Portland is a city located in the Northwestern United States, near the confluence of the Willamette and Columbia rivers in the state of Oregon. It has been referred to as the most environmentally friendly or "green" city in the United States, and the 2nd most in the world. The city and region are noted for strong land-use planning and investment in light rail, supported by Metro, a distinctive regional-government. Portland is known for its large number of microbreweries and microdistilleries, and its coffee fanaticism.

Lactose Tolerance Test

What is the lactose tolerance test?

The lactose tolerance test is a test for diagnosing an intolerance of ingested lactose. Lactose intolerance is a genetic condition in which individuals are unable to digest and absorb the lactose sugar in cow's milk.

What is lactose intolerance?

Lactose intolerance is the inability to digest the sugar in milk, lactose. Milk is an important source of nutrition for children and even some adults. With normal lactose tolerance, all of the lactose is broken down (digested) in the intestine by an enzyme into two smaller sugars (galactose and glucose) which then are absorbed into the body. As a result, normally no lactose reaches the colon.

On the other hand, in individuals with lactose intolerance who lack the intestinal enzyme that breaks down the lactose, the ingested lactose is neither digested nor absorbed in the small intestine and reaches the colon where it is used by the bacteria in the colon. The bacteria produce chemicals that cause diarrhea, and also produce gas. Abdominal pain also may occur.

How is the lactose tolerance test done?

The lactose tolerance test requires an individual to drink a liquid that contains lactose. In the small intestine among lactose tolerant individuals, the ingested lactose is split into galactose and glucose which then are absorbed from the intestine and go into the blood. Several blood samples are taken over a two hour period following the ingestion of the lactose to measure the blood glucose level. If lactose tolerance is normal, the glucose level in the blood rises due to the absorption of glucose from the intestine. If there is lactose intolerance, the glucose level does not rise.

What other tests can detect lactose intolerance?

Other tests used to detect lactose intolerance include the lactose hydrogen breath test and stool acidity te...

Colonoscopy »

What is colonoscopy?

Colonoscopy is a procedure that enables an examiner (usually a gastroenterologist) to evaluate the inside of the colon (large intestine or large bowel). The colonoscope is a four foot long, flexible tube about the thickness of a finger with a camera and a source of light at its tip. The tip of the colonoscope is inserted into the anus and then is advanced slowly, under visual control, into the rectum and through the colon usually as far as the cecum, which is the first part of the colon.

Why is colonoscopy done?

Colonoscopy may be done for a variety of reasons. Most often it is done to investigate the cause of blood in the stool, abdominal pain, diarrhea, a change in bowel habit, or an abnormality found on colonic X-rays or a computerized axial tomography (CT) scan. Individuals with a previous history of polyps or colon cancer and certain individuals with a family history of some types of non-colonic canc...
