Lactose intolerance is caused by your digestive system not being able to digest the natural sugar known as Lactose.

When your bodies digestive system cannot digest that Lactose then it leads to lactose intolerance and causes stomach pain, abdominal pain and sometimes vomiting and farting as well.

Lactose intolerance occurs when the bodies small intestine doesn't produce enough of an enzyme (lactase) to digest the milk sugar (lactose).

Normally, lactase turns the milk sugar into two simple sugars which are glucose and galactose at which they are absorbed into the bloodstream through the intestinal lining.

If your stomach hurts after drinking milk then you're likely lactose intolerant.

Most milk contains lactose which some people are intolerant too or have sort of like an allergy to the milk that contains lactose.

So if your stomach hurts after drinking milk then try some lactose free milk and see if that does not hurt your stomach and if it does not then you're lactose intolerant.

Lactose is basically a type of natural sugar found in milk in most mammals including humans and some people are just intolerant to that.

Lactose intolerance is not as serious as a regular dairy or milk allergy but the lactose intolerance can cause stomach pain, bloating etc.

When you're lactose intolerant your body has a harder time digesting the lactose or sugar found in the milk and dairy products which makes your stomach hurt.

Symptoms of Lactose Intolerance are stomach pain, farting, bloating, gas buildup in your stomach and abdominal cramping.

Lactose Intolerance is the inability to fully digest sugar (lactose) in dairy products.

Lactose intolerance is usually caused by a deficiency of an enzyme in the body called lactase.

Symptoms of lactose intolerance can include abdominal cramps, bloating, and diarrhea.

Treatment for lactose intolerance focuses on avoidance of dairy products, use of lactose-free products, or the use of lactase supplements.

The 4 types of lactose intolerance are.

Primary lactose intolerance (normal result of aging) This is the most common type of lactose intolerance.
Secondary lactose intolerance (due to illness or injury).
Congenital or developmental lactose intolerance (being born with the condition).
Developmental lactose intolerance.

You can suddenly become lactose intolerant even though you were able to eat and drink dairy products before.

My husband used to be able to drink milk and eat dairy products as a kid and up until he turned 25 years old.

Then suddenly when he turned 25 years old he started having stomach aches when drinking milk and eating certain dairy products.

He then went to the doctor and got tested and the doctor said that he was now lactose intolerant.

So if you were previously able to drink milk and eat dairy products and suddenly the milk and other dairy products give you stomach aches or other stomach problems then you're probably now lactose intolerant.

Some people are lactose intolerant as a kid and then lactose intolerant for life and some people develop lactose intolerance later on in life.
