% of patients that have lactose intolerance do not relate their symptoms to lactose ingestion. They may even mislead their physicians by denying a connection of their symptoms to their diet. The lactose intolerance breath test is done in the doctor’s office and only requires five minutes of the patient’s time. This hydrogen breath test is easy to use, non-invasive and gives the physician immediate results. Lactose intolerance is often recognized for the first time in older patients. They may have endured gas and other symptoms for years without connecting the symptoms to their diet. If you suspect you or your patient is suffering from lactose intolerance, please call us to set up this test.

Fructose Intolerance Test

Unexplained bloating, gas, and distension are common GI complaints. While much attention has been paid to lactose intolerance as a potential cause, fructose intolerance has received relatively little attention.

The fructose intolerance breath test measures the levels of hydrogen in the breath after a patient has ingested a high fructose drink. Often, patients who do not have lactose intolerance but who have gastrointestinal complaints are suffering from fructose intolerance. This test is easily performed in our office. After fasting overnight, the patient’s baseline hydrogen breath levels are measured. After ingesting a high fructose drink, the patient breath is tested again. This test takes only a few minutes, it’s non-invasive and gives the physician immediate results. If you suspect you or your patient may be fructose intolerant, please call us to set up this test.

Bacterial Overgrowth

Bacterial overgrowth syndrome (BOS) is a term that describes clinical manifestations that occur when the normally low number of bacteria that inhabit parts of the intestinal tract significantly increases or becomes overtaken by other pathogens.

The upper intestinal tract was once thought to be a sterile environment; however, low concentrations of various bacteria are now widely accepted to live within or attached to its surface. These bacteria are thought to be present from the time of birth and through adulthood. This relationship is thought to be vital for normal digestive processes, immunity, and intestinal development. Sometimes there is an overgrowth of bacteria in the intestinal tract and this causes gastrointestinal problems for the patient.

The bacterial overgrowth breath test is non-invasive and easy for the patient. After fasting overnight, the patient will be asked to ingest a lactulose drink or enulose syrup. He/she will then be tested every 15 minutes during the next 1 hours to determine if there is bacterial overgrowth present. This test is easy, performed in our office, and gives immediate results. Please call us if you need to schedule this test for your patient.
