Nasal Allergies: Related Problems

Allergies can cause nasal tissue to swell, making air passages smaller. They also cause mucus production to increase. These result in allergy symptoms. Allergies can cause problems in other part of the body. Some of the more common are listed below. If you have any of these problems, talk to your doctor about treatment options.

Sinuses are spaces in head, some filled with fluid with swollen lining from nasal allergies. Polyps are deep inside nose. Fluid dripping from nose lining down back of throat. Eye is red and swollen.

Sinus Infections

Fluid may be trapped in the sinuses. Bacteria may grow in trapped fluid. This causes sinus infection (sinusitis).

Eye Inflammation

Allergens irritate your eyes. This causes eyes to become red, itchy, puffy, and watery. Eye inflammation is known as conjunctivitis.

Ear Problems

The eustachian tube connects the middle ear to nasal passages. Air passes in and out of the ear through this tube. Allergies can block this tube. Trapped air can make the ear feel plugged. Fluid may also build up, leading to an ear infection (otitis media).

Nasal Polyps

Allergies cause nasal tissues to swell. Constant swelling can lead to formation of a sac called a polyp. Polyps can grow large enough to block nasal passages.


Asthma is inflammation and swelling of the air passages in the lungs. It can make breathing harder. Asthma is often related to allergies.
