What is Asthma? Types of Asthma and Asthma Triggers

Asthma is a chronic respiratory disease that affects millions of people worldwide. It is a condition in which the airways narrow and become inflamed, leading to difficulty in breathing. While asthma cannot be cured, it can be managed with the right treatment and care. 

At healthcare nt sickcare, we understand the impact of asthma on your life and offer comprehensive diagnostic and treatment options for asthma.

In this blog post, we will discuss the various aspects of asthma, including its symptoms, triggers, types, and treatment options. We will also answer some of the most common questions related to asthma.

What is Asthma?

Asthma is a chronic respiratory condition in which the airways narrow and become inflamed, leading to difficulty in breathing. The inflammation of the airways causes the muscles around them to tighten, making it harder to breathe. This can result in coughing, wheezing, chest tightness, and shortness of breath.

What are the Signs and Symptoms of Asthma?

The symptoms of asthma vary from person to person. Some common signs of asthma include coughing, wheezing, chest tightness, and shortness of breath. Some people may experience these symptoms only during exercise, while others may have them all the time. In severe cases, asthma can lead to respiratory failure, which can be life-threatening.

What are the Various Types of Asthma?

There are several types of asthma, including:

1. Allergic asthma: This type of asthma is triggered by allergens such as pollen, dust mites, and pet dander.
2. Eosinophilic asthma: This is a severe form of asthma that is characterized by high levels of eosinophils (a type of white blood cell) in the airways.
3. Exercise-induced asthma: This type of asthma is triggered by physical activity or exercise.
4. Cough-variant asthma: This type of asthma is characterized by a persistent cough, but little or no wheezing.
5. Cardiac asthma: This type of asthma is caused by heart failure.
6. Severe asthma: This is a more severe form of asthma that is difficult to control with standard treatment.

Asthma Triggers

Asthma triggers are substances or situations that can cause asthma symptoms to worsen. Some common asthma triggers include:

1. Allergens such as pollen, dust mites, and pet dander.
2. Irritants such as smoke, pollution, and chemical fumes.
3. Respiratory infections such as colds and the flu.
4. Exercise or physical activity.
5. Emotional stress.
6. Changes in weather or temperature.

Asthma Exacerbation

Asthma exacerbation refers to a sudden worsening of asthma symptoms. It can be caused by several factors, including exposure to allergens or irritants, respiratory infections, or failure to take medication as prescribed. It is important to seek medical attention if you experience an asthma exacerbation.

How to Test for Asthma?

Asthma causes swelling and narrowing of the bronchial airways, leading to wheezing, coughing, chest tightness and shortness of breath. Various tests help diagnose asthma and assess severity.

Medical History

Doctors assess symptoms, family history of asthma or allergies, environmental exposures and other risk factors to guide testing.

Physical Exam

Examining breathing rate, chest sounds, nose and throat inflammation provides clinical clues about asthma likelihood.

Spirometry

This breathing test measures air volume, flow and lung capacity. Patients blow into a mouthpiece to determine lung function before and after bronchodilators to confirm asthma.

Peak Flow Meter

This handheld tool measures peak expiratory flow rate, which is reduced with asthma. Values improve after using a bronchodilator if asthma is present.

Methacholine Challenge

This test provokes bronchoconstriction with a small dose of methacholine and measures airflow changes. Reduction in lung function indicates hyperreactive airways typical of asthma.

Allergy Testing

Allergies often trigger asthma flares. Skin or blood tests identify specific allergic triggers like dust, pets, pollen to better treat and manage asthma.

Chest X-ray

X-rays help rule out other lung diseases or complications. Asthma itself does not show definitive changes on X-rays.

Sputum Analysis

Examining sputum samples under a microscope looks for increased inflammatory cells like eosinophils which are elevated in asthma.

Diagnostic testing from multiple angles provides the clearest assessment of asthma presence, triggers and severity. Accurate testing leads to better asthma control.

