Asthma Explained: Causes, Symptoms & Modern Treatment Options

Asthma has a public relations problem. Most people picture a frail child clutching a pump, and conclude it is either rare, or childish, or shameful. None of that is true.

An estimated 34 million Indians live with asthma. And although India has only about an eighth of the world’s asthma patients, it accounts for over 40% of the world’s asthma deaths — largely because the condition is diagnosed late and treated casually.

That gap between “very treatable” and “badly treated” is what this guide is about. It explains what asthma actually is, what triggers it in a city like Hyderabad, how it is properly diagnosed, and what modern treatment looks like — which has changed more in the last few years than in the previous thirty.

What is asthma, in plain language?

Asthma is a long-term condition in which the tubes that carry air into your lungs are inflamed and over-sensitive. Most of the time you feel normal. Then something — dust, smoke, cold air, a viral infection — brushes against those irritable airways, and they overreact.

Three things happen at once during that overreaction: the muscle around the airways squeezes, the lining swells, and the tubes fill with thick mucus. Air now has to move through passages that have narrowed dramatically. That is the wheeze, the tight chest, the cough that will not stop.

The key insight — the one that changes how you treat it — is that the inflammation is there all the time, even on good days. An attack is not the disease. An attack is the flare-up of a fire that was already smouldering.

What are the common symptoms of asthma?

Asthma does not always wheeze. The four classic symptoms are:

• Wheezing — a whistling sound when you breathe out
• Shortness of breath, especially with exertion or at night
• Chest tightness, often described as a band or weight on the chest
• Cough — frequently dry, worse at night or early morning

Two patterns should particularly raise suspicion. A cough that reliably shows up at 2–4 a.m. and disturbs sleep is asthma until proven otherwise. So is a “cold” that goes to the chest every single time and takes three weeks to clear while everyone else recovers in five days.

In some people — especially adults — a chronic dry cough is the only symptom. This is called cough-variant asthma, and it is one of the most commonly missed diagnoses in any chest OPD.

What causes asthma and what triggers an attack?

Nobody fully knows why one person develops asthma and another does not. Genetics load the gun — asthma, eczema and allergic rhinitis run in families as a package doctors call atopy. The environment pulls the trigger.

Triggers vary from person to person, but in Hyderabad the usual suspects are:

• House dust mites — thriving in mattresses, pillows, carpets and curtains
• Air pollution — vehicle exhaust and construction dust, worst in winter smog
• Monsoon mould and damp — fungal spores spike sharply from July to September
• Pollen — particularly in spring and early summer
• Smoke — cigarettes, incense, mosquito coils and kitchen smoke all count
• Viral infections — the single biggest trigger of serious attacks
• Cold air, exercise, strong perfumes and emotional stress
• Certain medicines — aspirin and some painkillers, and beta-blockers

A practical note on our city: many patients at Faith Hospital report their worst months are the monsoon (mould and humidity) and December–January (smog and cold air). If your symptoms follow the calendar, tell your doctor — the pattern itself is diagnostic information.

How is asthma diagnosed?

A good history does half the work: what triggers the symptoms, when they occur, whether allergies or family history are present. But asthma should be confirmed with a breathing test, not guessed at.

The standard test is spirometry. You blow hard into a machine that measures how much air you can force out and how fast. Then you inhale a bronchodilator — a medicine that relaxes the airway muscle — and blow again. If your airflow improves significantly after the medicine, the obstruction is reversible, and that reversibility is the signature of asthma.

Spirometry is painless, takes about 15–20 minutes, and is available at Faith Hospital. Depending on the case, your doctor may add a chest X-ray to rule out other conditions, allergy testing to identify triggers, or a peak-flow diary to track your airways over two weeks.

How is asthma treated today?

Modern asthma treatment rests on one principle: treat the inflammation every day, not just the symptoms on bad days.

Medicines come in two families:

The single most important shift in global guidelines: treating asthma with only a blue rescue inhaler is no longer considered safe. Relying on salbutamol alone relieves the squeeze but leaves the inflammation untouched — and research shows that people who use three or more rescue inhalers a year have a measurably higher risk of severe attacks.

Today, even mild asthma is treated with an anti-inflammatory inhaler, and many patients use a single combination inhaler (ICS-formoterol) as both their daily controller and their reliever. Fewer devices, better protection.

Are inhalers safe? Addressing the fear

This deserves its own section, because inhaler hesitancy causes more uncontrolled asthma in India than the disease’s severity ever could.

Patients regularly tell us they fear inhalers are addictive, or a “last resort,” or that starting one means the asthma has become serious. The biology says the opposite. An inhaler delivers medicine in micrograms — thousandths of a milligram — directly to the airways, which is why it causes far fewer side effects than the same medicine taken as tablets or syrups.

