Breathing is something most of us never think about until it becomes difficult. If you have been dealing with a persistent cough, recurring chest infections, or breathlessness that just won’t quit, it may be time to stop attributing it to seasonal changes or stress. A pulmonologist can get to the root of what’s going on.
A pulmonologist is a specialist in diagnosing and treating conditions that affect the lungs and the entire respiratory system. This includes everything from the airways and lung tissue to the blood vessels within the lungs and the muscles that support breathing.
Conditions commonly managed by a pulmonologist include:
If your symptoms involve the chest or your ability to breathe comfortably, a pulmonologist is the right specialist to see.
Almost everyone coughs occasionally. But a cough that lingers for more than three weeks is classified as chronic, and it deserves proper evaluation.
Most people brush off a long-standing cough as post-cold residue or a throat irritation. In many cases, though, a chronic cough is a signal of something deeper, such as:
Pay particular attention if your cough is accompanied by blood, significant mucus production, unexplained weight loss, or night sweats. These are signs that warrant urgent evaluation.
Feeling short of breath after a hard workout is expected. Feeling short of breath while climbing a single flight of stairs, talking for a few minutes, or getting dressed in the morning is not.
Breathlessness that interferes with daily activity, known medically as dyspnoea, is one of the clearest indicators that something is affecting your lung function. Similarly, wheezing (that audible, high-pitched sound when you breathe) points toward airway narrowing that needs investigation.
You should see a pulmonologist if:
Do not dismiss these symptoms as ageing or being unfit. They are your lungs communicating that something is off.
Getting a chest infection once is common enough. Getting them repeatedly (two or more times in a year) is a pattern that needs investigation. Recurrent chest infections or pneumonia suggest that your airways or immune defences may be compromised in some way. Possible underlying causes include:
Each infection that goes uninvestigated at the root level can cause incremental lung damage. A pulmonologist will assess whether there is a structural, functional, or immunological reason for the recurrence and create a plan to break the cycle.
Asthma and COPD are two of the most prevalent chronic respiratory conditions worldwide, and both are frequently under-diagnosed or mismanaged. Allergic conditions, including allergic rhinitis and hypersensitivity pneumonitis, also fall within a pulmonologist’s scope of care.
Asthma is not just a childhood condition. Adult-onset asthma is common and can be triggered by occupational exposures, hormonal changes, or stress. If you find yourself relying on a reliever inhaler more than twice a week, your asthma is not well-controlled and needs reassessment.
COPD typically develops in smokers or those with long-term exposure to pollutants or fumes. It is progressive, meaning it gets worse over time, but proper management significantly slows that progression. Early diagnosis is key.
Allergy-related breathing issues often get masked as seasonal problems. A pulmonologist can determine whether your symptoms point to true asthma, allergic bronchopulmonary aspergillosis, or another condition entirely.
In a city like Bangalore, where traffic pollution and construction dust are constant, respiratory conditions are increasingly common. Consulting a pulmonologist in Bangalore sooner rather than later can make a real difference in long-term lung health.
The quality of your breathing during sleep has a direct impact on your heart health, brain function, metabolism, and overall quality of life. Yet sleep-related breathing disorders are among the most underdiagnosed conditions in general medicine.
Consider seeing a pulmonologist if you or someone close to you notices:
These symptoms are characteristic of obstructive sleep apnoea (OSA), a condition where the airway partially or fully collapses during sleep. Left unmanaged, OSA is associated with a significantly elevated risk of hypertension, heart disease, and stroke. A pulmonologist can arrange a sleep study and recommend appropriate management, which may include lifestyle changes, positional therapy, or CPAP therapy.
A general physician is your first point of contact for most health concerns, and for straightforward respiratory infections like a common cold or mild flu, that is often sufficient. But there is a meaningful difference between the two consultations when it comes to complex or persistent lung conditions.
| General Physician | Pulmonologist | |
| Scope | Broad, across all organ systems | Specialised in lungs and respiratory tract |
| Training | MBBS + general medicine | Additional 3-year DM/DNB in pulmonology |
| Investigations | Basic blood work, X-ray | Pulmonary function tests, bronchoscopy, sleep studies |
| Ideal for | First consultations, mild infections | Chronic, complex, or unresolved respiratory conditions |
If your GP has treated you for the same respiratory complaint more than twice without resolution, a referral to a pulmonologist is the appropriate next step. Knowing when should you see a pulmonologist rather than continuing with general management can spare you months of ineffective treatment.
Depending on your symptoms, history, and initial examination, a pulmonologist may use one or more of the following investigations to reach a diagnosis:
Measures how much air you can inhale and exhale and how quickly. Essential for diagnosing and staging asthma and COPD.
Provides detailed imaging of lung tissue, airways, and surrounding structures. HRCT is particularly useful for detecting interstitial lung diseases and pulmonary fibrosis.
A thin, flexible camera is passed into the airways to directly visualise the bronchi, collect samples, or clear obstructions.
Measures oxygen and carbon dioxide levels in the blood, giving a direct picture of how well the lungs are functioning.
Fractional exhaled nitric oxide testing helps assess airway inflammation, particularly in asthma.
An overnight test that monitors breathing, oxygen levels, brain activity, and movement to diagnose sleep-related disorders.
Analyses mucus coughed up from the lungs to identify infection-causing organisms and guide antibiotic selection.
You do not need to wait until a symptom becomes unbearable to seek specialist input. Early consultation leads to earlier diagnosis, less aggressive treatment, and better outcomes.

1. What does a pulmonologist do?
A pulmonologist diagnoses and treats conditions affecting the lungs and respiratory system. They conduct lung function tests, interpret imaging, perform procedures like bronchoscopy, and manage both acute and chronic respiratory conditions.
2. What are pulmonology diseases?
Common pulmonology conditions include asthma, COPD, pulmonary fibrosis, pneumonia, tuberculosis, bronchiectasis, pulmonary hypertension, interstitial lung disease, and obstructive sleep apnoea.
3. What problems can a pulmonologist treat?
Chronic cough, breathlessness, wheezing, recurrent chest infections, persistent mucus production, low oxygen levels, and sleep-related breathing problems all fall within a pulmonologist’s scope of care.
4. Are pulmonologists MBBS doctors?
Yes. Pulmonologists complete an MBBS, followed by an MD, and then a DM or DNB in pulmonary medicine, making them specialists with over a decade of medical training.
5. How do I know if my breathlessness is cardiac or pulmonary in origin?
Both can present similarly and may even coexist. A pulmonologist will evaluate your symptoms and coordinate with a cardiologist if needed.
