Do Allergies Cause Headaches

An allergic reaction can cause a headache, but not always. In fact, only about 10% of people with allergies actually experience headaches as a result. The other 90% of people with allergies don’t have any headaches at all. Why? It’s because different people experience allergies in different ways. Some people may have mild reactions that cause them to feel a little bit tired and run-down, while others may have severe reactions that make them sick and even cause death. For these people, allergies can definitely cause headaches.
However, for the majority of people who have allergies, their headaches are caused by something else entirely. Almost all the time, headaches are the result of another health problem, like a sinus infection or tension headache. Allergies are only one factor that can contribute to these other problems.
So if you’re having trouble figuring out why you’re getting headaches, be sure to ask your doctor about your allergy status and see if it could be causing any other problems.

How Does An Allergy Cause A Headache?

Allergies are caused by the body’s immune system reacting to something it thinks is harmful. When this reaction occurs in the nose, it’s called sneezing and it’s actually a warning signal that the body is trying to expel an allergen. When an allergen enters the eyes, it can cause a headache because the brain interprets the allergen as a foreign body. In some cases, allergies can also cause a sinus infection or rhinitis, which are both forms of inflammation of the nose and upper respiratory tract.