Inhalers are not habit-forming. Needing your controller daily is no more an addiction than needing spectacles daily. And the genuinely risky path is the familiar one: years of cough syrups, antibiotics and oral steroid courses for a condition two puffs a day would have controlled.

One more thing: technique matters enormously. Studies repeatedly show most patients use their inhaler incorrectly, losing much of the dose in the mouth. Have your technique checked at every visit — it takes two minutes and often works better than adding a new medicine.

What about severe asthma?

Roughly 5–10% of patients have asthma that stays uncontrolled despite correct inhaler use. If that is you, two things need to happen.

First, the diagnosis deserves a second look — undiagnosed reflux, sleep apnea, nasal polyps or a wrong diagnosis altogether can all masquerade as “difficult asthma.” Second, genuine severe asthma now has options that simply did not exist a decade ago: biologic injections that target the specific immune pathway driving your inflammation. These are available in India and can transform lives that revolve around emergency visits.

This evaluation is specialist work — it belongs with a pulmonologist, not a pharmacy counter.

What should you do during an asthma attack?

For milder flare-ups: sit upright, stay calm, take your reliever as prescribed — typically repeated puffs over the first hour while watching for improvement. Every asthma patient should have a written action plan from their doctor stating exactly which medicines to step up and when to seek help. If you do not have one, ask at your next visit.

How do you know your asthma is actually controlled?

Most patients grade their asthma on a generous curve. They compare this month to their worst month, conclude things are “manageable,” and quietly absorb symptoms that should not exist. Doctors use a stricter test. Ask yourself about the past four weeks:

• Have I had daytime symptoms more than twice a week?
• Has asthma woken me at night, even once?
• Have I needed my reliever inhaler more than twice a week?
• Have I avoided or limited any activity because of my breathing?

Four answers of “no” means controlled asthma. Even one “yes” means there is room to improve — and worth a review of your medicines, your inhaler technique and your triggers. This matters because treatment is designed to move in steps: stepped up when control slips, and stepped carefully down to the lowest effective dose once you have been stable for a few months. Neither step should happen without your doctor, and the goal is always the same — the minimum medicine that produces a maximum, symptom-free life.

A few habits make control dramatically easier to keep, especially in this city:

• Sun-dry or hot-wash bedsheets and pillow covers weekly — dust mites are Hyderabad’s most reliable indoor trigger
• During monsoon, watch for damp walls and visible mould; a dehumidified, ventilated bedroom earns its keep from July to September
• Check the air quality index in winter; on smog-heavy days, shift outdoor exercise indoors and keep windows closed at peak traffic hours
• Take the annual flu vaccine — viral infections are the most common spark for serious attacks
• Never let the controller inhaler run out; refill at three-quarters empty, not on the last dose
• Keep a dated note of every flare-up — patterns you record are patterns your doctor can prevent

Frequently asked questions

Can asthma be cured permanently?

No — and any clinic promising a permanent cure deserves your scepticism. What modern treatment can do is make asthma functionally invisible: no daytime symptoms, no night waking, no attacks, no limits on exercise. Doctors call this complete control, and most patients can reach it.

Will my child outgrow asthma?

Some children do become symptom-free after adolescence, particularly those with mild, allergy-driven asthma. Others carry it into adulthood, and some adults develop asthma for the first time in their forties or fifties. Treat what is present now rather than waiting to outgrow it.

Can I exercise with asthma?

Yes — and you should. Well-controlled asthma is compatible with any sport, including at the Olympic level. If exercise reliably triggers symptoms, that is a sign your control needs adjusting, not a sign to stop moving.

Is asthma treatment safe during pregnancy?

Yes. Inhaled asthma medicines are considered safe in pregnancy, and the far greater danger to the baby is uncontrolled asthma reducing oxygen supply. Never stop your controller inhaler on your own when you discover you are pregnant — review it with your doctor instead.

Ayurvedic or home remedies — do they work?

Steam, warm fluids and breathing exercises can ease symptoms and are welcome alongside treatment. But nothing herbal reduces airway inflammation the way inhaled corticosteroids do, and every year we admit patients whose attacks became severe while they experimented with alternatives. Use home remedies as company for your inhaler, never as its replacement.

Asthma rewards the patients who take it seriously precisely so it can stop demanding attention. Confirm the diagnosis properly, use a controller inhaler correctly, know your triggers, carry an action plan — and the condition fades into the background of an entirely normal life.

If cough, wheeze or breathlessness keeps returning, consult Dr. Md. Mukarram Ali, Consultant Pulmonologist & Chest Specialist at Faith Hospital, Hyderabad (Yakutpura & Tolichowki). OPD runs Monday to Saturday, 4:00–7:00 PM. Spirometry and a clear diagnosis take one afternoon — most patients wish they had come years earlier.
