About Vasomotor Rhinitis (Nonallergic Rhinitis)

Overview
Vasomotor rhinitis is a condition characterized by inflammation of the membranes inside the nose. It is the most common form of nonallergic rhinitis, which means that it is not caused by allergies. Vasomotor rhinitis is not life-threatening, but it can cause uncomfortable symptoms such as nasal congestion, sneezing, and runny nose. The exact cause of vasomotor rhinitis is not known, but it is believed to involve the dilation (expansion) of blood vessels inside the nose, leading to swelling and congestion. Various triggers can contribute to this condition, including environmental irritants like perfumes or second-hand smoke, changes in weather, viral infections, certain medications, hormonal changes, stress, and more. The first-line treatment for vasomotor rhinitis includes antihistamines, decongestants, and corticosteroids. In some cases where symptoms persist, surgery may be considered to reduce the volume of nasal tissue.
Causes and Risk Factors

The exact cause of vasomotor rhinitis is not known, but there are certain triggers that can lead to the symptoms. Some common causes and triggers of vasomotor rhinitis include:

  • Irritants in the environment such as perfumes, odors, smog, or second-hand smoke
  • Changes in the weather, particularly dry weather
  • Viral infections such as those associated with a cold or flu
  • Hot or spicy foods or drinks
  • Medications such as aspirin, ibuprofen, beta-blockers, certain sedatives, antidepressants, oral contraceptives, and drugs used to treat erectile dysfunction
  • Overuse of nasal decongestant sprays
  • Hormonal changes associated with pregnancy or menstruation
  • Hypothyroidism
  • Stress

These triggers can cause the blood vessels inside the nose to dilate or expand, leading to swelling and congestion. Mucus may also drain from the nose.

Risk factors for vasomotor rhinitis can be categorized into non-modifiable and modifiable factors. Non-modifiable risk factors are factors that cannot be changed, while modifiable risk factors can possibly be changed by a person’s actions.

Non-modifiable risk factors for vasomotor rhinitis include:

  • Age: Increasing age is a non-modifiable risk factor for this condition.
  • Genetic predispositions: Positive family history of vasomotor rhinitis may increase the risk of developing the condition.
  • Previous history of polyps: Individuals with a history of nasal polyps may have a higher risk of developing vasomotor rhinitis.

Some examples of modifiable risk factors include:

  • Exposure to irritants or vasomotor rhinitis triggers, like cigarette smoke and chemical fumes.
  • Poor dietary habits: Maintaining a healthy diet can help reduce the risk of developing vasomotor rhinitis.
  • Low physical activity: Being physically active is important in reducing the risk of this condition.
Symptoms

Vasomotor rhinitis symptoms can vary depending on the severity of the condition. Here are some common symptoms:

  • Stuffy nose: This is a feeling of congestion or blockage in the nose.
  • Runny nose: You may experience a watery discharge from your nose.
  • Mucus in the throat or postnasal drip: This is when mucus drips down the back of your throat.

Other symptoms with more severe vasomotor rhinitis include:

  • Nasal obstruction: This is when your nasal passages become blocked, making it difficult to breathe through your nose.
  • Sinus headaches: You may experience pain or pressure in your sinuses, which are located around your nose and eyes.
  • Post-nasal drip: This is when excess mucus drips down the back of your throat, causing a sensation of mucus in the throat.
  • Worsening nasal congestion: Your nasal congestion may become more severe over time.
  • Rhinorrhea: This refers to a persistent runny nose.
  • Sneezing: You may experience frequent sneezing.
  • Itching: Itching may occur in the nose, throat, or ears.

It's important to note that vasomotor rhinitis does not typically cause itchy nose, itchy or watery eyes, or a scratchy throat, which are common symptoms of allergic rhinitis caused by allergies.

Diagnosis

To diagnose vasomotor rhinitis, doctors may perform the following examinations, tests, and procedures:

  • Medical history and physical exam: The doctor will ask about your symptoms, when they started, and triggers that may have started the symptoms. They may ask about your medical history, current medications, and exposure to smoke or other fumes. They will check your nose and sinuses as part of the physical examination.
  • Allergy testing: Since vasomotor rhinitis has similar symptoms to allergic rhinitis, doctors may need to rule out allergies as a possible cause. They can do this through allergy testing, which can be done in two ways:
    • Skin trick test: This test involves placing small amounts of allergens on your skin and pricking or scratching the surface to see if you have an allergic reaction.
    • Patch test: This test involves applying small amounts of potential allergens to adhesive patches, which are then placed on your skin for a period of time to check for a delayed allergic reaction.
  • Blood test: A blood test may be done to measure antibody levels in your bloodstream. This test can help determine if your immune system is functioning normally.
  • Nasal endoscopy: In some cases, doctors may use a nasal endoscope to look inside your nose. This procedure involves inserting a thin, flexible tube with a light and camera into your nasal passages to examine the nasal tissues and identify any abnormalities.
  • CT scan: A CT scan of the sinuses may be ordered by your doctor to check for any sinus problems that could be causing your rhinitis. This imaging test provides detailed images of the nasal cavities and sinuses, helping to rule out other potential causes.

