Caffeine can be both a treatment and a trigger for migraines. Knowing if you benefit from it may be helpful in treating the condition. Knowing if you should avoid or limit it can also help.
Read on to learn more about the connection between caffeine and migraines.
Migraines can be caused by a variety of triggers. These include everything from:

A variety of medicines used to treat migraines contain caffeine. So you may be consuming it even if you aren’t a regular coffee or tea drinker.
