Nausea is an uncomfortable but non-painful feeling in the back of your throat, chest, or upper stomach. Nausea causes a queasy, unsettled feeling that can make you want to throw up (vomit). Everyone gets this feeling from time to time, especially if you have a stomach bug, are pregnant, or have food poisoning.
When you have chronic nausea, you feel like this all the time. People with chronic nausea feel nauseous at the smell of certain foods, or when they experience certain motions, hunger, or stress. Some people experience nausea even when they are sleeping.
Chronic nausea can include symptoms that are difficult to describe. Even more, diagnostic tests for many people come back normal. At Stanford Health Care, our experts have years of experience researching and caring for people with this condition. Learn more about our General Gastroenterology Clinic.
