Often allergy patients have sleep disordered breathing and want to know if allergies contribute. Most of the time, interruptions in your sleep due to allergy consist of congestion, snoring, sneezing, and possibly apnea. Anything other than those symptoms should be evaluated for alternative causes. Specialists dealing with sleep disorders are allergists, ENT (otolaryngologists) and pulmonologists. There is a board-certification for sleep medicine, so you might want to check for this on listed credentials. Good night!
