Asthma in Adults: A Practical Guide to Living Well

Asthma affects over 30 million people in India. While it is a chronic condition with no cure, it is one of the most controllable chronic diseases in medicine. The global target set by GINA (Global Initiative for Asthma) is for every asthma patient to achieve good symptom control with minimal side effects — meaning no daytime symptoms, no nocturnal wakening, and full participation in normal activities including exercise. Many patients accept far less than this. They don't have to.

Understanding Your Airways

Asthma involves two processes working together — and both need to be addressed. First, airway inflammation: the lining of the bronchial tubes is persistently inflamed and hypersensitive, even when symptoms are absent. Second, bronchoconstriction: the smooth muscle surrounding the airway constricts in response to triggers, narrowing the lumen and causing the characteristic wheeze, breathlessness and coughing.

Identifying Your Triggers

Triggers vary significantly from patient to patient. Common ones include:

• Allergens — house dust mites, cockroach, pet dander, mould spores, pollen
• Respiratory infections — viral upper respiratory infections are the most common trigger for acute attacks
• Exercise — especially in cold or dry air; does not mean you should avoid exercise
• Occupational exposure — chemical fumes, flour dust, latex, wood dust
• Air pollution — particulate matter (PM2.5) from traffic, construction, fires
• Tobacco smoke — both active and passive
• Strong emotional stress
• Aspirin and NSAIDs — in susceptible patients with aspirin-exacerbated respiratory disease (AERD)
• GERD (acid reflux) — aspiration of acid micro-droplets inflames airways; often nocturnal

Preventer vs Reliever Inhalers

Understanding the role of each inhaler is fundamental:

• Preventer (controller) inhalers — contain inhaled corticosteroids (ICS) such as budesonide or fluticasone. These reduce airway inflammation and must be taken DAILY even when you feel well. They work over weeks to months.
• Reliever inhalers — contain short-acting bronchodilators (SABA: salbutamol/albuterol). They provide rapid relief within minutes during a flare. Overuse (>2 days/week) signals poorly controlled asthma
• Combination inhalers — ICS + long-acting bronchodilator (LABA). Standard of care for moderate-severe asthma. Examples: budesonide/formoterol, fluticasone/salmeterol
• Anti-leukotrienes — montelukast tablets often used as add-on therapy, especially when rhinitis and asthma coexist

Your Asthma Action Plan

Every asthma patient should have a written action plan prepared with their doctor. It is divided into three zones based on your peak flow or symptom score:

• Green zone (controlled) — take preventer as usual; continue normal activities
• Yellow zone (caution) — increase reliever as directed; consider temporary increase in preventer doses per plan
• Red zone (medical emergency) — take reliever immediately; call your doctor or go to emergency; do not delay

When to Seek Urgent Care

Go to the emergency department immediately if you experience: inability to speak in full sentences, severe breathlessness at rest, lips or fingertips turning blue, reliever inhaler providing no relief, or symptoms that are rapidly worsening. Never underestimate a severe asthma attack.

Asthma managed proactively — with the right preventer, correct inhaler technique, trigger identification, and a written action plan — should not define or limit your life. If your symptoms are more frequent than twice a week, or if you are waking at night, or if you have had an emergency visit in the past year, book a review. Your treatment can almost certainly be improved.
