Asthma FAQ

What is asthma?

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, which can lead to difficulty breathing, coughing, and wheezing. The airways, or bronchial tubes, become irritated and swollen, and the muscles around them can tighten, making it harder for air to flow in and out of the lungs. This inflammation and constriction can cause symptoms such as difficulty breathing, chest tightness, and a whistling sound when breathing. Asthma can also cause episodes of wheezing, coughing, and shortness of breath, known as asthma attacks. These episodes can range from mild to severe and can be triggered by a variety of factors, including allergens, pollutants, stress, and respiratory infections. Asthma is a chronic disease, meaning it lasts a long time, and it can range in severity, it can vary from person to person and can fluctuate over time. People with asthma typically require ongoing medical care and management to control symptoms and prevent complications.

What causes asthma?

The exact cause of asthma is not fully understood, but it is believed to be a combination of genetic and environmental factors.

• Genetics: Asthma has been found to run in families, indicating that certain genetic factors may make a person more susceptible to the condition.
• Environmental triggers: Exposure to certain environmental triggers, such as allergens, pollutants, irritants and viral respiratory infections, can cause inflammation in the airways, and lead to asthma symptoms. Common environmental triggers include:

• Allergens such as pollen, mold, pet dander, and dust mites.
• Irritants such as cigarette smoke, air pollution, and strong odors or chemicals.
• Respiratory infections such as the flu or the common cold.

• Developmental Factors: Certain life events or changes in the environment during development may influence the development of asthma. For example, children who are exposed to second-hand smoke, or have lower birth weight, may have a higher risk of developing asthma.

It's important to note that asthma is a complex disease and not one specific thing causes it. The cause can be multifactorial, and what triggers asthma symptoms in one person might not affect another person. Identifying and avoiding triggers, as well as following a treatment plan, can help control the symptoms and prevent asthma attacks.

Is asthma a disease?

Yes, asthma is a chronic disease. It is a condition characterized by inflammation and narrowing of the airways in the lungs. This can cause difficulty breathing, chest tightness, and coughing, as well as episodes of wheezing and shortness of breath, known as asthma attacks. The inflammation and constriction of the airways can make it difficult for air to flow in and out of the lungs.

Asthma is considered a chronic disease because it is ongoing, with symptoms that can range from mild to severe, and can occur at different times in a person's life. It requires ongoing management and monitoring to control symptoms and prevent complications. Some people may have mild symptoms and only occasional asthma attacks, while others may have more frequent and severe symptoms that can be life-threatening.

Treatment of asthma typically involves identifying and avoiding triggers, taking medications as prescribed, and making lifestyle changes to help manage the condition. Asthma is a variable disease and management should be personalized. It's important to work with a healthcare provider to develop an asthma treatment plan that is appropriate for you.

Which is a trigger for an asthma attack?

An asthma trigger is anything that causes inflammation in the airways and causes asthma symptoms or an asthma attack. Triggers can be different for each person, and identifying and avoiding personal triggers is an important part of managing asthma. Some common triggers include:

• Allergens: Substances that can cause an allergic reaction, such as pollen, pet dander, mold, and dust mites.
• Irritants: Substances that can irritate the airways, such as cigarette smoke, air pollution, strong odors or chemicals, and perfumes.
• Respiratory infections: Virus such as the flu or the common cold, can trigger asthma symptoms.
• Weather changes: Cold air, high humidity, and thunderstorms can cause asthma symptoms.
• Stress: Emotional stress can cause the airways to constrict and trigger asthma symptoms.
• Exercise: Physical activity can cause airway constriction, this is known as exercise-induced asthma, which leads to symptoms such as wheezing, chest tightness, and shortness of breath.
• Gastroesophageal reflux disease (GERD): Stomach acid flowing back into the esophagus can cause asthma symptoms.
• Hormonal changes: Some women have asthma symptoms that worsen during their menstrual cycle.

