If you are searching for asthma treatment, there is a good chance you are already living with some version of the same problem: a cough that wakes you at night, a chest that tightens on the stairs, or a reliever inhaler you reach for more often than you would like to admit. For many people in the Delhi-NCR region, symptoms also seem to worsen during winter, festival season or on high-pollution days.

The encouraging part is that asthma is a condition that can usually be controlled. This guide explains how asthma is recognised, how doctors judge whether it is controlled, what the different medicines do, and when it is time to look at more advanced options.

What is asthma?

Asthma is a long-term condition in which the airways, the tubes that carry air in and out of your lungs, become inflamed and unusually sensitive. When they react to a trigger, the airway lining swells, the muscles around the airways tighten and extra mucus is produced. Air then moves through a narrower passage, which causes wheezing, breathlessness and cough.

Two features separate asthma from many other lung conditions. First, symptoms vary: you can feel well for days and then struggle for a few hours. Second, the narrowing is usually reversible, either on its own or with treatment. Asthma can begin in childhood, but it can also start for the first time in adulthood.

Asthma symptoms and warning signs

The common asthma symptoms are:

• Wheezing, a whistling or squeaky sound when breathing out
• Cough, often worse at night, early morning or after exercise
• Chest tightness or heaviness
• Shortness of breath that comes and goes

Not everyone has all four. Some adults have only a long-lasting cough, which is sometimes called cough-variant asthma.

Warning signs that need urgent medical attention include difficulty speaking in full sentences, a reliever inhaler that gives little or no relief, blue or grey lips, drowsiness or confusion, and breathing that is getting faster or more laboured. Do not wait for an appointment if these appear.

Controlled and uncontrolled asthma: what is the difference?

This is one of the most useful ideas in asthma care, because the aim of treatment is not simply “fewer attacks”. It is good day-to-day control.

A simple way to check, based on the questions used in international asthma guidance, is to think about the last four weeks:

1. Did you have daytime asthma symptoms more than twice a week?
2. Did asthma wake you at night?
3. Did you need your reliever inhaler more than twice a week?
4. Did asthma limit your usual activities?

If the answer to all four is no, asthma is likely well controlled. If you answered yes to one or more, your asthma may be partly controlled or uncontrolled, and your treatment probably needs a review.

Uncontrolled asthma matters even if your symptoms feel “manageable”. Persistent inflammation increases the risk of a severe attack, repeated steroid courses, missed work or school, and in some people long-term changes in the airways. Many patients tolerate poor control for years because they have forgotten what normal breathing feels like.

Causes, risk factors and common asthma triggers

The exact cause of asthma is not fully understood. It usually results from a combination of inherited tendency and environmental exposure. Established risk factors include:

• A personal or family history of asthma, eczema, hay fever or other allergies
• Exposure to tobacco smoke, including second-hand smoke
• Occupational exposure to dusts, fumes, chemicals or isocyanates
• Obesity
• Early-life respiratory infections in some children

It is also useful to separate risk factors (why you developed asthma) from triggers (what sets off symptoms). Common triggers include:

• Viral infections such as the common cold and flu
• House dust mites, pollen, mould, pets and cockroach allergens
• Smoke, strong fragrances, incense and cooking fumes
• Air pollution and sudden changes in temperature
• Exercise, particularly in cold or dry air
• Reflux (GERD), stress and strong emotions
• Certain medicines in sensitive people, such as aspirin or other pain relievers in the NSAID group, and beta-blockers

Keeping a short diary of when symptoms appear can help your doctor identify patterns that are easy to miss.

How is asthma diagnosed?

There is no single test that diagnoses asthma in every patient. Doctors combine your symptom pattern, examination findings and objective tests.

Detailed history and examination. Questions about timing, triggers, allergies, family history, occupation, home environment and medicines are often as important as any test.

Spirometry (pulmonary function testing). Spirometry is the key test. You breathe into a device that measures how much air you can blow out and how fast. In asthma it typically shows airflow obstruction that improves after a bronchodilator (reliever) is given. A normal result does not exclude asthma, because airways can be normal between episodes, so the test may need to be repeated.

Peak expiratory flow monitoring. Measuring peak flow at home over a couple of weeks can show the day-to-day variation that is characteristic of asthma.

Other tests when appropriate:

• FeNO (fractional exhaled nitric oxide) to assess airway inflammation, where available
• Blood eosinophil count and total IgE to identify an allergic or eosinophilic pattern, which matters especially in severe asthma
• Allergy testing to find specific triggers
• Chest X-ray or HRCT when the picture is unclear or another condition is suspected

The diagnosis also needs to be separated from other causes of wheeze and cough, including COPD, heart-related breathlessness, vocal cord problems, reflux and post-infectious cough. This is one reason a specialist assessment helps when the diagnosis is not straightforward.

How asthma is controlled and treated

The goals of asthma management are to keep symptoms minimal, prevent attacks, maintain normal activity, protect lung function and use the lowest effective amount of medicine. Treatment is adjusted in steps, going up when control is poor and down when it has been stable for some time.

