Migraine Triggers and Causes Overview
Migraine triggers are factors that contribute to migraine attacks.
Migraine causes are the underlying reasons in the body, especially in the brain, that may chemically lead to migraines.
About migraine triggers
Different migraine sufferers have different migraine triggers, which are also called precipitating factors. The same triggers may not spark a migraine each time. Triggers somehow lead to a series of events in the brain of migraine sufferers which leads to migraine symptoms.
About migraine causes
The underlying reasons for migraines isn’t certain. However, there are several chemical reactions and changes in the brains of people with migraines that have been documented and may cause the recurring attacks.
To better understand your migraines, it is a good idea to write down as much information about your health history. You should also use a migraine journal to keep a record of each and every migraine attack. Write down what you were doing before each attack, anything you ate as well as the weather conditions. This information will help your migraine specialist give you the best advice on avoiding future attacks.