It's important to note that not everyone with asthma will be affected by the same triggers, and identifying personal triggers can take time. Keeping a symptom diary can be a helpful tool in identifying triggers, it's also important to work with healthcare provider to develop a personalized plan to manage asthma.

Is asthma genetic?

Asthma does have a genetic component, meaning that there is a hereditary component to the risk of developing the disease. Studies have shown that if one parent has asthma, the child has a higher chance of developing asthma, and if both parents have asthma, the risk is even higher. It is thought that certain genetic variations may make a person more susceptible to the disease, or may influence the way the airways respond to triggers.

However, genetics is only one aspect of the disease. Even if a person has a genetic predisposition to asthma, it does not necessarily mean they will develop the condition. Environmental factors also play a role in the development of asthma. Triggers such as allergens, irritants, and respiratory infections can cause inflammation in the airways, leading to asthma symptoms.

It's important to note that asthma is a complex disease, and the interplay of genetic and environmental factors is not fully understood yet. The best way to know the causes of asthma, is by working with a healthcare professional to identify the specific triggers, and develop an appropriate treatment plan.

Is asthma a disability?

Asthma can be considered a disability because it can significantly impact a person's ability to perform daily activities and can restrict their participation in work, school, or other areas of life. The symptoms of asthma, such as difficulty breathing, chest tightness, and coughing, can range from mild to severe and can occur unexpectedly, making it difficult to predict and plan for them.

In many countries, including the United States and Canada, asthma can qualify as a disability under certain laws and policies, such as the Americans with Disabilities Act (ADA) and the Canadian Human Rights Act. Under these laws, individuals with asthma may be eligible for accommodations and protection from discrimination in the workplace, education and other areas of life.

It's important to note that not all people with asthma will have the same level of difficulty in performing daily activities, and some may have milder forms of the disease and will not be affected in the same way as others. The severity of asthma can also vary over time and be affected by different triggers and stressors.

If you have asthma and it significantly impacts your ability to perform daily activities, it's important to work with your healthcare provider to develop a treatment plan that can help control your symptoms and improve your quality of life. If you feel your asthma is impacting your ability to work or participate in other areas of life, you can ask to speak with a Human Resources representative or a Disability Services Coordinator to learn more about available resources and accommodations that may be able to help.

What does asthma feel like?

The symptoms of asthma can vary from person to person and can range from mild to severe. Some common symptoms of asthma include:

• Shortness of breath: A feeling of not being able to catch your breath, or feeling like you can't take a deep breath. This can happen suddenly and can be accompanied by wheezing.
• Chest tightness: A squeezing or heavy feeling in the chest. This can occur alone or with other symptoms.
• Wheezing: A whistling sound when breathing, usually heard when exhaling but can also be heard when inhaling.
• Coughing: A persistent dry or wet cough, especially at night or early in the morning.
• Difficulty breathing: A feeling that you can't get enough air into your lungs, and a sense of not being able to breathe out fully.
• Fatigue: Asthma can make it difficult to breathe, and this can lead to fatigue or a feeling of weakness.
• Trouble sleeping: Difficulty sleeping due to coughing, wheezing, or shortness of breath.
• Trouble during exercise: Some people may experience asthma symptoms during or after physical activity, this is known as exercise-induced asthma.

It's important to note that symptoms can vary and not everyone with asthma will experience all of these symptoms. It's also important to keep in mind that asthma symptoms can come and go, they may be more severe at some times and less severe at other times, depending on the triggers and the person's management plan. It's important to work with a healthcare provider to develop an asthma treatment plan that can help control symptoms and improve the quality of life.

How to prevent asthma?