Lifestyle and supportive measures

Medicines work best when avoidable triggers are reduced. Practical steps include:

• Stopping smoking and avoiding smoke exposure at home
• Reducing dust-mite exposure: washing bedding in hot water, using mattress and pillow covers, and avoiding heavy carpeting where possible
• Checking the air quality index and limiting outdoor exertion on poor-air days, and considering a well-fitted mask on such days if your doctor advises it
• Managing reflux and nasal allergy, which can worsen asthma
• Maintaining a healthy weight and staying physically active
• Getting vaccinations your doctor recommends, such as influenza and pneumococcal vaccines

Controller versus reliever medicines

Patients often mix these up, so it is worth being clear.

Reliever medicines open the airways quickly for symptoms. They are used when needed and do not treat the underlying inflammation. Traditional relievers are short-acting beta-agonists. Current international guidance also supports a reliever that combines a low-dose inhaled steroid with a fast-acting long-acting bronchodilator (formoterol) for suitable patients.

Controller medicines treat the underlying inflammation and are taken regularly, or in some regimens as directed by your doctor, even when you feel well. The foundation of controller treatment is the inhaled corticosteroid (ICS). Many people use a combination inhaler that contains an ICS plus a long-acting bronchodilator (LABA).

One point from current guidance deserves emphasis: relying on a reliever inhaler alone, without any anti-inflammatory treatment, is no longer recommended for most adults with asthma. If you use a blue reliever frequently and have never been advised about a controller, ask your doctor to review your regimen.

The role of inhalers

Inhalers deliver medicine directly to the airways, so a much smaller dose is needed than with tablets, and side effects are fewer. But inhalers only work if they are used correctly. Common problems include not breathing in at the right moment, not using a spacer when one is advised, not rinsing the mouth after an inhaled steroid and stopping the controller as soon as symptoms settle.

Different devices suit different people: pressurised metered-dose inhalers (with or without a spacer), dry-powder inhalers and soft-mist inhalers. Your technique should be checked at the clinic, not just described to you, and re-checked periodically.

Other medicines

Depending on your asthma pattern, your doctor may add:

• Leukotriene receptor antagonists, taken as tablets, which can help especially where allergy or exercise is a trigger
• Long-acting anticholinergic (LAMA) inhalers as add-on treatment
• Allergy treatment, including antihistamines or nasal sprays for associated rhinitis
• Short courses of oral corticosteroids for acute worsening, which should be limited because repeated or long-term use can cause side effects
• Allergen immunotherapy in carefully selected allergic patients

Doses and combinations are always individual and should be decided by your treating doctor.

Oxygen therapy and pulmonary rehabilitation

Oxygen is not part of routine asthma treatment. It is given in hospital during a severe attack or when oxygen levels are low. Pulmonary rehabilitation is used less often for asthma than for COPD, but breathing retraining and supervised exercise can help people who have persistent breathlessness, poor fitness or breathing-pattern problems alongside asthma.

Severe asthma and advanced therapies

Severe asthma is not simply asthma that feels bad. It refers to asthma that stays uncontrolled despite high-dose inhaled treatment with good adherence and technique, or that can only be controlled by continuing high-dose treatment, sometimes with regular oral steroids.

Before asthma is labelled severe, a specialist usually checks for the common reasons for apparent poor control:

• Inhaler technique or adherence problems
• A wrong or additional diagnosis
• Ongoing exposure to triggers, including smoking and workplace allergens
• Coexisting conditions such as chronic sinus disease, reflux, obesity or sleep problems

If asthma is still uncontrolled after these are addressed, the next step is to identify its type, for example allergic or eosinophilic, using blood tests and other assessment. This opens the door to biologic therapies, injectable medicines that target specific immune pathways involved in asthma. Depending on the type, options include anti-IgE, anti-IL-5, anti-IL-4 receptor and anti-TSLP treatments. In a few carefully selected patients, a procedure such as bronchial thermoplasty may be discussed, although its role is limited and availability varies.

Advanced therapies are not for everyone and have specific eligibility criteria, cost considerations and monitoring needs. They should be started only after a full specialist assessment.

Follow-up and monitoring

Asthma is monitored, not just treated. Review visits usually look at symptom control, reliever use, exacerbations, inhaler technique, side effects and periodic spirometry. Many patients benefit from a written asthma action plan, which tells you what to do when symptoms worsen, which medicines to increase, and when to seek help.

When hospitalisation may be necessary

Hospital care may be needed if there is severe breathlessness not relieved by a reliever, difficulty speaking, low oxygen levels, exhaustion, or a very low peak flow reading. Some patients need oxygen, nebulised medicines, injected or intravenous steroids and close monitoring, and a few need intensive care.

When should you see a pulmonologist?

