How common is asthma?
Asthma is one of the most common chronic conditions in the United States, impacting approximately 25 million people. So, if you live with asthma, you’re not alone! Here are some additional asthma facts:
Types of asthma
There are several different categories of asthma, all of which are treated uniquely. These categories can be divided into allergic and nonallergic asthma and by age of onset, like preschool, school age, and adult-onset.
Many asthma sufferers also have allergies and experience a type of asthma known as allergic asthma. Sometimes, otherwise healthy individuals will experience asthma during exercise, which is known as exercise-induced bronchoconstriction or, more commonly, as exercise-induced asthma.
Those who work in environments that contain fumes, gases, and other substances can also experience what is known as occupational asthma. Finally, millions of children develop asthma in their earliest years of development and have what is referred to as childhood asthma.
When diagnosed with asthma after the age of 20, it is defined as adult-onset asthma and is typically considered chronic.learn more
This triggered at certain times of the year depending on the allergens that are present. Most people with asthma also suffer from allergies.learn more
Asthma is one of the most common long-term diseases but with proper care and treatment, kids can live completely normal lives.learn more
Patients who experience asthma symptoms only after vigorous exercise do not have asthma but have Exercise-Induced Bronchoconstriction (EIB).learn more
Nonallergic asthma usually occurs after mid-life and is caused by recurrent respiratory tract infections.learn more
Severe asthma affects only 5 to 10% of people with asthma. Severe asthma is difficult to control with standard asthma treatments, but can still be managed with the help of an allergy specialist.learn more
Other types of asthma include:
- Aspirin-induced asthma
- Asthma-COPD overlap syndrome (ACOS)
- Brittle asthma
- Cough-variant asthma
- Eosinophilic asthma
- Nighttime asthma
- Steroid-resistant asthma
- Stress-induced asthma
The symptoms of asthma can vary widely from one patient to the next. Signs of asthma can also look very different in children as compared to adults.
- Shortness of breath
- Chronic coughing
- Lack of sleep due to wheezing and/or coughing
- Tightening or pain in the chest
Asthma attack symptoms
An asthma attack is also known as an asthma exacerbation, meaning that your normal symptoms during an asthma flare-up will worsen and intensify suddenly. Signs of an asthma attack can include:
- A pale face
- Feelings of anxiety or panic
- Blue lips and fingertips
- Severe shortness of breath
- Severe chest tightness or pressure
- Intense coughing or wheezing
- A rattling sound in the chest
- Symptoms that don’t respond to a quick-acting inhaler
How long does an asthma attack last?
Asthma flare-up durations depend on what triggered the asthma attack, as well as how long the airways have been inflamed. On average:
- Mild episodes will last a few minutes and may be spontaneous. Often, these can be resolved with quick-acting medicine.
- Severe episodes can last hours to days. The right treatment can shorten these episodes.
What is an asthma attack, exactly?
Asthma affects the lungs by causing inflammation in the bronchial tubes. During an asthma attack, this inflammation increases and can be exacerbated by a tightening of the muscles around the airways.
Attacks can happen in the presence of allergens, like pollen, pet dander and dust mites, and non-allergic triggers, including pollution and smoke. Very cold temperatures, stress, and exercise can all trigger an attack, as well.
How is asthma treated?
There is no known cure for asthma. Patients, however, can control the symptoms of asthma using a range of medications. Controller medications for asthma can be both inhaled and oral medications, including:
- Corticosteroids (fluticasone, mometasone, ciclesonide)
- Long-acting beta-agonists, or LABAs
- Leukotriene modifiers (oral medication)
In some severe cases, patients may need injections or infusions known as biologics.
For quick relief from symptoms during an asthma attack, patients can use short-acting beta-agonists such as albuterol, pirbuterol, and levalbuterol. It is important to note that these are quick-relief medications and should not be used in place of controller medications. Additionally, if a patient requires quick relief medications more than twice a week, it may be necessary to make adjustments to a patient’s prescribed controller medications.
As a chronic condition, asthma also requires ongoing management and careful adherence by the patient to asthma treatment guidelines. This involves not only taking medication on a regular and consistent basis, but also engaging in lifestyle choices that help manage asthma in the long term. Patients with asthma should avoid smoking and avoid known triggers such as allergens, pollution, etc.
Frequently asked questions
What’s the best treatment for asthma?
The fastest relief option during an asthma attack typically involves using an inhaler with short-acting beta-agonists such as albuterol, pirbuterol, and levalbuterol. However, this is not a replacement for long-term controller medications. If you’re suffering from chronic asthma, speak with your doctor about the most effective long-term treatment options.
Can asthma go away on its own?
As a chronic condition, asthma does not typically resolve on its own. In some cases of childhood asthma, asthma can disappear as the patient gets older. When a case of asthma is severe in a child, the patient will not typically ‘outgrow’ it.
Are there home remedies for asthma?
There are a range of popular home remedies that anecdotally have an effect on asthma, including essential oils and diuretics such as coffee and tea. These are not replacements for medications, however, and any home remedy undertaken should be done in consultation with your allergist or doctor.
How do allergies affect asthma?
Allergies are some of the most common triggers of asthma. Anyone with asthma and known allergies should limit or eliminate all exposure to allergens, as they can trigger asthma flare-ups.
