Rhinitis is a condition that can have the following symptoms: runny nose, sneezing, nasal stuffiness and itching. Rhinitis can result from a variety of causes. These causes include non-allergic or vasomotor rhinitis, rhinitis due to colds or sinus infections, rhinitis due to pregnancy or certain medications, and rhinitis due to alterations in the sinus and nasal anatomy.
Vasomotor rhinitis has symptoms that are very similar to nasal allergies (runny nose, nasal congestion, post nasal drip and sinus pressure) but the cause of the symptoms is different. People with vasomotor rhinitis can have their symptoms triggered by physical factors such as temperature changes, humidity changes, strong odors, air pollution and smoke. Sometimes there is no clear trigger. Vasomotor rhinitis is often referred to as a “migraine of the nose” and in fact there are some people that have associated migraine headaches. While there is no cure for vasomotor rhinitis, there are many medications to help with symptoms include nasal steroid and nasal antihistamine sprays, sinus saline irrigation, and in some cases ipatroprium bromide nasal spray.
Sometimes pregnancy and even medications can cause rhinitis. The most common culprits are over the counter nasal and sometimes oral decongestant therapies. People will often times have overuse of nasal decongestant sprays (a common ingredient in these sprays is called oxymetazoline). Many days of regular use leads to rebound nasal blockage as the medication wears off which then triggers people to use more spray. When people get to this point, they are referred to as being “addicted to their nasal spray.” The following medications have also been associated with rhinitis symptoms: high blood pressure medications (typically in a class called alpha blockers, beta blockers, and calcium channel blockers), some antidepressants, erectile dysfunction drugs, and hormones such as estrogen and progesterone.
The common cold and acute or chronic sinus infections can cause rhinitis symptoms. Sinus infections are discussed separately. Finally, alterations in nasal and sinus anatomy can be associated with rhinitis. In children, enlarged adenoids/tonsils are a common cause of nasal congestion and snoring. Adults can have nasal polyps which are benign growths of inflammatory tissue originating in the sinuses, septal deviations, or more rarely nasal tumors that cause nasal symptoms. Your provider can treat all these conditions.
