Many people with migraine headaches also have stomach issues. These headaches are reported by 88% of Americans.

Some conditions associated with migraines are more likely than others to cause nausea and vomiting. These conditions include:

  • An aura or mild headaches can cause migraine. A person with migraines and aura usually experiences warning signs 20 minutes to an hour before the headache starts, such as nausea, vision problems, and dizziness.
  • Abdominal headache. In some cases, migraines can cause stomach pain in children. These can cause nausea or vomiting.
  • Benign paroxysmal vertigo can also be a sign of migraine in children. However, it is possible for anyone to experience this condition, even if they have never had a migraine.