Additional examinations and assessments that can help determine the severity of vasomotor rhinitis include:

  • Visual analogue scale (VAS): Doctors use a VAS to assess the severity of ocular (eye-related) and nasal symptoms associated with vasomotor rhinitis. You may be asked to rate symptoms on a scale from 0-10 to help the doctor determine if symptoms are mild, moderate, or severe.
  • Activity impairment assessment: The severity of rhinitis can also be evaluated based on how it impairs daily activities such as sleep, work/school performance, and troublesome behavior.

It's important to note that these examinations, tests, and procedures are performed by medical professionals to accurately diagnose vasomotor rhinitis and determine its severity. If you suspect you have vasomotor rhinitis or any other health concerns, it's best to consult with a healthcare provider for proper evaluation and guidance.

Treatment Options

The goals of treatment for vasomotor rhinitis are to minimize symptoms and improve the patient's quality of life. The treatment options include:

  • Avoidance of trigger factors: The first-line treatment involves avoiding substances that trigger symptoms. This can include avoiding exposure to irritants like tobacco smoke, chemical fumes, strong odors, or dust.
  • Exposure reduction: In some cases, it may be difficult to completely avoid triggering substances. In these situations, reducing exposure can be helpful. This can involve wearing protective equipment at the workplace, reducing exposure time, or changing materials or work steps.
  • Medications can be used to help control symptoms of vasomotor rhinitis. Some common medication treatment options include:
    • Over-the-counter (OTC) saline nasal sprays: These help reduce swelling and relieve a blocked nose by moisturizing the nasal passages.
    • OTC decongestants: Examples include pseudoephedrine or phenylephrine. They work by narrowing blood vessels in the nasal passages, reducing congestion. If you have high blood pressure (hypertension) do not start these medications without consulting with your healthcare provider.
    • OTC corticosteroid nasal sprays: These reduce inflammation in the nasal passages, relieving symptoms. An example is fluticasone nasal spray.
    • Prescription corticosteroid nasal sprays: These are stronger versions of OTC corticosteroid sprays and may be prescribed if symptoms are severe or not controlled with OTC options. An example is mometasone nasal spray.
    • Antihistamine nasal sprays: These help reduce inflammation and relieve congestion. Examples include azelastine or olopatadine hydrochloride.
    • Anticholinergic nasal sprays: These widen the airways, ease breathing, and reduce mucus production. Examples include ipratropium nasal spray.
    • Sodium cromoglicate nasal spray: This reduces inflammation and mucus production.

It's important to note that oral antihistamines are not very effective in treating vasomotor rhinitis.

  • In some cases, if there are underlying health conditions that worsen symptoms (such as nasal polyps or a deviated septum), surgery may be recommended as a treatment option.

It's important to remember that the specific treatment plan will depend on the individual's symptoms and needs. Consulting with a healthcare professional is recommended for personalized advice and guidance on managing vasomotor rhinitis effectively.

Progression or Complications

The natural progression of vasomotor rhinitis can vary depending on the individual and the severity of their symptoms. In some cases, symptoms may remain stable or even improve over time. However, for others, symptoms may worsen or persist. It's important to note that vasomotor rhinitis is a chronic condition and may require ongoing management.

When it comes to complications of vasomotor rhinitis, they are generally less common compared to other types of rhinitis such as allergic rhinitis. However, vasomotor rhinitis can still have an impact on a person's quality of life. Common complications that can occur include:

  • Chronic nasal congestion: This can lead to difficulty breathing through the nose and may affect sleep quality.
  • Sinus infections: The persistent nasal congestion can create an environment where bacteria can thrive, increasing the risk of sinus infections.
  • Eustachian tube dysfunction: The Eustachian tubes connect the middle ear to the back of the throat. When these tubes become blocked or dysfunctional due to nasal congestion, it can lead to ear problems such as ear pain or pressure.
  • Sleep disturbances: Nasal congestion and difficulty breathing through the nose can disrupt sleep patterns and lead to daytime fatigue.

It's important to remember that while treatment can help alleviate symptoms and improve quality of life for individuals with vasomotor rhinitis, there is currently no cure for this condition. The goal of treatment is typically focused on symptom management rather than complete resolution.

If you have concerns about vasomotor rhinitis or its impact on your health, it's always best to consult with a healthcare professional who can provide personalized advice and guidance based on your specific situation.
