Asthma and COVID-19: Risks, Symptoms and Management

Introduction

If you suffer from asthma, you have probably become more aware of your health since the emergence of COVID-19. Let's walk through those concerns together. This article discusses the connection between asthma and COVID-19, ranging from risks and symptoms to proper management.

Does Asthma Increase the Risk of Severe COVID-19?

What Do the Studies Say Regarding COVID-19 Severity and Asthma?

Early on, medical professionals worried that asthma could substantially raise the risk of severe COVID-19. However, recent studies indicate the connection is more complex. While a respiratory condition can complicate any viral infection, research has indicated that asthma by itself could not be as large a risk factor as initially anticipated.

The good news is that asthma does not seem to increase your risk of serious COVID-19 outcomes, like hospitalization, if it is properly managed. However, uncontrolled asthma with recurring symptoms might be associated with worse COVID-19 outcomes.

Asthma vs. COPD: Differences in COVID-19 Risk

When it comes to COVID-19 risk, it is essential to differentiate between asthma and chronic obstructive pulmonary disease (COPD). Although both are pulmonary conditions, COPD has been more reliably associated with severe outcomes of COVID-19 compared to asthma.

Individuals with COPD generally have more permanent lung damage and are more susceptible to respiratory infections. Asthma, on the other hand, includes inflammation and constriction of airways that may be easily controlled with the right medication.

Does COVID-19 Cause Asthma Attacks?

As with other respiratory viruses, certainly, if you already have asthma, COVID-19 may exacerbate your symptoms or potentially cause an asthma attack. It is like stoking the flames. The virus inflames the airways, possibly leading to:

• More wheezing.

• Tightness in the chest.

• Coughing.

• Shortness of breath.

If you have asthma and become infected with COVID-19, it is essential to keep taking your asthma medicines as directed and pay close attention to your symptoms.

Can COVID-19 Trigger New or Exacerbating Asthma?

One of the new phenomena being researched by scientists is what has been referred to as "COVID-induced asthma"—asthma symptoms that occur following a COVID-19 infection in individuals who did not have asthma before.

Although still being researched, mounting evidence suggests that COVID-19 can also cause new-onset asthma or asthmatic symptoms in certain people. The virus can induce airway inflammation that could continue even after the acute infection has cleared.

Not all people who contract COVID-19 will become asthmatic later, but some who have a history of asthma or allergies in the family could be at risk.

Consult a Doctor if You Have:

• Wheezing or coughing that persists for longer than two to three weeks since recovering from COVID-19.

• Shortness of breath when carrying out light work or at rest.

• Chest tightness that does not get better.

• Coughing or breathing problems at night that wake you up.

• Symptoms affecting daily life.

These may signal COVID-induced asthma that needs to be diagnosed and managed.

What Causes Wheezing and Asthma Symptoms Following COVID-19?

Wheezing after COVID-19 is surprisingly prevalent, even among individuals who have no prior respiratory conditions. This is because the virus can harm the lining of the airways, and subsequent inflammation and narrowing take place in a fashion similar to asthma.

The virus can also amplify airway hyperresponsiveness, in which the airways are more responsive to irritants and tend to constrict. This can lead to a wheezing sound when inhaling.

The Causes of Asthma in People After COVID-19

There are several reasons why individuals get asthma after COVID-19:

• The virus causes direct damage to airway cells.

• COVID-19 provokes an overactive immune response that results in chronic inflammation.

• Existing airway sensitivity that had not been previously diagnosed.

• Genetic susceptibility to developing asthma that was "triggered" by the viral infection.

Long COVID-19 and Respiratory Complications

Long COVID is used to describe persistent symptoms that last for weeks or months following the initial resolution of infection. Up to 25 percent of those with long COVID-19 are said to suffer from ongoing breathing problems, such as:

• Wheezing.

• Chronic cough.

• Shortness of breath.

• Decreased exercise tolerance.

These signs can be similar to asthma and might need to be treated in the same way.

How to Treat Post-COVID-19 Asthma Symptoms?

If you are having asthma-type symptoms following COVID-19:

1. Monitor your symptoms and possible triggers.

2. Monitor your lung function with a peak flow meter.

3. Obey your physician's instructions for rescue inhalers or other medicines.

4. Steer clear of recognized respiratory irritants such as smoke, pungent odors, and air pollution.

5. Stay well-hydrated and keep healthy humidity in your dwelling.

How to Control Asthma During COVID-19?

You’re not alone in this. If you have asthma and have developed COVID-19, you can do the following to prevent the flare-ups:

• Keep taking all your prescribed asthma medications on schedule.

• Keep a stash of rescue medication within easy reach.

• Check your peak flow readings more often.

• Use your asthma action plan and identify when you need emergency treatment.

• Stay well-hydrated and rest plenty.

• Avoid other respiratory irritants.

Safe Inhaler and Nebulizer Use During Infection

Inhalers and nebulizers are still valuable instruments for controlling asthma in COVID-19 infection. Nevertheless, if you are on a nebulizer while infected:

• Use it in a well-ventilated area away from other members of the household.

