What is the relationship between migraines and nausea?

Migraines are often accompanied by nausea and/or vomiting. In fact, nausea is one of the most common symptoms of migraines, occurring in up to 80% of cases. The nausea associated with migraines is thought to be caused by the release of certain chemicals in the brain during a migraine attack, which can irritate the stomach and cause nausea and vomiting. Additionally, the pain and other symptoms of a migraine can also contribute to nausea. Nausea can be a very distressing symptom of migraines, and can make it difficult for people to go about their daily activities. There are a number of medications that can be used to treat nausea and vomiting associated with migraines, such as anti-emetics and triptans.
