Asthmatic Bronchitis: Symptoms, Causes & Treatment

Asthmatic bronchitis refers to inflammation of the bronchial tubes, which carry air in and out of the lungs. This condition can lead to symptoms such as difficulty breathing, a persistent cough, and wheezing.

Although the term “asthmatic bronchitis” is commonly used, it is not a formal medical diagnosis. Healthcare professionals typically classify it as asthma, which may be triggered by allergies, respiratory infections, or certain medications like nonsteroidal anti-inflammatory drugs (NSAIDs).

Management of asthmatic bronchitis is guided by a pulmonologist and focuses on controlling inflammation and preventing symptoms. Treatment usually includes inhalers, nebulizer therapy, and environmental measures such as reducing exposure to allergens.

Main symptoms

The most common symptoms of asthmatic bronchitis include:

• Shortness of breath

• Persistent cough, which may be dry or produce mucus and often worsens at night

• A feeling of tightness or pressure in the chest

• Difficulty breathing

• Wheezing

During flare-ups, additional symptoms may include rapid, shallow breathing, prolonged exhalation, a fast heart rate, dizziness, or confusion.

Symptoms may last for a few hours or days but usually improve once exposure to the allergen is reduced or when prescribed medication is taken.

Confirming a diagnosis

A pulmonologist diagnoses asthmatic bronchitis by reviewing symptoms, medical history, and any history of allergies, along with a physical exam that includes listening to the lungs.

Additional tests may be ordered, such as spirometry, bronchoprovocation testing, chest X-ray, or allergy testing.

Possible causes

Common causes of asthmatic bronchitis include:

• Allergies to dust mites, mold, pollen, plants, animal dander, or cockroaches

• Exposure to cold air

• Respiratory infections, such as the flu or the common cold

• Allergic rhinitis or chronic sinusitis

• Smoking or exposure to environments with high levels of smoke or dust

• Intense physical activity

• Use of nonsteroidal anti-inflammatory drugs (NSAIDs)

Other potential triggers include stress or strong emotions, gastroesophageal reflux disease (GERD), and food allergies.

Asthmatic bronchitis is more likely to occur in children, adolescents, and young adults, especially those born prematurely or with a family history of asthma.

Treatment options

Treatment for asthmatic bronchitis should be guided by a pulmonologist and aims to reduce airway inflammation and prevent symptoms.

The main treatment approaches include:

1. Reducing allergens at home

Keeping the home environment clean is essential to prevent allergy-triggered flare-ups and help relieve symptoms.

It is recommended to reduce dust and mold by cleaning regularly with a damp cloth and using products without strong odors.

Washing bedding weekly and minimizing items like stuffed animals, curtains, and rugs can also help reduce allergen exposure.

2. Medications

Medications are prescribed to reduce inflammation in the bronchial tubes and improve airflow.

The most commonly used medications include:

• Asthma inhalers, such as budesonide, fluticasone, mometasone, or albuterol

• Nebulizer solutions, such as albuterol or ipratropium bromide

• Oral corticosteroids, such as prednisone or prednisolone

• Leukotriene modifiers, such as montelukast

• Monoclonal antibodies, such as omalizumab

These medications should only be prescribed by a healthcare provider, since some are intended for long-term management while others are meant to relieve symptoms quickly.

Antibiotics may also be prescribed if a bacterial infection is present.

3. Hospitalization

Hospitalization may be required during severe flare-ups and can include nebulizer treatments, oral corticosteroids, and intravenous (IV) magnesium sulfate.

In more severe cases, intubation or mechanical ventilation may be necessary.

4. Respiratory therapy

Respiratory therapy may be recommended to improve breathing capacity and overall physical conditioning.

This therapy is guided by a respiratory or physical therapist and includes exercises that strengthen breathing muscles, expand lung capacity, and help clear mucus from the airways.

5. Physical exercise

Regular physical activity may be recommended to improve cardiovascular and respiratory fitness, supporting better symptom control.

Swimming is often a good exercise because it helps strengthen the respiratory muscles, but it should only be started after a medical evaluation and under professional guidance.

Is there a cure?

Asthmatic bronchitis may be resolved if the underlying trigger, such as an allergy or infection, can be eliminated.

In some cases, this may be achieved with specific immunotherapy or vaccines recommended by a specialist. However, asthma itself does not have a cure, and many underlying allergies cannot be fully eliminated.

According to the CDC, although asthma has no cure, it can usually be controlled with medications and by avoiding triggers that can cause attacks. For this reason, long-term management is often necessary to control symptoms and prevent flare-ups.
