Nauséeux vs. barbouillé
In French, the words nauséeux and barbouillé both refer to stomach discomfort, but they have distinct differences in intensity, usage, and formality. Choosing the correct word depends on how severe the sickness is and the context of the situation.
Nauséeux
The word nauséeux is a strong, slightly formal or medical term meaning nauseous or nauseating. It is used to describe a severe urge to vomit or to describe something external, like a smell, that induces nausea.

(She refused the meal because she felt very nauseous.)
Barbouillé
The word barbouillé is a casual, everyday term meaning queasy or having an upset stomach. It describes a mild, general discomfort that does not necessarily lead to vomiting, often caused by eating too much rich food, mild motion sickness, or waking up feeling slightly off.

Summary
To summarize, use nauséeux when describing a strong, medical, or literal urge to vomit, as well as things that cause that feeling. Use barbouillé in everyday conversation to describe a mild upset stomach or queasiness, especially after overeating or experiencing minor motion sickness.
