General meaning:
Lactose intolerance is results of an inability to digest or to metabolize lactose.
Flow:
Note that the common definition for "lactose intolerance" excludes infants. Virtually all human infants (indeed all mammal infants) are able to digest lactose, as it is a key ingredient in gaining sustenance from their mother. Infants not able to digest lactose are much more rare (and is a serious condition).
Normally, mammals lose the ability to digest lactose shortly after entering childhood (in humans, somewhere between 3 and 5). However, a mutation in certain human populations somewhere around 20,000 BCE enabled those people to continue to consume milk for their entire life. So, in reality, "lactose tolerance" is the genetic aberration (though, a beneficial one).
Lactose Intolerant means that your body is unable to metabolize, or tolerate, a sugar found in milk and other dairy products called Lactose. It is caused by a lack of lactase, the enzyme required to break down lactose in the digestive system, and results in symptoms including abdominal pain, bloating, flatulence, diarrhea, nausea and acid reflux.

Lactose intolerance is the normal state of most adult mammals. After weaning, mammals normally stop producing lactase, the enzyme that breaks down the sugar in milk.
Some human populations, mostly those of northern European descent, have a genetic mutation that causes lactase persistence, which allows them to continue to digest lactose into adulthood.
Lactose Intolerance occurs in the digestive system.
A gastroenterologist treats lactose intolerance and ulcers.
Galactose is involved with lactose intolerance, but is not responsible for lactose intolerance. The enzyme that is missing or is not found in great enough quantities in the body, lactase, is responsible for not breaking down lactose. This is how the intolerance comes about. The body cannot properly break down lactose without the enzyme lactase present.
Lactose intolerance occurs when the digestive system is no longer able to metabolise the sugars (lactose) found in dairy products through producing insufficient amounts of an enzyme called lactase.
No
The Basques. They are virtually free of lactose intolerance.
intestinal gas and bloating after dairy products are consumed
Lactose intolerance results from an inability in the small entrails to digest lactose. You can get so many carbohydrates or sugar in milk what's called lactose. You should avoid this.
