Asthma: Types, Causes, Symptoms, Diagnosis & Treatment

What is Asthma?

Asthma is a chronic disease that affects your lungs' airways. People with asthma find it hard to breathe because their airways become inflamed and narrow, making it difficult to exhale air. People with asthma experience wheezing, coughing (especially at night or during exercise), chest tightness, and shortness of breath.

Types of Asthma

Doctors classify asthma into four main categories based on how severe & frequent the symptoms are:

Intermittent asthma: Symptoms show up no more than twice weekly, and breathing returns to normal between episodes.

Mild persistent asthma: People experience symptoms more than twice weekly but not daily, with slight activity limitations.

Moderate persistent asthma: You may experience symptoms of asthma daily, limiting your daily activities. It causes lower breathing test scores.

Severe persistent asthma: You may have symptoms throughout the day. Because of these symptoms, you are not able to carry out your daily tasks and need your rescue inhaler frequently.

Doctors have identified few more types of asthma which include: 

• Allergic

• Exercise-induced

• Occupational

• Nighttime asthma

Causes & Triggers for Asthma

Scientists haven't pinpointed the exact causes, which likely vary among individuals. Several factors boost your risk:

• Family history (especially maternal)

• Allergies and allergic conditions

• Obesity

• Race or ethnicity (higher risks for Black and Puerto Rican people)

• Occupational hazards

Triggers can include:

• Indoor and outdoor allergens

• Emotional stress

• Physical activity

• Infections

• Certain medications

• Poor air quality

• Cold air

Common Symptoms of Asthma

People with asthma experience:

• Wheezing (whistling sound during exhale)

• Coughing, especially at night or early morning

• Shortness of breath

• Chest tightness or pain

These symptoms often follow specific patterns—they come and go, worsen with infections, or appear with certain triggers.

Asthma Diagnosis

Doctors typically diagnose asthma through:

• Medical history and physical examination: Doctors examine breathing sounds and go over symptoms and possible triggers

• Lung function tests: These include spirometry and peak flow measurements to check the amount and speed of air you breathe in or out.

• Challenge tests:  They check how sensitive airways are when exposed to things like exercise or specific medicines.

• Allergy testing: These tests help to find out if allergens like dust, pollen, or pets are causing asthma issues.

• Nitric oxide breath test: This checks inflammation in the airways by measuring nitric oxide levels in your exhaled breath.

Treatment Options for Asthma

Doctors recommend various treatments:

• Quick-relief medicines to ease asthma symptoms. They will relax your airway muscles when there is an episode of a sudden attack of asthma.

• Controller medicines lower swelling in your airways and prevent regular symptoms related to asthma.

• Biologic medications in the form of injections target certain immune responses. 

• Allergy treatments manage allergic triggers with medication or immunotherapy.

Your treatment plan depends on how severe your asthma is, ranging from occasional rescue inhalers to daily controller medications.

Conclusion 

Life with asthma has its challenges, but most people lead full, active lives with proper management. Your specific type of asthma whether it is intermittent, mild, moderate, or severe determines the treatment plan that your doctor will curate for you.

Getting diagnosed early makes a vital difference if you experience wheezing, coughing, or shortness of breath. Your doctor might suggest lung function tests or allergy assessments to confirm your condition and check its severity. Treatment usually combines quick-relief medications to control immediate symptoms and long-term medicines to prevent attacks.

As an asthmatic patient, you need to know your triggers. It can be anything (weather changes, pollen, stress, exercise, or workplace irritants). If you have a plan against your triggers half of the battle against this condition is won. 

Asthma doesn't have to hold you back from your dreams or activities. Athletes, musicians, actors, and people from every background succeed despite having asthma. Success comes from staying aware, using medications properly, and keeping regular appointments with doctors. You can make asthma just another part of your life rather than something which defines who you are.