Preventing asthma attacks and managing asthma symptoms requires a combination of avoiding triggers, taking medications as prescribed, and making lifestyle changes. Here are a few strategies that can help prevent asthma attacks:

• Identify and avoid triggers: Common triggers for asthma include allergens such as pollen and pet dander, irritants such as cigarette smoke and air pollution, and certain medications. Identifying and avoiding your personal triggers can help to prevent asthma symptoms and attacks.
• Follow a preventive medication plan: Long-term control medications such as inhaled corticosteroids can help to reduce inflammation in the airways and prevent asthma symptoms. These medications should be taken as prescribed, even when you're feeling well.
• Keep track of symptoms: Keeping a daily diary of your asthma symptoms can help you and your healthcare provider track patterns and identify potential triggers. This can help to adjust the treatment plan accordingly.
• Get a flu shot: Respiratory infections such as the flu can trigger asthma symptoms, so it's important to get a flu shot every year to reduce the risk of infection.
• Stay active and maintain a healthy weight: Regular physical activity is important for overall health and can help to prevent asthma symptoms.
• Practice good hygiene: Practicing good hygiene can help prevent respiratory infections, which can be a

How is asthma diagnosed?

Asthma is typically diagnosed based on a combination of factors, including a person's medical history, symptoms, and the results of physical exams and tests. Here are some common methods used to diagnose asthma:

• Medical history: A healthcare provider will ask about a person's symptoms, such as wheezing, coughing, and shortness of breath, as well as any known triggers and any family history of asthma. They will also take into account the patient’s past medical history and medications.
• Physical exam: A healthcare provider will listen to the person's lungs using a stethoscope to check for wheezing, crackling, or other abnormal sounds. They will also look for signs of asthma, such as chest tightness and difficulty breathing.
• Lung function tests: The most common test to diagnose asthma is spirometry, a simple test that measures how much air a person can inhale and exhale, and how fast they can exhale. A healthcare provider may also use a peak flow meter, which measures how fast a person can blow air out of their lungs.
• Allergy tests: Some people with asthma have allergies, which can trigger asthma symptoms. Allergy tests, such as skin prick tests or blood tests, can help identify any allergies that may be contributing to asthma symptoms.
• Imaging tests: In some cases, healthcare provider may order an imaging test such as chest x-ray or CT scan, to check for other conditions that might be causing symptoms similar to asthma, or to determine the condition of the lungs.

How to treat asthma?

Treatment for asthma aims to reduce inflammation in the airways, prevent asthma symptoms and attacks, and improve overall lung function. There are two main types of asthma treatment: quick-relief (or rescue) medications and long-term control medications.

• Quick-relief (or rescue) medications: These medications, such as albuterol, are taken as needed to relieve symptoms during an asthma attack or flare-up. They work by opening up the airways, making it easier to breathe.
• Long-term control medications: These medications are taken daily to reduce inflammation in the airways and prevent asthma symptoms from occurring. They include:

• Inhaled corticosteroids: These medications are the most effective long-term control medication for reducing inflammation in the airways.
• Leukotriene modifiers: These medications help to prevent inflammation and asthma symptoms.
• Immunomodulators: These medications can help to prevent asthma attacks and are usually used in combination with other medications.
• Long-acting bronchodilators: These medications help to open up the airways and prevent symptoms. They can be used alone or in combination with inhaled corticosteroids.

• Combination inhalers: Some asthma medications come in a single inhaler that contains both a long-acting bronchodilator and an inhaled corticosteroid. These combination inhalers can be effective in controlling asthma symptoms.

It's important to work with a healthcare provider to develop an asthma treatment plan that is appropriate for you. This plan should include a schedule of medications, a plan for monitoring symptoms, and guidelines for managing and preventing asthma attacks. Regular check-

It is important to work with a healthcare provider to determine the most appropriate treatment plan for your individual needs. They can help you weigh the potential benefits and risks of different medications and identify any potential interactions with other medications you may be taking.

Which medication and treatment  is best for a particular individual will depend on their specific situation and any other medical conditions they may have. It is important to collaborate with your doctor to determine the best treatment plan for your needs.
