Do you ever feel like it is hard to breathe? Perhaps you have a tight feeling in your chest, or you find yourself coughing frequently at night? These could be symptoms of Asthma. At Nirogi Lanka, we want to help you understand what asthma is, why it occurs, and how you can manage it effectively.
What is Asthma?
Simply put, asthma is a condition that affects your airways. Often referred to as 'bronchial asthma,' it is a chronic condition. This means it is long-lasting and requires ongoing medical care, as there is no immediate 'cure' that makes it vanish forever. Asthma is common, affecting both children and adults. If not managed properly, it can become a life-threatening emergency, which is why your awareness and proactive management are so important.
What is an Asthma Attack?
When you breathe normally, the muscles around your airways remain relaxed, allowing air to flow in and out easily. However, during an asthma attack, three key changes occur:
- Bronchospasm: The muscles wrapping around your airways tighten, narrowing the space and making it difficult for air to move.
- Inflammation: The lining of your airways becomes swollen, further reducing the amount of air that can reach your lungs.
- Mucus Production: Your body produces excess mucus, which clogs your airways and obstructs airflow.
As your airways narrow, you may hear a whistling sound when you exhale. This is known as Wheezing. An asthma attack—also referred to as an 'exacerbation' or 'flare-up'—is a sign that your asthma is not currently under control.
Are there different types of Asthma?
Yes, asthma is classified based on the cause and severity of symptoms. Doctors typically categorize it as:
- Intermittent Asthma: Symptoms come and go. You may feel perfectly fine between flare-ups.
- Persistent Asthma: You experience symptoms more regularly. The severity can range from mild to moderate or severe, which your doctor determines by how often you have symptoms and how much they interfere with your daily life.
Asthma triggers can vary significantly:
- Allergic Asthma: Triggered by allergies to substances like molds, pollens, or pet dander.
- Non-allergic Asthma: Triggered by external factors such as exercise, stress, illnesses, or weather changes.
Asthma can also be categorized by the stage of life or environment:
- Adult-onset Asthma: Asthma that develops after age 18.
- Pediatric Asthma: Also called 'childhood asthma,' this often starts before age 5. While some children outgrow it, it is vital to work with your pediatrician to create an action plan, keep an inhaler handy, and know exactly what to do during an attack.
Other specific types include:
- Exercise-induced Asthma: Flares up during physical activity, also known as exercise-induced bronchospasm.
- Occupational Asthma: Caused by exposure to irritating substances in your workplace, such as in factories or agricultural settings.
- Asthma-COPD Overlap Syndrome (ACOS): This occurs when you have both asthma and Chronic Obstructive Pulmonary Disease (COPD), both of which restrict your breathing.
Who can get Asthma?
Asthma can affect anyone at any age. However, those with existing allergies and people exposed to tobacco smoke are at a higher risk. This includes 'secondhand smoke' (inhaling smoke from others) and 'thirdhand smoke' (residue on clothes and furniture). Protecting children from smoke exposure is essential. Women are also statistically more prone to asthma, and prevalence can vary by ethnicity.
What causes Asthma?
While researchers are still working to understand exactly why some people develop asthma and others do not, several risk factors have been identified:
- Allergies: If you suffer from allergies, your risk of developing asthma is significantly higher.
- Environmental factors: Some people develop asthma after exposure to substances that irritate the airways. These include allergens, toxins, various types of smoke, and the previously mentioned ‘second-hand’ or ‘third-hand’ smoke. These are particularly harmful to infants and young children whose immune systems are still developing.
- Genetics: If anyone in your family has asthma or allergic conditions, you are at a higher risk of developing asthma as well. In short, it can run in families.
- Respiratory infections: Certain respiratory infections, such as the Respiratory Syncytial Virus (RSV), can damage the developing lungs of young children, which may lead to the development of asthma later in life.
What are the common triggers for an asthma attack?
