Allergies and migraine headaches

Can Allergies Cause Headaches or Migraines?

Allergies might be the reason for your migraine.

Allergy season got you down? Approximately one in five people in the United States experience symptoms of seasonal allergies or hay fever (also known as allergic rhinitis).1 Such allergies can sometimes be accompanied by headaches and migraines. In fact, people who have seasonal allergies are more likely to also experience migraine headaches, and many suffer from both conditions at the same time.1,2 Additionally, studies have demonstrated that seasonal allergy sufferers are reported to be 4 to 14 times more likely to experience migraine headaches than those without allergies.3,4,5,6

Both seasonal allergies and migraines might be connected to similar environmental factors such as weather changes or other seasonal migraine triggers.2 For example, some individuals may be particularly sensitive to ragweed pollen and other fall migraine triggers, while others may be more affected during the spring and summer months, when even the perfume of flowers or other intense smells may trigger migraine headaches.2

Migraines and seasonal allergies can affect the same parts of the body such as the forehead, the nose and the areas between, behind and around the eyes.2

Seasonal allergy symptoms, particularly those that may be similar to those of a migraine headache, are important symptoms that you should discuss with your doctor. Links between your allergies and your migraines may help you and your physician better understand your attacks.

One way to help determine if seasonal allergy symptoms actually suggest a migraine headache, or may trigger your headaches, is to keep a migraine diary and share it with your doctor.
