What is the difference between saying someone is lactose intolerant versus saying someone is lactose non-tolerant?

Answer by  saku (13)

Someone who is lactose intolerant is unable to process milk in their system. If milk is consumed, the person becomes ill with a stomach ache and it is a very uncomfortable experience. Thus, they become intolerant. "Lactose non-tolerant" is not a correct term. Non tolerant is the same as intolerant.

From my understanding, a person who is lactose intolerant is one who has difficulty digesting dairy products. The person will become sick, have "bathroom" issues, and stomach cramps. Someone who is non-tolerant, cannot handle dairy at all. One would have an adverse, potentially fatal reaction to dairy products.

The difference is simply that 'Lactose Intolerant' is the correct way to say it. Lactos Non-Tolerant is not a disease, it's not even a real word. It would mean the same thing if 'non-tolerant' was actually a word.
