MIGRAINES
The classic feature of migraines is a throbbing
headache, usually on one side of the head only. This is caused by
the narrowing and dilating of the blood vessels in a part of one
side of the brain. Migraine headaches may be triggered by different factors
including stress, hormonal changes, oral contraceptives, allergies,
changes in barometric pressure, and certain foods. Migraines affect
about 10% of the population and can occur anywhere from once a week
to once or twice per year. Women typically get migraines around
menstruation, when estrogen levels are low.
Studies have shown that raising serotonin levels can
greatly help those with migraines. Levels of serotonin drop during a
headache.
