Cough-Variant Asthma (Asthma #6)
  • State Key Laboratory of Respiratory Disease, National Clinical Research Center for Respiratory Disease, Guangzhou Institute of Respiratory Health, The First Affiliated Hospital of Guangzhou Medical University, Guangzhou, China

Introduction: Small airway dysfunction commonly presents in patients with classic asthma, which is associated with airway inflammation, disease severity, and asthma control. However, the prevalence of SAD, its relationship with cough severity and airway inflammation, and its development after antiasthmatic treatment in patients with cough variant asthma need to be clarified. This study aimed to investigate the prevalence of SAD and its relationship with clinical and pathophysiological characteristics in patients with CVA and the change in small airway function after antiasthmatic treatment.

Small airway dysfunction occurred in over half of patients with CVA and persisted after short-term antiasthmatic treatment, which showed distinctive clinical and pathophysiological features.

CVA is a milder form of asthma. Children are more likely than adults to have this type of asthma. This condition is often triggered by exposure to specific allergens and environmental factors or activities such as strong odors, pollen, cold air, exercise, and dust.

In fact, patients with CVA are also likely to suffer from other allergic conditions, such as drug and food allergies, eczema, and hay fever.

It causes long and frequent spells of dry and unproductive coughing which can lead to sleep disruption, exhaustion, cracked or fractured ribs, vomiting, and light-headedness.

Moreover, the continued strain on your air tubes can cause them to become narrow and swollen, which disrupts the flow of air to and from the lungs. However, the risk of severe airway narrowing is lower with this type of asthma than with regular chronic asthma.

Cough Variant Asthma Natural Treatment With Homeopathy

As the name suggests, cough variant asthma is a type of asthma that causes a dry, non-productive and constant cough as its primary symptom. It is commonly seen in children, or during early childhood. It may later develop into a typical Asthma condition with wheezing. Once triggered, an episode of cough variant asthma can last for 6-8 weeks. Homeopathic medicine for cough variant asthma can be used with conventional treatment to help reduce the severity of symptoms and treat the chronic condition.

Diagnosing Cough Variant Asthma


You have a persistent cough that does not improve, no matter what you do or the brand cough syrup you take. It seems to linger for weeks after whatever it was that caused it has gone away. Time to go to the doctor to get diagnosed. But how does a doctor determine if you have cough variant asthma as opposed to a stubborn cough?

Unfortunately, many of the tests used for asthma may not work for diagnosing cough variant asthma. Physical exams, chest X-rays, and even spirometry may not reveal cough variant asthma. If thatâs the case, the next step is to take a methacholine challenge test. This test requires the patient to inhale an increasing amount of methacholine aerosol mist before and after a spirometry test. If your lung function drops by 20%, unfortunately, this most likely means asthma or cough variant asthma is present.

After diagnosing the cough variant asthma, you can move onward to treatment.

    S That Can Be Taken To Reduce The Risk Of Developing This Condition

    7 Facts to Know About Cough

    Like chronic asthma, you can avoid CVA by making some lifestyle changes:

    • Avoid exposure to smoke: Both smoking and inhaling second-hand smoke may irritate the airways, thus increasing the frequency and severity of asthma attacks. Therefore, you should avoid areas where people smoke publicly and ask friends and loved ones not to smoke in common areas such as the house and the car.Maternal smoking² also increases the risk of children developing asthma at some point. Therefore, avoid smoking when pregnant as it exposes you and the child to the risk of developing asthma .

    Cough Variant Asthma Triggers

    If you have cough variant asthma, your asthma causes or triggers responsible for your chronic cough are similar to the triggers for other types of asthma. If you have asthma, you will have your own personal list of things that your airways really hate. If you come in contact with or do any of those things on your list, your airways will get really irritated. In the case of cough variant asthma, the result will be your chronic cough.

    The following things are a partial list of possible asthma triggers that might be on your list:

    • Specific foods could pretty much be anything
    • Different types of air pollution
    • Aerosol sprays like hair spray or deodorants, etc.
    • Pet dander all pets give off dander
    • Cockroach droppings
    • Weather could be certain types of weather or changes in the weather

    Gargle With Warm Salt Water

    Salt water is a good home remedy for alleviating irritation in the throat, a common by-product of constant coughing. This beneficial effect rests on the principle of homeostasis and osmosis.

    The saline solution will suck in the moisture from the inflamed throat and, thereby, bring down the swelling. Moreover, gargling with warm salt water has been found to be effective in preventing upper respiratory tract infections, which can often trigger a CVA episode.

    How to do:

  • Add 1 teaspoon of salt to 1 cup of warm water.
  • Stir until the salt completely dissolves.
  • Gargle with this water 2 or 3 times a day.

    A Soothing Honey Drink

    Honey is another very effective natural cure for CVA. The sweetness of honey stimulates your salivary glands to produce more saliva, which in turn lubricates your airways, easing your cough. It also has antioxidant properties that fight inflammation and boost immunity.

    As store-bought honey often comes packed with additional taste-enhancing ingredients such as high fructose corn syrup or sugar, its best to visit a local health store to get premium-quality unadulterated raw honey.

    How to consume:

    • Add 1 tablespoon of raw honey to 1 glass of warm water or milk and drink it slowly. Repeat a few times a day. This drink will have a soothing effect on the throat.
    • Alternatively, mix equal quantities of honey, ginger juice, and pomegranate juice. Consume 1 tablespoon of this mixture 2 or 3 times a day.
    • Before going to bed, consume 1 to 2 teaspoons of raw honey with a little cinnamon powder.
    • Add 1 tablespoon of raw honey to 1 glass of warm tea with lemon and drink slowly.

    Note: Honey is not recommended for children under the age of 12 months as it might contain spores from the bacterium Clostridium botulinum that can cause infant botulism.
