Can Post Nasal Drip Cause Wheezing and Shortness of Breath?

Introduction: Can Post Nasal Drip Cause Wheezing and Shortness of Breath?

Post nasal drip is a common condition characterized by the excessive production of mucus in the nasal passages and throat. While it is typically associated with discomfort and a persistent need to clear the throat, some individuals may also experience secondary symptoms such as wheezing and shortness of breath. In this blog post, we will explore the potential link between post nasal drip and respiratory symptoms, delving into the underlying mechanisms and offering insights into management strategies.

Understanding Post Nasal Drip:

Post nasal drip occurs when excess mucus accumulates in the back of the throat instead of being expelled through the nose. This can be due to various factors, including allergies, sinus infections, colds, flu, and certain medications. Symptoms of post nasal drip often include a sensation of mucus dripping in the throat, frequent throat clearing, tickling or scratchy throat, and the urge to cough.

The Relationship between Post Nasal Drip, Wheezing, and Shortness of Breath:

  1. Irritation of the Airways: The excess mucus associated with post nasal drip can irritate the airways, leading to inflammation. This inflammation can trigger a cascade of events in the respiratory system, potentially causing wheezing and shortness of breath.
  2. Allergic Reactions: Post nasal drip can be triggered by allergies, such as allergic rhinitis. When allergens come into contact with the nasal passages, they can stimulate the production of excess mucus, leading to post nasal drip. In individuals with allergic asthma, this allergic response can extend to the lower airways, resulting in wheezing and shortness of breath.
  3. Asthma and Post Nasal Drip Connection: Asthma and post nasal drip frequently coexist. The presence of post nasal drip can exacerbate asthma symptoms, leading to wheezing and breathlessness. The excess mucus produced in post nasal drip can trigger or worsen asthma attacks, making it vital to manage both conditions concurrently.

Managing Post Nasal Drip and Related Respiratory Symptoms:

  1. Nasal Irrigation: Nasal irrigation with a saline solution can help flush out excess mucus and allergens from the nasal passages, reducing post nasal drip and associated respiratory symptoms. Neti pots or squeeze bottles can be used to perform nasal irrigation safely.
  2. Steam Inhalation: Inhaling steam from a hot shower or using a facial steamer can help loosen mucus in the airways, alleviating post nasal drip and associated breathing difficulties.
  3. Allergy Management: If post nasal drip is caused by allergies, identifying and avoiding allergens to the best of your ability can minimize symptoms. Over-the-counter antihistamines and nasal corticosteroids may also provide relief.
  4. Hydration: Staying adequately hydrated can help thin out mucus, making it easier to clear the respiratory passages. Drinking plenty of water and warm liquids throughout the day is essential in managing post nasal drip.
  5. Elevating the Head: Sleeping with your head slightly elevated using an extra pillow or an adjustable bed can help reduce mucus accumulation in the throat, preventing it from triggering wheezing and shortness of breath during sleep.
  6. Medical Intervention: In severe cases or when symptoms persist despite self-care measures, it may be necessary to consult a healthcare professional. They can assess your condition, conduct tests if needed, and prescribe appropriate medication or therapies to alleviate symptoms and manage post nasal drip effectively.


Post nasal drip, characterized by the excessive production of mucus in the nasal passages and throat, can potentially lead to respiratory symptoms such as wheezing and shortness of breath. The mechanisms behind this connection involve irritation of the airways, allergic reactions, and the coexistence of post nasal drip and asthma. Understanding the relationship between post nasal drip and respiratory symptoms allows for targeted management strategies, including nasal irrigation, steam inhalation, allergy management, hydration, and head elevation. If symptoms persist or worsen, consult a healthcare professional, who can provide further guidance and intervention. By addressing post nasal drip and its associated respiratory symptoms, individuals can experience improved quality of life and respiratory well-being.