• Thoroughly clean and disinfect the equipment after every use.

• Try temporarily using metered-dose inhalers with spacers if your doctor recommends them.

When to Change Medicines When Ill

Some individuals will require medication modifications during COVID-19 illness. Always check with your healthcare provider first, but know that:

• Your physician may temporarily raise the dose of controller medications.

• More frequent use of the rescue inhaler might be needed.

• On some occasions, an oral steroid may be prescribed for a short period.

Is It Safe to Use Steroid Inhalers During COVID-19?

While you might be worried, doctors assure you that inhaled steroids are safe when it comes to controlling asthma during a COVID-19 illness because they target the lungs and not the immune system.

What Do Experts Say About Corticosteroids and Immunity?

Contrary to initial fears, medical professionals today largely concur that inhaled corticosteroids for the control of asthma are safe during COVID-19. Indeed, some research indicates they may even offer some immunity against severe COVID-19.

The advantages of good asthma control with inhaled steroids as prescribed far exceed any theoretical hazard. These drugs act mostly in the airways and not on the whole immune system.

Why It’s Risky to Stop Asthma Medications?

Stopping asthma medications, particularly during a respiratory illness, can result in:

• Asthma attacks that can need emergency treatment.

• Worsening inflammation that makes it harder to breathe.

• Increased risk of severe COVID-19 complications.

• Possibly longer recovery time.

Always talk with your healthcare provider before making any medication changes.

How Can You Prevent COVID-19 Complications if You Have Asthma?

1. Vaccination Guidelines for Patients With Asthma

COVID-19 vaccination is recommended for those with asthma. The vaccines were found to be safe and effective among individuals with asthma, and the protection they afford is particularly useful in light of the respiratory complications of COVID-19.

Those with asthma are advised to:

• Be up to date with advised COVID-19 vaccines and booster doses.

• Address any concerns with vaccination with their health care provider.

• Resume all asthma medicines before and after vaccination.

2. Preventing Respiratory Infections and Asthma Triggers

Aside from vaccination, these prevention steps are still significant:

• Frequent and thorough hand washing.

• Use well-fitting masks in high-risk environments if COVID-19 is prevalent.

• Practice physical distancing when needed.

• Stay away from known asthma triggers such as smoke, pungent odors, and allergens.

• Clean indoor air using HEPA (high-efficiency particulate air) filters if available.

• Stay home if ill to prevent infecting others.

What Are the Best Tips for Strengthening Lung Health After COVID?

1. Asthma Recovery Breathing Exercises

Certain breathing exercises can increase respiratory muscle strength and lung capacity after COVID-19:

• Diaphragmatic (Belly) Breathing: Pay attention to the deep breathing that makes your abdomen, not chest, rise

• Pursed-Lip Breathing: Breathe in through your nose, followed by slow exhalation through pursed lips

• Incentive Spirometry: If your physician advises, this device can inflate your lungs

• Yoga Breathing Exercises: Techniques such as pranayama can enhance respiratory effectiveness

Begin slowly and gradually lengthen the duration as your strength increases.

2. Lifestyle Modification to Enhance Respiratory Function

Some lifestyle changes can facilitate lung healing:

• Maintain optimal weight to minimize respiratory strain.

• Perform moderate, regular exercise as tolerated.

• Follow an anti-inflammatory diet of fruits, vegetables, and omega-3 fatty acids.

• Hydrate adequately to maintain thin airway secretions.

• Eliminate smoking and exposure to secondhand smoke.

• Use mindfulness, meditation, or other methods to control stress.

How Does COVID-19 Affect Children With Asthma and What Should Parents Know?

The better news is that much research suggests that children with asthma do not seem to have considerably greater risks from COVID-19 than children who do not have asthma. Even more reassuringly, children tend to have had less severe symptoms of COVID-19 than adults during the pandemic.

However, good control of asthma in children is still necessary during any respiratory infection, such as COVID-19.

Prevention for Children With Asthma

Parents of children with asthma must:

• Ensure children remain on controller medication as directed.

• Have rescue medications at home.

• Instruct in proper hand washing and respiratory hygiene.

• Vaccinate as recommended based on current age guidelines.

• Have regular asthma check-ups in person or by telehealth.

• Modify asthma action plans with health providers.

Post-COVID-19 Asthma Symptoms Management in Children

If your child experiences new or worsening asthma symptoms following COVID-19:

• Record symptoms such as timing, severity, and possible triggers.

• Discuss with your pediatrician or asthma expert.

• Adhere to suggested medication changes.

• Track exercise tolerance and activity level.

• Be aware that recovery can take time, particularly for older children and adolescents.

Conclusion

Asthma and COVID-19 may affect one another. If you become infected with COVID-19, it can make breathing harder or even cause asthma-type issues. Fortunately, well-managed asthma doesn't appear to significantly worsen COVID-19 in most individuals. Keep on taking your asthma medications even when you have COVID-19. If you begin wheezing or have breathing difficulties after having COVID-19, inform a doctor immediately. They can make you breathe easier. With proper care and by doing what your doctor tells you, you can remain healthy even if you have asthma in these COVID-19 times.
