Why do migraines cause nausea/vomiting?And why does the headache usually go away after throwing up?
In: 13
It is not exactly clear why migraines cause these symptoms, but it is thought that the intense pain of a migraine can trigger a reflex in the brain that causes the muscles in the stomach and intestines to contract, leading to nausea and vomiting.
Some people with migraines may be more sensitive to certain smells, sounds, or lights, which can also contribute to feelings of nausea.
