Effects and Diagnoses of Lactose intolerance

Lactose intolerance : The inability to digest significant amount of lactose is known as lactose intolerance. The inability of the cells in producing sufficient amount of lactose causes its shortage. Function of lactose is to break down lactose into simple forms that can easily be absorbed into bloodstream in digestion process. Lactose when reaches into digestive system, the lactose enzyme breaks down lactose into glucose and glactose. There are three types of lactose intolerance.

1. Primary lactose intolerance : In primary lactose intolerance, the body starts to produce less amount of lactose after two years of age. The production of less lactose wholly depends on an individual’s racial or ethical background. It is permanent condition and determined genetically.

2. Secondary lactose intolerance : This type of lactose intolerance is temporary in nature which is caused by a disease or some medication. It damages the lining of small intestine where lactose is normally produced. As diseases passes, secondary lactose intolerance also tends to disappear.

3. Congenital lactose intolerance : This condition is found rarely because in it lactose enzyme is completely absent at the time of birth. The complete avoidance of lactose is required in this condition.

Diagnosis of lactose intolerance : Different test like lactose tolerance test and hydrogen breath test are done to measure the absorption of lactose into the digestive system. In lactose tolerance test subject is asked to drink a liquid that contains lactose. Through several blood samples taken over the period of two hours, blood glucose level is measured. Incomplete absorption of lactose confirms the diagnosis of lactose intolerance.

Hydrogen in breath is measured in hydrogen breath test. Bacteria in colon fermented undigested lactose which produces hydrogen. The hydrogen is carried through the blood stream to the lungs and is exhaled. In this test subject consumes beverage containing lactose and breath into a machine that measures hydrogen in the breath.

Diet recommendation : The major source of calcium is milk and dairy products. Yogurt with active clutter may tolerate by many people because in making yogurt bacterial clutter produces lactose enzyme required for digestion. Cheese can also be tolerated by lactose-intolerance people because most of the lactose is removed when cheese is made.

Lactose intolerant people can get required amount of calcium from dark green leafy vegetables like broccoli, turnip and kale. Salmon, herring fish with edible bones are also good source of calcium.