Consider a specialist evaluation if:

• Cough, wheeze or breathlessness has lasted more than a few weeks or keeps returning
• You use a reliever inhaler more than twice a week
• Asthma wakes you at night or limits your activity
• You have needed steroid tablets or emergency care more than once in a year
• You are not sure your diagnosis is correct
• You are on regular inhalers but still symptomatic
• Asthma started in adulthood or you also have nasal polyps, sinus disease or aspirin sensitivity
• You are pregnant or planning pregnancy with asthma

Asthma care in Gurgaon and Delhi/Dwarka

If you are looking for an asthma specialist in Gurgaon or an asthma specialist in Delhi, a few practical points can help you choose a service that suits you.

• Qualifications and focus: Look for formal training in pulmonary or respiratory medicine and regular experience in managing airway disease.
• Access to testing: Asthma assessment is much more reliable when spirometry and, if needed, FeNO, allergy testing and imaging are available in one place.
• Time for inhaler teaching: Ask whether your technique is checked and whether you will get a written action plan.
• Continuity and emergency support: Asthma can flare quickly, so hospital-based care with emergency backup is useful.
• Convenience: For a long-term condition, a location you can actually reach for regular reviews matters.

Dr. Shivanshu Raj Goyal is Director & Unit Head – Pulmonology, Respiratory & Sleep Medicine at Max Healthcare, Gurgaon & Dwarka, Delhi. Patients who prefer to be seen in Gurugram can read about consultation at the pulmonologist in Gurgaon page, while those in West Delhi can see the details for a pulmonologist in Dwarka.

Before your appointment, bring your previous prescriptions or inhalers, any spirometry or chest imaging reports, and a note of when symptoms occur. This can save time and lead to a more focused discussion.

Why personalised treatment matters

Two people can both be told they have asthma and need very different plans. One may have mild, allergy-driven symptoms in the pollen season, while another has year-round eosinophilic asthma with nasal polyps. A third may have asthma that is mostly triggered by workplace exposure, or asthma complicated by reflux and sleep apnea, which can worsen night-time breathing and daytime fatigue.

Severity, age, pregnancy, other illnesses, inhaler preference, previous attacks, test results and personal goals all shape the plan. This is why copying someone else’s inhaler or stopping yours because a relative “does not use any” can be risky.

Long-term management and prevention

Asthma cannot always be prevented, but attacks usually can be. Evidence-based practical advice includes:

• Take controller medicines as prescribed, even when you feel well, unless your doctor has given a different plan
• Carry your reliever and know your action plan
• Avoid smoking and tobacco smoke
• Reduce known triggers, especially during high-pollution periods
• Treat nasal allergy and reflux
• Stay active, within your doctor’s guidance
• Get recommended vaccinations
• Do not rely on a reliever alone if it is needed often
• Have your asthma reviewed regularly, at least once a year even when stable

Frequently asked questions

What is the most effective treatment for asthma?

There is no single most effective treatment for everyone. For most people, regular or as-directed anti-inflammatory treatment with an inhaled corticosteroid, combined with a suitable reliever and trigger control, gives the best control. The right plan depends on your asthma type and severity.

Can asthma be completely cured?

Asthma is generally considered a long-term condition that can be controlled rather than permanently cured. Some children outgrow symptoms, and some adults achieve long periods without symptoms on treatment, but the tendency can return.

What tests are needed to diagnose asthma?

Usually a detailed history, examination and spirometry with a bronchodilator response test. Peak flow monitoring, FeNO, blood eosinophils, IgE, allergy testing and imaging may be added depending on the situation.

When should I see a pulmonologist for asthma?

See one if symptoms persist, if you need your reliever more than twice a week, if you have had steroid courses or emergency visits, if the diagnosis is uncertain, or if asthma is not controlled on regular inhalers.

Can asthma get worse without treatment?

Yes. Untreated or poorly controlled asthma increases the risk of severe attacks and hospital admission and, in some people, can lead to long-term airway changes.

How long does asthma treatment take?

Most people need treatment for a long period, with the dose stepped up or down as control changes. Symptom improvement can begin within days to weeks, but the aim is long-term control and regular review.

Can lifestyle changes help asthma?

Yes. Avoiding smoke, reducing allergen and pollution exposure, treating reflux and nasal allergy, staying active and maintaining a healthy weight can all reduce symptoms. They support, but do not replace, prescribed inhalers.

What medicines are commonly used for asthma?

Commonly used medicines include inhaled corticosteroids, combination inhalers with a long-acting bronchodilator, reliever inhalers, leukotriene receptor antagonists and sometimes add-on inhalers or biologic injections. Which ones suit you is a decision for your doctor.

When is hospitalisation required for asthma?

Hospital care is needed for severe attacks: marked breathlessness, difficulty speaking, poor response to a reliever, low oxygen levels or exhaustion.

Can asthma recur?

Symptoms can return, particularly with infections, allergen or pollution exposure, missed controller treatment or other triggers. Regular follow-up helps spot early warning signs.

Are asthma inhalers addictive or harmful if used for years?

No. Inhalers deliver small doses directly to the airways and are considered safe for long-term use when used as prescribed. Using them correctly is more important than worrying about dependency.
