The chronic disease known as asthma affects the bronchial tubes, which are the passageways through which air enters and exits the lungs. It causes inflammation and narrowing of these airways. The lung’s airways shrink as a result, and the muscles surrounding the tiny airways tighten, limiting the amount of air that may enter the body. Breathing difficulties may result from this, and you may cough, wheeze, or produce a whistling sound when you exhale or feel short of breath.

Asthma Bhawan offers a comprehensive guide designed to help individuals understand Asthma better. This simple overview describes the symptoms, causes, and effects of asthma on the respiratory system. Covering symptoms including coughing, wheezing, and shortness of breath, it offers important information on how to manage the illness with medication, lifestyle modifications, and preventative treatment. The guide also emphasizes the importance of recognizing triggers and maintaining a healthy environment to reduce Asthma flare-ups. 

Causes and Triggers

Environmental and genetic factors combine to produce breathing problems. Asthma symptoms can be exacerbated or triggered by specific situations and surroundings. Some of the possible causes and triggers include:

• Respiratory infections like colds, sinusitis, pneumonia, and flu.
• Allergens such as mold, pollen, animal dander, and dust mites.
• Airborne irritants include smoke, strong odors (cleaning products, perfumes), and chemical vapors.
• Exercises or extra activity around the body could make breathing harder.
• Changes in weather such as extremes in temperatures, or humidity.

Risk Factors

The following factors could increase your chance of getting asthma or exacerbate its symptoms:

• Family History and Genes: A child is more likely to get asthma if they have an asthmatic parent, especially the mother.
• Ethnicity: Another factor that may increase your risk of developing asthma is your ethnicity. For instance, those of Puerto Rican or African American heritage are more susceptible to asthma.
• Smoke: Exposure to smoke in the womb or during early childhood.
• Occupational Hazards: Asthma risk is also increased by jobs involving chemical irritants or industrial dust, a condition known as occupational asthma.
• Various medical issues, including obesity, allergies, and lung infections.
• Exposure to poor air quality due to pollution or allergens.

Signs and Symptoms

People with asthma may experience symptoms such as:

• Shortness of breath.
• Whistling or wheezing sound when you breathe and exhale.
• Pain or chest tightness and pressure in the chest.
• Breathing problems that interfere with sleep.
• Coughing, especially during early in the morning or the night.

However, not every person with asthma experiences the same symptoms in the same way.

The severity or intensity of your asthma and whether or not you are exposed to allergens determine how frequently you experience the signs and symptoms of asthma.

For example, symptoms may be present daily for some persons and infrequently for others. Moreover, when asthma is well under control, a person may show fewer symptoms. 

1. Diagnosis 

A physical examination and questions about your symptoms and medical history will be the first steps taken by a pulmonologist, an expert in allergies and immunology. To find out if you have asthma or not, you can take the following tests:

• Spirometry Tests measure how fast and how fast you blow out air.
• Bronchoprovocation Tests quantify the response of your airways to particular exposures. You will breathe various doses of allergens or medications throughout this test, which could tighten the muscles in your airways.
• Peak Expiratory Flow (PEF) tests evaluate how quickly you can exhale when exerting your greatest effort. This test can be done during spirometry or by breathing into a separate device such as a tube.
• The fractional exhaled nitric oxide (FeNO) test quantifies the amount of nitric oxide in your exhaled breath. A high nitric oxide level could indicate inflammation in your lungs.
• Allergy skin or blood tests can tell your doctor which allergens cause a reaction in your immune system.

2. Treatment 

There is no cure for asthma, but there are therapies that can help manage its symptoms. People with asthma can live normal lives by using inhaled drugs to control the illness. Two main types of inhalers include:

• Bronchodilators such as salbutamol, clear the airways and lessen the symptoms of asthma.
• Steroids like beclomethasone improve asthma symptoms by reducing airway inflammation.

3. Prevention 

The following techniques can aid in preventing asthma attacks or worsening of asthma:

• Asthma Action Plan: Asthma is a chronic illness that requires constant care and observation. To manage an asthma attack, follow your doctor’s prescribed asthma action plan and medications. 
• Avoid Triggers: Recognize the causes that have previously made your asthma attacks worse and avoid them.
• Monitor Breathing: Use a home peak flow meter to periodically check your breathing because lung function may deteriorate before you notice the symptoms.
• Respond to Alerts Quickly: As directed by your doctor, take your prescription and cease any activities that might have caused the attack. 
• Take Prescribed Medications: Observe your physician’s advice when taking your asthma prescriptions. Never switch drugs without first talking to your doctor. 
• Take Notice of Inhaler Use: If you observe that you are using a quick-relief inhaler more frequently, consult your physician.
• Taking Preventive Medication: You can be prescribed medication by your doctor to take on a daily basis. In an emergency, you may take this medication in addition to your usual prescription. 
• Reduce Tobacco Exposure: Asthma management and primary prevention both depend on lowering your exposure to tobacco smoke.

FAQs

What is Asthma?

Breathing difficulties, coughing, wheezing, and shortness of breath are symptoms of asthma, a chronic respiratory disease that causes inflammation and airway narrowing.

What are common triggers for asthma?

Allergens (pet dander, dust mites, pollen), environmental contaminants, respiratory diseases, intense emotions, physical exertion, and some medications are common asthma triggers.

What are the symptoms of asthma?

Coughing, wheezing, shortness of breath, chest tightness, and exhaustion are all signs of asthma. These symptoms can vary in severity from mild to severe.

How is Asthma diagnosed?

A patient’s medical history, physical examination, and tests such as spirometry, peak flow monitoring, and allergy testing are all used to diagnose asthma.

What are the treatment options for asthma?

Medications include bronchodilators, corticosteroids, and anti-inflammatory medicines are used to treat asthma. Effective asthma control also requires regular checkups, trigger management, and lifestyle changes.
