Every time you breathe in, air enters your nose and mouth. It flows down your throat and into a series of air passageways called bronchial tubes. Those tubes need to be open for the air to reach your lungs, where the oxygen is passed into the blood to be transported to your body's tissues.
If the airways are inflamed, air has more difficulty getting to your lungs. With less air getting in, you can feel short of breath. You may wheeze and cough in an attempt to draw in more oxygen through tightened passageways.
Asthma symptoms are like the weather -- they change often and may seem unpredictable. But also like the weather, careful tracking of asthma symptoms can help identify patterns and what they may say about your asthma control.
Research has shown that tracking and rating your asthma symptoms are key steps in successfully managing asthma. One study even found that it helps keep kids with childhood asthma out of the emergency room.
Most asthma action plans track your “peak flow” (measured by a portable,...
Bronchitis and asthma are two inflammatory airway conditions. Bronchitis is inflammation of the airways that is usually caused by viral or bacterial infections. Chronic bronchitis can be triggered by long-term exposure to environmental irritants such as tobacco smoke, dust, or chemicals.
Asthma is an inflammatory condition that leads to tightening of the muscles around the airways and swelling, which cause airways to narrow.
When the two conditions coexist, it is called asthmatic bronchitis.
What Causes Asthmatic Bronchitis?
There are many triggers that may initiate the release of inflammatory substances. Common asthmatic bronchitis triggers include:
Allergens such as pollen, mold, dust, pet dander, or food (and food additives like MSG)
The symptoms of asthmatic bronchitis are a combination of the symptoms of bronchitis and asthma.
You may experience some or all of the following symptoms:
Shortness of breath
Excess mucus production
You might wonder, is asthmatic bronchitis contagious? Bronchitis itself can be caused by a virus or bacteria, which are contagious. However, chronic asthmatic bronchitis typically is not contagious.
Visiting Your Doctor
If you've been experiencing symptoms like those listed above, make an appointment with your doctor. After going through a series of questions about your symptoms and taking a medical history and physical exam, your doctor may order tests such as:
Spirometry. A test that measures lung function as you breathe in and out of a mouthpiece that is attached to a device called a spirometer.
Peak expiratory flow. A test that measures the force of air you breathe out (exhale) into the mouthpiece of a device called a peak expiratory flow meter.
Chest X-ray. A radiology test that produces images of the chest to look for evidence of other conditions that could be causing your cough and breathing problems.
Treatments for Asthmatic Bronchitis
Asthmatic bronchitis treatments are essentially the same as those used to treat asthma and bronchitis, and may include:
