Asthma is a chronic condition that causes breathing difficulties. The airways narrowing and swelling result in these difficulties. mucus can be produced in your airways if you have asthma. Asthma can cause coughing, wheezing, and other symptoms.

Asthma can be mild and need little or no medical treatment. However, it can also be severe and life threatening.

Chronic asthma is classified into four different types. The types are determined by the severity of your asthma symptoms, along with the results of objective testing, such as a spirometer.

An asthma attack is also known as an acute asthma exacerbation. Asthma attacks are usually short-lived. Some asthma-related terms are used to describe asthma types.

You can learn how chronic asthma is classified and some terminology used to describe asthma and the different types.

Chronic asthma classification

  • mild intermittent asthma
  • There is mild persistent asthma.
  • Moderate persistent asthma.
  • There is a severe persistent asthma.

Acute asthma terminology

  • Severe asthma.
  • asthma is life threatening
  • Near-fatal asthma.

Common asthma subtypes

  • asthma at night
  • Asthma work
  • allergic asthma
  • Nonallergic asthma.
  • Child- and adult-onset asthma.
  • There is seasonal asthma.
  • Exercise-induced asthma is also referred to as exercise-induced bronchoconstriction.
  • There is an asthma called eosinophilic.

Asthma itself is considered a chronic, or long-term, lung disease, where symptoms may come and go. However, chronic asthma describes cases where you experience asthma symptoms more regularly.

Symptoms and signs may include:

  • wheezing or whistling when breathing
  • coughing
  • The airways are swollen.
  • mucus in the lungs

The severity and control of asthma will be determined by the results of spirometry and peak flow meter tests, as well as how frequently you have symptoms. Asthma can change from one category to another.

Chronic asthma is classified into four categories, according to the National Institutes of Health (NIH) 2007 Guidelines for the Diagnosis and Management of Asthma. While these guidelines received an update in 2020, the classification of asthma severity was not changed.

Mild intermittent asthma

Mild intermittent asthma means you experience symptoms, such as wheezing and coughing, up to 2 days per week. You may also have asthma flareups at night up to twice per month.

Any asthma symptoms that occur more frequently than this are consideredpersistent.

Mild persistent asthma

As the least severe type of persistent asthma, having There is mild persistent asthma. means that you have symptoms greater than 2 days per week, but not daily. Nighttime symptoms can occur three to four times per month.

In There is mild persistent asthma., a person’s peak expiratory rate (PEF), a measure of their maximum speed of expiration, is greater than 80 percent of their predicted or personal best within the first second of breathing out, as measured with a peak flow meter. This test is performed when they are asymptomatic.

Moderate persistent asthma

With Moderate persistent asthma., you’re likely to experience symptoms every day. Asthma flare-ups may last several days, somewhat limiting your participation in daily activities. Those with Moderate persistent asthma. can experience sleep interference at night at least once per week, though not nightly.

In untreated Moderate persistent asthma., a person’s PEF falls within 60 to 80 percent, as measured during the first second of expiration using a peak flow meter.

Severe persistent asthma

Severe persistent asthma is the most serious, but least common form of chronic asthma. With this type of asthma, you experience symptoms throughout the day, every day.

Nighttime awakenings can occur 7 times a week. You may be limited to your daily activities.

When untreated, There is a severe persistent asthma. can lead to a PEF of less than 60 percent of predicted or personal best, as measured during the first second of expiration with a peak flow meter.

Most people with asthma will not develop chronic obstructive pulmonary disease (COPD), and many people with COPD don’t have asthma. However, it’s possible to have both.

ACOS occurs when someone has both asthma and COPD at the same time.

How is it treated?

Asthma treatment can improve symptoms, reduce the risk of hospitalization and loss of lung function, and minimize adverse effects from asthma medication.

Asthma management focuses on prevention. This can mean regular doctor visits.

  • Does you have symptoms?
  • Your lung function is monitored.
  • If needed, adjusts your medication.
  • Provides education.
  • discusses how to avoid triggering.

“People with mild intermittent asthma only need a rescue inhaler to treat their symptoms. You don’t usually need daily medication since your symptoms are only occasionally.”

If you are classified as having persistent asthma, chronic controller medications are usually necessary. It is important that people with asthma have immediate access to an bronchodilator that will relieve their asthma symptoms.

People with persistent asthma often need to take asthma medication daily. This can help keep their asthma under control, even if they do not experience daily symptoms. These medications are considered long-term control medications and they work by reducing inflammation in the airways.

Long-term control medications can be taken in an inhaler or in tablets.

The type of doctor you see can be related to your symptoms.

If your asthma is moderate to severe, you may be prescribed more than one medication.

If you have attacks, you will need another medication if one occurs. It is important to keep these medications on hand so you can treat symptoms.

For people with There is mild persistent asthma., a doctor may prescribe a low dose inhaled corticosteroid medication. An inhaled corticosteroid is taken by quickly inhaling it. It’s usually taken once or twice a day.

If you have asthma, the doctor may tell you to use your rescue inhaler before you exercise.

Often called an “asthma attack,” acute asthma refers to a sudden worsening of this lung disease, causing symptoms that can include:

These symptoms can also occur with or without long-term treatment. Acute asthma can be life threatening and require hospitalization, so rescue inhalers may be used during an attack.

The following terms may also be used to describe acute asthma flares.

Acute severe asthma

Acute severe asthma refers to a sudden onset of severe symptoms that you may experience throughout the day. This type of asthma is life threatening exacerbation may be caused by stopping your asthma treatment plan or an acute illness, such as an upper respiratory tract infection.

With an Severe asthma. attack, you may experience additional symptoms that can include:

  • fast breathing
  • Lying down makes it difficult to breathe.
  • sweating
  • fast heart rate
  • inability to talk or walk
  • There is confusion.

If you are experiencing any of the above symptoms, you should call the emergency services.

Life threatening asthma

In some cases, an acute asthma exacerbation may become life threatening. In fact, an estimated 25,000 to 50,000 people are admitted to intensive care every year in the United States due to asthma is life threatening.

Life threatening asthma can cause a significant drop in blood oxygen, a condition called hypoxemia, or too much carbon dioxide, which is known as hypercapnia. Both can be caused by inadequate respiration.

At the hospital, treatment typically includes bronchodilator medications to help open the airways and steroids to decrease inflammation. Intubation or mechanical ventilation may also be required.

Near-fatal asthma

Near-fatal asthma describes symptom exacerbation that can be deadly without hospitalization. While the exact causes may vary, risk factors may include:

  • having a history of Near-fatal asthma. attacks
  • Not taking your medication or stopping your treatment plan.
  • living in an urban environment
  • There is a lack of access to quality health care.
  • having other medical conditions such as cardiovascular disease

There are more than one type of asthma that can provide insights into your asthma. They can help you predict how you will respond to treatment.

Characterizing your asthma may help identify specific asthma attacks and help develop new treatments to help manage and prevent them.

It is important to discuss the subtypes with your doctor and follow the appropriate treatment plan for each.

Nocturnal asthma

Nocturnal asthma refers to symptoms that occur at night. Triggers may include allergens in your bedroom, cooling of the airway, heartburn, and hormone secretions that follow a circadian pattern.

Nighttime symptoms may include:

  • The chest is tight.
  • The breath was very thin.
  • cough
  • wheezing

These symptoms can make it hard to sleep and leave you tired.

Occupational asthma

Occupational asthma describes a type of asthma that develops as a result of regular exposure to substances at your place of work. These may include fumes, dust, and chemicals.

While it’s estimated that 15 percent of all new asthma cases are work related, Asthma work may take several years to develop in some people.

Allergic asthma

If you have allergies, you may be at a higher risk of developing asthma. The exact triggers for allergic asthma can vary but may include:

  • Pet dander.
  • Dust mite.
  • There is a lot of pollen.
  • There is a mold.
  • There are foods.

If you have a severe allergy, the severity of your asthma symptoms can be different.

Allergic asthma is the most common type of asthma and often requires treatment from an allergist or immunologist. Controlling your allergy symptoms and avoiding your triggers may help reduce future asthma attacks.

Aside from having a rescue inhaler on hand, allergic asthma treatments may include antihistamines, eye drops, leukotriene modifiers, and more.

Some people may benefit from allergy shots or be candidates for one of the biologic agents, such as anti-immunoglobulin E (anti-IgE) therapy. These therapies may help decrease asthma symptoms in people with severe asthma, according to a 2021 case study.

Nonallergic asthma

As the name suggests, nonallergic asthma is a type of asthma that is not related to an allergy trigger. This type of asthma may also be called nonatopic asthma.

Nonallergic asthma is less common than allergic asthma. Doctors don’t completely understand the causes of nonallergic asthma, but it often develops later in life. It may be more severe than allergic asthma.

Child- vs. adult-onset asthma

Asthma most often develops during childhood before the age of 5. This is referred to as childhood asthma or child-onset asthma. Up to 50 percent of children with asthma may experience improved asthma symptoms in early adulthood.

However, asthma can develop at any age. Asthma that starts during adulthood is called adult- or late-onset asthma, and it primarily affects women.

Seasonal asthma

Seasonal asthma describes exacerbations that you may experience with certain seasonal changes.

This may include outdoor seasonal allergens, such as There is a lot of pollen. or There is a mold.. It can also include weather pattern changes, such as wind, rain, and hot or cold air.

Exercise-induced asthma

Also called exercise-induced bronchoconstriction (EIB), this type of asthma occurs during or after exercise. While up to 90 percent of people with asthma have EIB, not everyone with EIB has chronic asthma.

Exercise-induced asthma may be managed with traditional asthma treatments and by taking your rescue inhaler 15 to 30 minutes before any vigorous activity.

Eosinophilic asthma

Eosinophilic asthma is a severe type of chronic asthma caused by an increase of eosinophil blood cells that may inflame and damage lung tissues. It typically develops in adulthood and may be treated with traditional asthma treatments.

However, if you have this type of asthma and it doesn’t respond to typical medications, your doctor may recommend biologics, a form of severe asthma treatment given by injection.

Educating yourself about your asthma condition is important in managing it.

Everyone with asthma should also have an asthma action plan. An asthma action plan is developed with a doctor and lists the steps that you need to take in case of an asthma attack.

If you have mild asthma, you should follow the treatment plan from the doctor and have regular checks.
