Lactase is a common enzyme that exists in the small intestine of
many people. It is essential for digestion of lactose, the naturally
occurring sugar in milk.
However, not everyone produces
enough lactase, resulting in difficulty or even inability to digest
milk. Those who are "lactose intolerant" often suffer from symptoms
including stomach cramps, gas, and diarrhea. While lactose
intolerance can be diagnosed by a doctor, a home test for lactose
intolerance may also work. Simply drink two cups of milk on an empty
stomach and pay attention to see if any gastrointestinal symptoms
develop over the next five hours. Repeat this test the next day
using several ounces of cheese instead of milk. If gastrointestinal
symptoms arise from consuming milk but not cheese, then it is likely
the person is suffering lactose intolerance. However if symptoms
occur when consuming milk and cheese, then it is more likely the
individual has an allergy to dairy products rather than having
lactose intolerance.
Oddly enough lactose intolerance in
quite common. World wide only one-third of all people have the
ability to digest lactose throughout adulthood. Most individuals of
Asian, African, and Native American descent are lactose intolerant.
In addition, half of Hispanics and about 20 percent of Caucasians do
not produce lactase as adults.
Benefits of
Lactase
Lactase has been used in connection with the
following conditions in lactose intolerant individuals: diarrhea,
indigestion, heartburn, and irritable bowel
syndrome.
Dosage and
Administration
There are a number of ways to deal
with lactose intolerance. Lactose-reduced milk is available or
lactase drops can easily be added to regular milk to reduce lactose
levels. Lactase drops, capsules, and tablets can also be taken
directly as needed.
