SICK
S2 E3

What Really Causes a Migraine?

Migraines are more than just headaches. They’re pre-headaches, post-headaches, sensitivities, nausea, fatigue, and can even bring on food cravings. But most of all they are painful and frustrating for those who suffer from them. For years they were misunderstood, but now we know it comes down to two main things, your genes and your brain.

SICK is a new series that looks at how diseases actually work inside our body. We'll be visiting medical centers and talking to top researchers and doctors to uncover the mysteries of viruses, bacteria, fungi and our own immune system. Come back every Tuesday for a new episode and let us know in the comments which diseases you think we should cover next.
