Nausea is an uncomfortable situation that causes the person to feel like they want to vomit. A nauseous feeling can quickly come and go or it can last for a long period of time. When a person feels nauseous, his brain tells his body that he is feeling ill and needs to expel the contents of their stomach. The brain signals the stomach to contract and physically throw up the stomach’s contents. Nausea can arise in a person for a variety of reasons.
