Symptoms of Asthma

Asthma Introduction

Asthma is a chronic respiratory condition that affects the airways, making it difficult for individuals to breathe properly. It is a common condition worldwide, and its prevalence has been increasing over the years. Asthma can occur at any age, although it often begins in childhood. It affects people of all races and genders.

The exact cause of asthma is not fully understood, but it is believed to result from a combination of genetic and environmental factors. Individuals with a family history of asthma or allergies are more likely to develop the condition. Environmental factors such as exposure to allergens (e.g., pollen, dust mites, pet dander), air pollution, respiratory infections, and tobacco smoke can trigger or worsen asthma symptoms.

While there is no cure for asthma, it can be managed effectively with proper treatment and self-care. The primary goals of asthma treatment are to control symptoms, prevent asthma attacks, and maintain good lung function. Treatment plans often include the use of inhalers, which deliver medication directly to the airways to relieve symptoms and reduce inflammation. Other treatment options may include oral medications, allergy management, and lifestyle modifications.

What is Asthma?

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, shortness of breath, and chest tightness. It is a common condition that affects people of all ages, and its severity can range from mild to severe.

By properly managing asthma, individuals can lead active and fulfilling lives, with minimal impact from their condition. Education, self-care, and adherence to the prescribed treatment plan are key to achieving good asthma control and preventing complications.

What types of asthma are there?

Asthma is broken down into types based on the cause and the severity of symptoms. Healthcare providers identify asthma as:

Intermittent: This type of asthma comes and goes so you can feel normal in between asthma flares.
Persistent: Persistent asthma means you have symptoms much of the time. Symptoms can be mild, moderate or severe. Healthcare providers base asthma severity on how often you have symptoms. They also consider how well you can do things during an attack.
Asthma has multiple causes:

Allergic: Some people’s allergies can cause an asthma attack. Allergens include things like molds, pollens and pet dander.
Non-allergic: Outside factors can cause asthma to flare up. Exercise, stress, illness and weather may cause a flare.
Asthma can also be:

Adult-onset: This type of asthma starts after the age of 18.
Pediatric: Also called childhood asthma, this type of asthma often begins before the age of 5, and can occur in infants and toddlers. Children may outgrow asthma. You should make sure that you discuss it with your provider before you decide whether your child needs to have an inhaler available in case they have an asthma attack. Your child’s healthcare provider can help you understand the risks.

In addition, there are these types of asthma:

Exercise-induced asthma: This type is triggered by exercise and is also called exercise-induced bronchospasm.
Occupational asthma: This type of asthma happens primarily to people who work around irritating substances.
Asthma-COPD overlap syndrome (ACOS): This type happens when you have both asthma and chronic obstructive pulmonary disease (COPD). Both diseases make it difficult to breathe.


Symptoms of asthma can vary from person to person and may occur intermittently or persistently. Some common symptoms include:

  1. Wheezing: A whistling or squeaky sound when breathing, caused by narrowed airways.
  2. Coughing: Often worse at night or early morning, and can be triggered by exercise or exposure to allergens.
  3. Shortness of breath: Difficulty breathing or a feeling of breathlessness, often accompanied by a sense of tightness in the chest.
  4. Chest tightness: A sensation of pressure or constriction in the chest.

Asthma treatment aims to control symptoms, prevent flare-ups (asthma attacks), and maintain good lung function. The primary treatment options include:

  1. Inhalers: Inhalers are the cornerstone of asthma management. There are two main types:
    • Rescue Inhalers (Short-acting bronchodilators): These provide quick relief during an asthma attack by relaxing the muscles around the airways, allowing them to open up and ease breathing.
    • Controller Inhalers (Long-acting bronchodilators and corticosteroids): These are used daily to reduce inflammation and prevent symptoms. They help keep the airways open and decrease the frequency and severity of asthma attacks.
  2. Allergy management: For individuals with allergic asthma, identifying and avoiding triggers such as pollen, dust mites, pet dander, or certain foods can help prevent symptoms. In some cases, allergy shots (immunotherapy) may be recommended to reduce sensitivity to specific allergens.
  3. Medications: Besides inhalers, other medications such as oral corticosteroids, leukotriene modifiers, and mast cell stabilizers may be prescribed to manage severe or persistent asthma.
  4. Lifestyle modifications: Making certain lifestyle changes can contribute to asthma management. These include maintaining a healthy weight, exercising regularly (with proper warm-up and cool-down periods), avoiding smoking and exposure to secondhand smoke, managing stress levels, and ensuring good indoor air quality.
Asthma Inhaler

An asthma inhaler is a medical device used to deliver medication directly into the lungs to relieve asthma symptoms and manage the condition. Inhalers are portable, handheld devices that allow the medication to be inhaled as a mist or spray, reaching the airways directly.