Asthma Treatment

Asthma treatment typically involves a combination of medication and lifestyle changes. Medications used to treat asthma include:

1. Inhalers: These are devices that deliver medication directly to the airways.
2. Corticosteroids: These are anti-inflammatory medications that help reduce inflammation in the airways.
3. Leukotriene modifiers: These medications help prevent inflammation and swelling in the airways.
4. Immunomodulators
5. Bronchodilators: These medications help relax the muscles around the airways, making it easier to breathe.
6. Biologics: These are targeted medications that block specific pathways involved in the inflammation of the airways.

Lifestyle Change to Curb Asthma

In addition to medication, lifestyle changes can also help manage asthma symptoms. These include:

1. Avoiding asthma triggers.
2. Maintaining a healthy weight.
3. Exercising regularly.
4. Managing stress.
5. Getting enough sleep.
6. Using a peak flow meter to monitor lung function.

Home Remedies for Asthma

While medication and lifestyle changes are essential for managing asthma, some home remedies may also help alleviate symptoms. These include:

1. Breathing exercises: Deep breathing exercises such as yoga and meditation can help improve lung function and reduce stress.
2. Steam inhalation: Inhaling steam can help open up the airways and relieve congestion.
3. Honey: Honey has anti-inflammatory properties that may help reduce inflammation in the airways.
4. Ginger: Ginger has anti-inflammatory properties that may help reduce inflammation in the airways.
5. Omega-3 fatty acids: Omega-3 fatty acids found in fish and nuts have anti-inflammatory properties that may help reduce inflammation in the airways.
6. Eucalyptus oil: Eucalyptus oil has a soothing effect on the airways and can help alleviate symptoms.

Yoga for Asthma

Yoga is a popular form of exercise that can be helpful for people with asthma. Yoga can help improve lung function, reduce stress, and improve overall fitness. Some yoga poses that may be beneficial for people with asthma include:

1. Pranayama: This is a breathing exercise that involves deep breathing and can help improve lung function.
2. Sukhasana: This is a seated pose that can help reduce stress and improve overall well-being.
3. Bhujangasana: This is a pose that involves lying on the stomach and raising the chest, which can help open up the airways.
4. Setu Bandhasana: This is a pose that involves lying on the back and raising the hips, which can help improve lung function.

Asthma Diet

Asthma is a chronic respiratory condition that affects millions of people worldwide. While medications and other treatments can help manage symptoms, a healthy diet may also play a role in managing asthma. Here's what you need to know about an asthma-friendly diet.

Asthma and Inflammation

Asthma is characterized by chronic inflammation of the airways, which can make it difficult to breathe. While there is no specific "asthma diet" that can cure the condition, there are foods that may help reduce inflammation and support overall respiratory health.

Foods to Include in an Asthma-Friendly Diet

1. Fruits and vegetables: Fruits and vegetables are rich in antioxidants and other nutrients that can help reduce inflammation and support respiratory health. Some particularly beneficial fruits and vegetables include apples, berries, spinach, and kale.
2. Omega-3 fatty acids: Omega-3 fatty acids, found in foods like salmon, walnuts, and flaxseed, have been shown to have anti-inflammatory effects and may help reduce asthma symptoms.
3. Magnesium-rich foods: Magnesium is an important nutrient that can help relax the muscles in the airways, making it easier to breathe. Foods like almonds, spinach, and avocado are rich in magnesium.
4. Vitamin D: Vitamin D plays a role in immune system function and may help reduce inflammation. Foods like fatty fish and fortified dairy products are good sources of vitamin D.
5. Herbal teas: Some herbal teas, like ginger tea and chamomile tea, have anti-inflammatory properties and may help reduce asthma symptoms.

Foods to Avoid or Limit

1. Processed foods: Processed foods, like fast food and packaged snacks, are often high in saturated and trans fats, which can promote inflammation and worsen asthma symptoms.
2. Dairy products: Some individuals with asthma may be sensitive to dairy products, which can trigger inflammation and worsen symptoms. If you suspect that dairy products may be affecting your asthma, try eliminating them from your diet for a few weeks to see if symptoms improve.
3. Sulfites: Sulfites are a preservative commonly found in wine, dried fruit, and other processed foods. Some individuals with asthma may be sensitive to sulfites, which can trigger asthma symptoms.
4. High-sugar foods: High-sugar foods like candy and soda can promote inflammation and worsen asthma symptoms.

