Technically, the words nauseous and nauseating describe something that makes you feel sick, and the words nauseated and queasy describe the way you feel - like your stomach is uncomfortable and you might vomit:

I felt nauseated every morning during the first few months of pregnancy.

However, today many people say "I feel nauseous" - so this use of nauseous to mean the feeling is becoming more acceptable. Nauseating is still used to describe the thing causing the feeling.
Nausea is the noun form (the other words are adjectives). It is often used when describing symptoms:
