What is lactose intolerance?

Lactose intolerance is the inability to spend lactose -containing dairy products, especially milk. Lactose is sugar that is distributed in the body with an enzyme called lactase . Lactase is usually excreted with cells lining the small intestine and decomposes lactose into glucose, which is then absorbed into the bloodstream. When lactase is insufficient, undigested lactose begins to ferment in the lower intestines. This can cause physical discomfort in the range of flatulence, nausea and gas to convulsions and diarrhea.

while it is rare for children to be born without the ability to produce lactase, after about 2 years the production of this enzyme is shrinking. It is therefore not unusual that so many adults are influenced by lactose intolerance to different degrees. The severity of physical discomfort will depend on how much lactase a person produces in relation to how much lactose is consumed. For example, one glass of milk may not cause any person's problems, even if two glasses could. In any case, this condition affects fromA snake of 30–50 million Americans, with 90% of Asian Americans affected and at least 75% of African American and American Indians.

There are common tests that a doctor can perform to see if you are intolerant lactose. Lactose -rich liquid is consumed after a short fast. The doctor could then draw several blood samples for 2 hours to see how the body spends lactose. If it is cleaned properly, it should be converted to glucose that will be found blood. Or, if you decide to test for breathing hydrogen, your breath will be tested for the presence of hydrogen. Hydrogen is usually not present in the breath except very small quantities, but the fermentation of lactose will produce a larger amount of hydrogen that will be detected and measured.

If a very small child or a child needs to be tested for lactose intolerance, an alternative test that controls acidity in the stool is available. BearRacing lactose creates lactic acid and other fatty acids found in the stool sample.

lactose intolerance is controlled by diet. Often a small amount of lactose is fine and it is simply a matter of finding your level of tolerance and limiting food containing lactose. Lactase enzymes are also available on the counter. Enzymes that take lactose meals decompose lactose for your body. Dairy products with reduced lactose are also option.

people who do not eat lactose products can worry about calcium intake. Many non -dairy foods have a high calcium content such as green vegetables such as Boccoli and Kale. Some fish types also have a high calcium content.