Asthma in COVID-19

Due to the ongoing COVID-19 pandemic, there has been growing concern about the impact of the virus on individuals with asthma. While individuals with asthma are not at a higher risk of contracting COVID-19, they may be at a higher risk of developing severe symptoms if they do contract the virus. Here's what you need to know about asthma and COVID-19.

Asthma and COVID-19

What You Need to Know According to the Centers for Disease Control and Prevention (CDC), individuals with moderate to severe asthma may be at higher risk of developing severe symptoms if they contract COVID-19. This is because COVID-19 primarily affects the respiratory system, which can be particularly problematic for individuals with respiratory conditions like asthma.

It's important to note that having asthma does not necessarily mean that you are at higher risk of contracting COVID-19. However, if you do contract the virus, you may experience more severe symptoms than someone without asthma.

Symptoms of COVID-19 in individuals with asthma may include:

• Shortness of breath
• Chest tightness
• Coughing
• Wheezing
• Difficulty breathing

If you experience any of these symptoms, it's important to seek medical attention right away.

Preventing COVID-19 in Individuals with Asthma

Preventing COVID-19 is critical for individuals with asthma, as they may be at higher risk of developing severe symptoms if they contract the virus. Some steps you can take to prevent COVID-19 include:

1. Getting vaccinated: The COVID-19 vaccine is available for eligible individuals and has been shown to be safe and effective at preventing severe illness, hospitalization, and death from COVID-19.
2. Practicing good hand hygiene: Wash your hands frequently with soap and water for at least 20 seconds, or use hand sanitizer if soap and water are not available.
3. Wearing a mask: Wear a mask when in public settings, especially when you are unable to maintain a safe distance from others.
4. Avoiding large crowds: Avoid large gatherings and crowded indoor spaces whenever possible.
5. Maintaining physical distance: Stay at least 6 feet away from others whenever possible.

Managing Asthma during the COVID-19 Pandemic

In addition to taking steps to prevent COVID-19, it's important for individuals with asthma to continue managing their condition during the pandemic. This may include:

1. Taking your asthma medication as prescribed: It's important to continue taking your asthma medication as prescribed, even during the pandemic.
2. Avoiding asthma triggers: Try to avoid asthma triggers whenever possible, as they can worsen asthma symptoms and make it harder to breathe.
3. Monitoring your asthma symptoms: Keep track of your asthma symptoms and contact your healthcare provider if you experience any changes or worsening symptoms.
4. Creating an asthma action plan: Work with your healthcare provider to create an asthma action plan that outlines what to do in case of an asthma attack or worsening symptoms.

What triggers an asthma attack?

Common asthma attack triggers include respiratory infections, pollen, pet dander, mold spores, smoking, cold air, exercise, air pollution, harsh fumes and scents. Stress and some medications can also trigger flares by worsening inflammation. Identifying personal triggers helps prevention.

What is the difference between COPD and asthma?

While COPD and asthma both cause breathing issues and chest tightness, COPD is non-reversible lung damage from smoking or pollution whereas asthma causes reversible but uncontrolled airway inflammation. Medications relieve rather than cure asthma allowing symptom-free periods unlike COPD.

Can asthma inhalers cause weight gain?

Some asthma medications like oral steroids have weight gain as a side effect by increasing appetite. However preventative long-term asthma control inhalers like ICS, LABA or combination products have not shown definitive links to causing weight changes. Their anti-inflammatory action can help exercise easier.

Is asthma considered a disability?

Yes, uncontrolled severe asthma that remains symptomatic and interferes with normal activity despite appropriate treatment is considered a disabling condition under laws like the ADA in the United States. Work accommodations may be allowed to help manage asthma disability.
