Asthma: Symptoms, Diagnosis and Treatment

Overview

Asthma is a chronic respiratory condition in which the airways become inflamed, narrowed, and produce excess mucus, making it difficult to breathe. It affects about 25 million people in the United States, including about 7 million children. The severity ranges from mild, occasional symptoms to severe, life-threatening attacks.

Asthma is characterized by episodes of wheezing, shortness of breath, chest tightness, and coughing, which are triggered by various factors including allergens (pollen, dust mites, pet dander), irritants (smoke, air pollution, strong odors), exercise, cold air, respiratory infections, and stress. These triggers cause the airways to constrict (bronchospasm), swell, and produce mucus.

Asthma is a chronic condition — even when you feel fine, the inflammation is present. This is why daily controller medications are essential for most people with persistent asthma, not just rescue inhalers for attacks. With proper treatment, most people with asthma can lead full, active lives. Uncontrolled asthma can be life-threatening, so understanding and following your treatment plan is critical.

Symptoms

Wheezing — a whistling sound when breathing
Shortness of breath
Chest tightness or pressure
Coughing, especially at night, early morning, or with exercise
Symptoms triggered by allergens, exercise, cold air, or infections
Attacks that vary in severity and frequency
Waking at night with coughing or breathing difficulty
Difficulty speaking during severe attacks

Diagnosis

Spirometry — measures how much air you can exhale and how fast; the key diagnostic test
Peak flow monitoring — measures maximum exhale speed; used for ongoing monitoring
Bronchodilator response test — improvement in lung function after using an inhaler confirms asthma
Methacholine challenge — for cases where spirometry is normal but asthma is suspected
Allergy testing — skin or blood tests to identify triggers
Exhaled nitric oxide (FeNO) — measures airway inflammation
Chest X-ray — to rule out other conditions

A pulmonologist or primary care physician makes the diagnosis.

Treatments

Quick-relief (rescue) medications — short-acting beta-agonists (albuterol); relax airway muscles during attacks
Controller medications — inhaled corticosteroids (fluticasone, budesonide); reduce inflammation; taken daily
Long-acting beta-agonists (LABAs) — combined with inhaled steroids for moderate to severe asthma
Leukotriene modifiers — montelukast; oral medication for daily control
Biologic agents — omalizumab, mepolizumab, benralizumab, dupilumab; for severe asthma
Oral corticosteroids — for severe flares; short-term use
Allergy management — allergy shots (immunotherapy), avoiding triggers
Asthma action plan — a written plan for managing symptoms and attacks
Lifestyle — avoiding triggers, regular exercise, not smoking, managing stress
Regular monitoring — peak flow monitoring, spirometry, annual check-ups

Your Care Plan

A step-by-step guide to navigating your condition, from finding the right doctors to advocating for the care you deserve.

Step 1: Doctors to See

Start with: Your primary care physician for initial evaluation and spirometry.

Then seek: A pulmonologist if asthma is severe, difficult to control, or if diagnosis is unclear.

Build your team:

Primary care physician or pulmonologist — for asthma management
Allergist — for allergy testing and immunotherapy
Respiratory therapist — for inhaler technique and education
Emergency care — for severe attacks

Step 2: Advocate for Yourself

If you're using your rescue inhaler more than twice a week, your asthma isn't well-controlled — ask about a controller medication. If your symptoms persist despite treatment, ask about biologics for severe asthma. If you're waking at night with symptoms, your asthma needs better control — don't accept it as normal. Get an asthma action plan in writing so you know exactly what to do when symptoms worsen. If you have allergies, ask about immunotherapy — treating allergies can improve asthma.

Step 3: Your Action Plan

See your primary doctor if you have wheezing, cough, or shortness of breath.
Get spirometry to confirm asthma.
Identify and reduce your triggers.
Start controller medication as prescribed — daily use is critical.
Get an asthma action plan from your doctor.
Monitor your peak flow or symptoms regularly.
Get annual flu shots and discuss pneumonia vaccination.
Seek emergency care for severe attacks — don't wait.
