One in three sufferers suspects that alcohol is occasionally responsible for migraine attacks. One in ten considers alcohol to be a sure cause of their migraines.
Substances found in alcoholic drinks can cause migraine attacks, such as tyramine which occurs naturally as a result of fermentation processes in food. Alcohol has a euphoric effect. Tyramine can increase performance and motivation. Various messenger substances in the body are the cause of this, such as dopamine and noradrenaline. These substances cause the body to use up energy reserves faster and increase the sufferers susceptibility to migraine attacks. The time of day at which alcohol is consumed can also have an effect on your susceptibility. A glass of champagne at a birthday party at the office can perhaps contribute to a migraine later on in the day, while a glass of red wine before going to bed has no consequences.
