Ear, Nose, and Throat Allergies


With millions of people suffering from allergies, allergy symptoms appear when the immune system reacts to an allergic substance that has entered the body as though it was an unwelcome invader. The immune system will produce specific antibodies that are capable of recognizing the same allergic substance if it enters the body at a later time.

Many patients do not know they have allergies. The symptoms may mimic a cold and flu, or only appear hours or days after being exposed to the allergen.


One of the most common medical problems in children in early childhood. Allergic inflammation can cause swelling in the nose and around the opening of the ear canal. The swelling has potential to interfere with drainage of the middle ear. When bacteria laden discharge clogs the tube, infection is more likely.


Allergies can cause enough inflammation that the opening to the sinuses is obstructed. A bacterial sinus infection occurs as a result. Allergens that are breathed in can often cause a stuffy nose, itchy nose and throat, mucus production, cough, or wheezing.


Various allergens may also lead to the formation of too much mucus which can make the nose run or drip down the back of the throat, leading to “post-nasal drip”. It can lead to coughing, sore throats, and a husky voice. It is more common in older people and in dry inland climates, thick, dry mucus can also irritate the throat and be hard to clear.
