Nausea and vomiting may occur with many types of headaches,
especially
migraine headaches, and may continue for 8 to 24
hours. Nausea and vomiting with a headache that doesn't get better or go away
may be a sign of another serious medical problem or serious illness, such
as:
- Inflammation of the brain (encephalitis).
- Infection of the fluid and
tissues that surround the brain and spinal cord (meningitis).
- A pocket of infection in the
brain (brain abscess).
- Bleeding within or around
the brain.
If ongoing nausea and vomiting occur with a headache,
dehydration may become a problem. Dehydration can
occur very quickly in young children and older adults. When you have a headache
and prolonged nausea and vomiting, watch for signs of dehydration.
