Migraines are common, affecting aboutone infour women andone in twelve men in the UK. It is thought that hormonal influences may be the reason why migraines affect more women than men. For example, some women find that migraine attacks are more common around the time of their period. However, this association has not been fully proven.
Migraine headaches seem to be caused in part by changes in the level of a body chemical called serotonin. Serotonin plays many roles in the body, and it can have an effect on the blood vessels. When serotonin levels are high, blood vessels constrict .When serotonin levels fall, the blood vessels dilate. This swelling can cause pain or other problems. Many things can affect the level of serotonin in your body, including your level of blood sugar, certain foods and changes in your estrogen level if you are a woman.
You may also have a “premonition” several hours to a day before your headache starts. Premonitions are feelings you get that can signal a migraine is coming. These feelings can include intense energy, fatigue, food cravings and mood changes.
