Rhinitis is a condition that involves a constant runny nose, sneezing, and nasal stuffiness. When these symptoms are not caused by hay fever or allergies, the condition is called non-allergic rhinitis. One type of non-allergic rhinitis is called vasomotor rhinitis.
Rhinitis - nonallergic; Idiopathic rhinitis; Nonallergic rhinitis
Causes, incidence, and risk factors
Vasomotor rhinitis is not caused by an infection or allergy. The exact cause is unknown. Symptoms are triggered by something that irritates the nose, such as:
- A dry atmosphere
- Air pollution
- Certain medications
- Spicy foods
- Strong emotions
- Runny nose
- Nasal congestion (stuffy nose)
- Watery nasal drainage (rhinorrhea
Signs and tests
The doctor will ask about your symptoms, when they occur, and what seems to trigger them.
You will also be asked about your home and work environment. The doctor may look inside your nose and see that the tissues lining the nose are swollen due to inflamed blood vessels.
An allergy skin test
may be done to rule out allergies as a cause of your symptoms.
If your doctor determines you cannot have skin testing, special blood tests may help with the diagnosis. These tests, known as IgE RAST tests, can measure the levels of allergy-related substances..A complete blood count (CBC) test, called the eosinophil count
, may also help diagnose allergies.
The main treatment is simply avoiding the things that trigger your symptoms.
In some cases, decongestants or a nasal spray containing an antihistamine may help. Corticosteroid nasal sprays may be useful for some forms of vasomotor rhinitis.
