Why do migraines make you vomit?

Migraines are a type of headache that comes in the form of attacks lasting from half a day to several days. But most often a migraine attack lasts for a whole day. The main symptom of migraine is a strong and intense headache, especially when you exert yourself and move your head. Next, other symptoms of migraine include nausea, sensitivity to light, fatigue and difficulty concentrating.

Why do people vomit in migraine and not in other headaches?

The reason why people sometimes vomit in migraine is neurological. Migraines affect the blood vessels of the head and when a migraine attack increases the activity of the trigeminal nerve, you feel sick and vomit. That’s because the trigeminal nerve is a part of the brain that regulates nausea and vomiting.

Many people with migraines report feeling sensations before a migraine attack.

These sensations can be:

  • Yawns
  • Unusual redness
  • Mood swings
  • Discomfort in the body
  • Stomach problems
  • Swollen feet and hands.

Finally, migraine is partly hereditary and people with the condition usually have about one attack per month.
