What is migraine?
Migraine is a particular kind of headache that is episodic (generally occurs from one to four times a month), is throbbing in nature and generally on side of the head. Sometimes pain may be on both sides of head.
What is the cause of migraine?
Migraine occurs due to spasm of the blood vessels supplying the brain. This leads to expansion of other blood vessels and throbbing of vessels to maintain blood and oxygen supply to the brain. This leads to a pounding and throbbing headache.
Usually migraine occurs due to certain triggering factors. Common triggers are:
- Exposure to bright light
- Exposure to certain food (chocolates, cheese, bananas, yogurt, fried food, monosodium glutamate).
- Too much caffeine
- Sleep problems
Though, why a particular person gets migraine is still not known, it is usually found to run in families and may have a genetic basis.