An asthma attack can occur if you come into contact with substances that irritate or provoke your airways. Doctors call these ‘triggers.’ Once you identify what specifically worsens your asthma, it becomes easier to avoid potential attacks.
For some, an attack can happen immediately upon exposure to a trigger. For others, symptoms might start hours or even days later.
Triggers can vary from person to person, but here are some common ones:
- Air pollution: Many outdoor factors can worsen asthma, including factory smoke, vehicle exhaust, and smoke from wildfires.
- Dust mites: These are microscopic creatures living in our homes. If you have an allergy to dust mites, they can trigger an asthma attack. They are especially prevalent in old mattresses, pillows, and carpets.
- Exercise: For some individuals, physical activity can trigger an attack.
- Mold: Mold thrives in damp areas. If you have asthma, mold can cause significant problems. You do not necessarily need to be allergic to mold for it to trigger an attack.
- Pests: Pests like cockroaches and rodents can also contribute to asthma attacks.
- Pets: Your pets can be a trigger for an asthma attack. If you are allergic to ‘pet dander’ (tiny flecks of skin shed by animals), inhaling them can irritate your airways.
- Tobacco smoke: If you smoke or if someone in your household smokes, your risk of asthma increases. Never smoke in confined spaces like cars or inside the house. The best course of action is to quit smoking; your doctor can provide guidance on how to achieve this.
- Strong chemicals or smells: Certain perfumes, cleaning agents, and strong odors can worsen asthma symptoms for some people.
- Certain occupational exposures: You may be exposed to various substances at your workplace. Cleaning products, flour dust, wood dust, or other chemicals are examples. If you have asthma, these can all act as triggers.
What are the symptoms of asthma?
People with asthma typically show clear symptoms, many of which resemble respiratory infections:
- Feeling of chest tightness, pain, or pressure.
- Coughing (especially at night).
- Shortness of breath.
- Wheezing (a whistling sound while breathing).
When you have asthma, you may not experience every single symptom during every attack. Individuals with chronic asthma may show different symptoms at different times, and even the symptoms themselves can vary during the course of an attack.
How do doctors diagnose asthma?
Your doctor will review your medical history, including information about your parents and siblings. They will also ask about your specific symptoms, as well as any existing allergies, eczema (a skin condition causing rashes due to allergies), or other lung-related concerns.
Your doctor may recommend a spirometry test. This measures how quickly you can move air through your lungs. It is used to diagnose asthma and monitor your progress with treatment. Additionally, they may suggest a chest X-ray, blood tests, or skin allergy tests.
What are the treatments for asthma?
There are various options for managing your asthma effectively. Your doctor will prescribe medications to control your symptoms, which may include:
- Bronchodilators: These medications relax the muscles around your airways, allowing air to flow more easily. They also make it easier to clear mucus from the airways. These are used to provide quick relief when symptoms arise and are utilized for both intermittent and chronic asthma.
- Anti-inflammatory medicines: These reduce swelling and mucus production in your airways, making it easier for air to enter and exit your lungs. Your doctor may prescribe these as a daily maintenance medication to control or prevent chronic symptoms.
- Biologic therapies for asthma: These are used for severe asthma cases where symptoms persist despite the use of standard inhaler treatments.
There are several ways to take your asthma medication. You may need a metered-dose inhaler, a nebulizer, or another type of device to inhale the medication. In some cases, your doctor might also prescribe oral medications.
What is Asthma Control? by Nirogi Lanka
The primary goal of asthma treatment is symptom management. When we say your asthma is well-controlled, it means:
- You can perform your daily activities at home and work without interruption.
- You experience little to no asthma symptoms.
- You rarely need to rely on your rescue inhaler.
- You are able to sleep soundly without asthma symptoms waking you up.
Achieving these goals means your asthma is effectively managed, allowing you to lead a normal, active life.
How do you monitor asthma symptoms?
