In some people, the cause of migraine can be identified. However, identifying factors resulting to this headache in some is not possible. Basically, migraine can be attributed to the enlargement of blood vessel and the release of nerve fiber chemicals from the nerves coiling around blood vessels. One or more arteries may enlarge while an individual is suffering from this headache. This artery is usually located outside the skull beneath the skin. This results to chemical release which eventually causes inflammation and pain. It also accelerates more artery enlargement. This process can be triggered by a number of factors.
- Allergies or allergic reactions,
- Loud noise, bright lights, perfumes or some odors,
- Emotional or physical stress,
- Smoke exposure or smoking,
- Exposure to very high or low temperatures can also cause migraine.
- There are also cases of migraine that can be associated with a family where one comes from. Some people who suffer from migraines hail from families where their parents or members of their families suffer the same condition.
- Exposure to an environment different from the one an individual is used to can also cause migraine. Medical practitioners say that such headache is as a result of the body trying to adapt to the different environment.
- Irregular sleep or a change in the sleeping pattern that one is used to.
- Fasting or skipping meals,
- Tension headache,
- Pills taken for birth control, fluctuation of the menstrual cycle and even hormonal changes at the onset of menopause,
- Consumption of foods with tyramine. These include aged cheese, red wine, chicken livers, smoked fish, some beans and figs.
- Nitrates such as hot dogs, bacon and salami can also cause migraine,
- Monosodium glutamate can also cause migraine.
- Products such as nuts, chocolate, avocado, citrus, peanut butter, dairy products and banana can cause migraine in some people. Even pickled or fermented foods can cause migraine in some individuals.
Although one may be able to identify triggers of migraine, it does not always imply that avoiding them will lead to complete prevention of migraine from occurring.