There are two main types of inhalers used in asthma management:

  1. Rescue Inhalers (Short-acting bronchodilators): These inhalers provide quick relief during asthma attacks or when symptoms arise. They contain a medication called a bronchodilator, which works by relaxing the muscles around the airways, opening them up, and allowing easier airflow. The most common type of rescue inhaler contains a medication called albuterol (salbutamol). These inhalers provide immediate relief of symptoms and are often referred to as “reliever” or “quick-relief” inhalers.
  2. Controller Inhalers (Long-acting bronchodilators and corticosteroids): These inhalers are used on a regular basis to control asthma symptoms and prevent flare-ups. They contain medications that help reduce inflammation and keep the airways open over an extended period. Controller inhalers are usually prescribed for individuals with persistent asthma or those who require ongoing management. They may contain long-acting bronchodilators, corticosteroids, or a combination of both.

It’s important to use inhalers correctly to ensure proper delivery of medication. Here are some general steps for using an inhaler:

  1. Shake the inhaler: If instructed, shake the inhaler to mix the medication properly.
  2. Prepare the inhaler: Remove the cap and check if the inhaler is clean and not expired.
  3. Breathe out: Exhale fully to prepare for inhalation.
  4. Form a seal: Hold the inhaler with the mouthpiece at the bottom and form a seal around it with your lips or use a spacer device if provided.
  5. Activate the inhaler: Press down on the inhaler to release a dose of medication while simultaneously inhaling slowly and deeply through your mouth. The timing may vary depending on the specific inhaler, so follow the instructions provided by your healthcare provider.
  6. Hold breath and exhale: After inhalation, hold your breath for a few seconds to allow the medication to reach deep into the lungs. Then exhale slowly.
  7. Repeat if necessary: If instructed or if multiple doses are required, wait for the recommended time between doses and repeat the process.

Remember to clean and maintain your inhaler regularly as per the manufacturer’s instructions. If you have any doubts about the correct technique or usage, consult your healthcare provider or pharmacist for guidance.

It’s essential to have open communication with your healthcare provider to ensure you have the appropriate inhaler, understand how to use it correctly, and have a clear understanding of your asthma action plan.

More On Asthma

Here’s some additional information on asthma:

Triggers: Asthma symptoms can be triggered by various factors, including allergens (pollen, dust mites, mold, pet dander), irritants (tobacco smoke, air pollution, strong odors), respiratory infections (colds, flu), exercise, cold air, stress, and certain medications.

Diagnosis: To diagnose asthma, healthcare providers consider a person’s medical history, symptoms, and perform various tests. These may include lung function tests, such as spirometry, which measures the amount of air a person can exhale forcefully, and peak flow monitoring, which measures how well air moves out of the lungs. Allergy testing may also be done to identify specific triggers.

Asthma Action Plan: An asthma action plan is a written document that outlines personalized instructions for managing asthma. It usually includes information about daily medications, rescue inhaler use, steps to take during worsening symptoms or asthma attacks, and emergency contacts. Following the action plan can help individuals take appropriate measures and seek medical assistance when needed.

Emergency Situations: Severe asthma attacks can be life-threatening and require immediate medical attention. Signs of a severe attack include extreme difficulty breathing, rapid breathing, chest pain or pressure, bluish lips or fingernails, and a lack of improvement with rescue inhaler use. In such cases, it is important to call emergency services or go to the nearest emergency room.

Asthma and Children: Asthma is a common condition in children, and management strategies may differ based on age. Parents or caregivers of children with asthma should work closely with healthcare providers to understand their child’s treatment plan, proper inhaler technique, and how to recognize and respond to worsening symptoms.

Asthma Research and Support: Ongoing research aims to improve asthma treatment and management. Organizations such as the American Lung Association, Asthma and Allergy Foundation of America, and Global Initiative for Asthma provide educational resources, support, and advocacy for individuals with asthma and their families.

Remember, it is crucial for individuals with asthma to work with healthcare providers to develop an individualized treatment plan. Regular communication, adherence to medications, and avoiding triggers can significantly help in managing asthma and leading a healthy, active life.


In conclusion, asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways. It can cause symptoms such as wheezing, coughing, shortness of breath, and chest tightness. While the exact cause of asthma is not fully understood, it is believed to result from a combination of genetic and environmental factors.