Keeping a record of your symptoms is a vital part of managing your condition. Your doctor may ask you to use a Peak Flow (PF) Meter. This device measures how forcefully you can exhale from your lungs. This data helps your doctor adjust your medication as needed and alerts you if your symptoms are beginning to worsen.
What is the outlook for someone with asthma?
Even with an asthma diagnosis, you can still lead a highly productive life and participate in sports and other activities. Do not be afraid. Your doctor will work with you to manage your symptoms, identify your specific triggers, and create strategies to prevent or manage asthma attacks effectively.
How can you prevent an asthma attack?
Once diagnosed, identifying your specific triggers is key. Avoiding these triggers is the best way to prevent an attack. While we cannot prevent the development of asthma itself, we can certainly prevent the episodes it causes.
What is an Asthma Action Plan?
Your doctor will create a personalized Asthma Action Plan with you. This plan details how and when to use your medications, how to respond to specific symptoms, and when to seek emergency care. If any part of your plan is unclear, please ask your doctor to explain it to you.
What to do in a severe asthma attack?
If you experience a severe asthma attack, you require immediate medical attention. In severe cases, patients may struggle to breathe to the point where their oxygen levels drop dangerously.
The first step is to use your rescue inhaler. These inhalers contain fast-acting medication that quickly opens your airways. This is distinct from your daily maintenance inhaler. If the attack is severe, you may need to use this more frequently according to your plan.
If your rescue inhaler does not help, or you do not have it, go to the nearest hospital emergency department immediately if you notice these symptoms:
- Severe anxiety or panic.
- Bluish tint to your fingernails or lips (or grey/white for darker skin tones).
- Chest pain or intense pressure.
- Uncontrollable coughing or severe wheezing.
- Difficulty speaking in full sentences.
- Pale, sweaty face.
- Rapid, labored breathing.
How do you know if you have asthma?
To confirm whether you have asthma or another condition, you must consult a doctor. Other respiratory conditions can mimic asthma symptoms like shortness of breath and wheezing. Please avoid self-diagnosis and rely on professional medical evaluation.
Is asthma curable?
No, there is currently no cure for asthma. However, it is highly manageable. In some cases, children may outgrow asthma as they reach adulthood.
Why does my asthma get worse at night?
Asthma that worsens at night is often referred to as Nocturnal Asthma. While the exact medical cause is not always clear, there are several contributing factors.
- Your Sleeping Position: Sleeping flat on your back can cause mucus to pool in your throat or trigger acid reflux, which can worsen asthma. Furthermore, lying flat puts pressure on your chest and lungs, potentially making it harder to breathe. Conversely, sleeping on your stomach or side can also sometimes exert pressure on your lungs.
- Bedroom and Evening Triggers: Your bedding, pillows, and pillowcases may harbor dust mites, mold, or pet dander. If you have been outdoors in the evening, you might have inadvertently brought pollen inside.
- Medication Side Effects: Certain asthma medications, such as some steroids and montelukast, can occasionally interfere with your sleep patterns.
- Air Temperature: Breathing in very hot air can cause your airways to narrow, while cold air acts as a significant asthma trigger for many individuals.
- Natural Lung Function Changes: It is a normal physiological process for lung function to naturally decline slightly during the night.
- Poor Daytime Asthma Control: If your asthma is not well-managed during the day, symptoms will likely persist or worsen at night. It is vital to work with your doctor to ensure your asthma is well-controlled both day and night. Treating nocturnal symptoms is critical; severe asthma attacks—which can be life-threatening—frequently occur at night.
What should I know about COVID-19 and asthma?
If you have moderate to severe asthma or if your symptoms are not well-controlled, you are at a higher risk of requiring hospitalization if you contract COVID-19. Therefore, please wear a mask in indoor public spaces, stay up to date with your vaccinations, and maintain distance from individuals who are ill.
Many people with asthma lead fulfilling, active lives—some even become elite professional athletes. Your doctor can help you find the best way to manage your condition. Please have an open conversation with your healthcare provider about how to effectively maintain control of your symptoms.
