Why do people get Lactose Intolorance?

Question

I'm Lactose Intolorant

Answer 1

Lactose intolerance is caused by the inability of the digestive system to break down lactose into glucose. We also know that the protein (enzyme) responsible to break down lactose into glucose is called lactase. Therefore, the lack of lactase causes lactose intolerance. However, different persons may have different amounts of lactase produced. For instance Peter may be producing just enough lactase to cope with a glass of milk in the morning before suffering any effects while Jane is not even able to have a lick of ice-cream because it distresses her. Some of the causes of lactose intolerance are known. The production of the enzyme lactase can be hindered by certain digestive diseases and injuries to the small intestine. In some cases, children are born without the ability to produce lactase. However, in most cases lactase deficiency develops naturally over time when after about the age of 2 years, the body begins to produce less lactase. Interestingly, most people do not experience symptoms until they reach an older age.

Answer 2

It is genetic. People that are lactose intolerant don't have the
genes or have defective ones for proper production of the enzyme "Lactase". This enzyme is required for the breaking down of lactose into glucose during the digestive process.
Some people with lactose intolerance can produce small amounts of lactase, while
others can't produce the enzyme at all.
You can take lactose supplements in pill/capsule form or you
can get milk that has the enzyme added to it.

Answer 3

Because humans, like all mammals, should not be drinking any milk once they've been weaned from their mothers-- certainly not the milk from another animal. It's not natural. Your digestive system is not able to break down completely the sugar called lactose found in animal milk.

Answer 4

Their body cannot break down the milk protein lactose. To break it down the body uses the enzyme lactase, and when they body cannot make lactase you develop lactose intolerance

Answer 5

Cow's milk isn't very healthy for humans in general, but for some their bodies completely reject it. I have known more people of African-American decent than white people who tend to have that reaction too. I'm not sure why that would be.

Answer 6

Genetics.

Answer 7

It's because your body doesn't produce enough lactase enzyme to break down dairy products.

Answer 8

It's an allergy of sorts. Why do people get warts? It happens.

Answer 9

i think after a while your stomach weekens

Answer 10

its either random or its inherated.....
