A cough that does not go away, repeated wheezing, chest tightness, or shortness of breath during normal activities should not be ignored. A pulmonologist in Kathmandu can help evaluate symptoms related to the lungs, airways, and breathing system. At Nepal National Hospital, Kalanki, pulmonology care is available through the Department of Medicine / Pulmonology, where respiratory symptoms can be assessed with clinical consultation, diagnostic support, and emergency care when needed.
Breathing problems are not always caused by the lungs alone. Sometimes cough and breathlessness may be linked to asthma, COPD, pneumonia, tuberculosis, allergies, post-viral cough, heart disease, anemia, acid reflux, or environmental exposure. That is why a structured medical evaluation is important instead of guessing the cause.
What Does a Pulmonologist Do?
A pulmonologist is a doctor who specializes in diseases of the respiratory system, including the lungs, airways, air sacs, and breathing-related blood vessels. Pulmonologists commonly evaluate symptoms such as chronic cough, wheezing, shortness of breath, chest tightness, repeated chest infections, and long-term phlegm production.
At Nepal National Hospital, pulmonology is listed under the Department of Medicine. The hospital’s official page lists Dr. Prakash Paudyal, MBBS, MD, Pulmonologist, NMC No. 7319, with consultation timing shown as 10 AM–5 PM.
A pulmonologist may help answer questions such as:
- Why am I coughing for so long?
- Is my breathlessness due to asthma, COPD, infection, or another condition?
- Do I need a chest X-ray, PFT, blood test, sputum test, or further imaging?
- Is my inhaler being used correctly?
- Are my symptoms urgent or manageable with outpatient care?
- How can I prevent repeated chest infections or breathing flare-ups?
When Should You See a Pulmonologist for a Cough?
You should consider seeing a pulmonologist when a cough lasts more than a few weeks, keeps coming back, disturbs sleep, causes breathlessness, produces blood, or is associated with fever, weight loss, wheezing, chest pain, or repeated infections.
A cough lasting 8 weeks or longer is generally considered a chronic cough in adults. Chronic cough can affect sleep, energy, daily work, and quality of life, and it needs proper evaluation when it does not improve with basic care.
You should also seek medical evaluation earlier if the cough is severe or comes with warning symptoms. Mayo Clinic advises contacting a healthcare professional if cough continues for a few weeks or is associated with thick greenish-yellow phlegm, wheezing, fever, shortness of breath, fainting, ankle swelling, or weight loss.
Cough Duration: What Is Normal and What Needs Attention?
| Cough Duration | What It May Mean | Suggested Next Step |
|---|---|---|
| Less than 3 weeks | Often linked to viral infection, cold, flu, smoke, dust, or irritation | Monitor symptoms, hydrate, avoid irritants, seek care if symptoms worsen |
| 3–8 weeks | May be post-viral cough, bronchitis, allergy, asthma, reflux, or infection | See a doctor if not improving or if symptoms affect sleep/work |
| 8 weeks or more | Chronic cough; may need lung, airway, allergy, reflux, TB, or medication review | Consult a pulmonologist for structured evaluation |
| 3 weeks or more with TB-like symptoms | Cough with fever, night sweats, weight loss, chest pain, or blood may need TB evaluation | Seek medical care promptly |
A cough lasting 3 weeks or longer, especially with chest pain, blood in sputum, fever, night sweats, or weight loss, may need evaluation for tuberculosis and other serious lung conditions. The CDC lists a bad cough lasting 3 weeks or longer, chest pain, and coughing up blood or sputum as possible symptoms of active TB in the lungs.
When Is Shortness of Breath a Reason to See a Pulmonologist?
Shortness of breath should be checked when it is new, worsening, repeated, or affecting daily life. For example, breathlessness while climbing stairs, walking short distances, lying flat, speaking, or doing routine work may point to an underlying lung or heart-related issue.
A pulmonologist can help assess whether the breathlessness is related to asthma, COPD, chest infection, pneumonia, post-COVID lung changes, interstitial lung disease, occupational exposure, or another respiratory cause.
Shortness of breath with cough becomes more concerning when it is associated with:
- Wheezing or whistling sound while breathing
- Chest tightness or chest pain
- Fever or chills
- Bluish lips or fingers
- Blood in sputum
- Sudden worsening of breathing
- Oxygen level dropping, if measured
- Confusion, fainting, or extreme weakness
In such cases, do not wait for a routine appointment. Visit emergency care immediately.
Three Early Warning Signs of Lung Disease
Many lung diseases begin with symptoms that people ignore as “normal cough” or “seasonal allergy.” The three common early warning signs are:
1. Chronic or Repeated Cough
A cough that lasts for weeks, returns frequently, or does not improve after usual care needs attention. It may be linked to asthma, COPD, infection, allergy, reflux, smoking-related airway disease, or other respiratory conditions.
2. Shortness of Breath During Normal Activities
Breathlessness while walking, climbing stairs, talking, or doing light work is not something to dismiss, especially if it is new or gradually increasing. The CDC lists shortness of breath during everyday activities as a common symptom of COPD.
3. Wheezing, Chest Tightness, or Noisy Breathing
Wheezing may feel like a whistling sound during breathing. It can happen when the airways become narrowed or blocked. The American Lung Association lists wheezing as a warning sign that something unusual may be blocking or narrowing the airways.
Common Conditions a Pulmonologist May Evaluate
Cough and breathing problems can come from many causes. A pulmonologist does not treat every cough the same way. The goal is to identify the pattern, triggers, severity, and underlying condition.
Asthma
Asthma may cause coughing, wheezing, shortness of breath, and chest tightness. Symptoms may be worse at night, early morning, during exercise, after viral infection, or after exposure to dust, smoke, cold air, or allergens. The WHO and NHLBI both describe cough, wheeze, shortness of breath, and chest tightness as common asthma symptoms.
COPD
COPD is a long-term lung disease that can cause airflow limitation. It is often linked with smoking history, indoor smoke exposure, outdoor air pollution, occupational dust, or long-term airway irritation. Common symptoms include frequent cough, wheezing, excess phlegm, and shortness of breath during everyday activities.
Pneumonia and Chest Infection
Pneumonia or lower respiratory infection may cause cough, fever, phlegm, chest pain, weakness, and breathing difficulty. Patients with older age, diabetes, heart disease, kidney disease, weak immunity, or chronic lung disease may need earlier evaluation.
Tuberculosis Related Respiratory Symptoms
TB remains an important respiratory concern in South Asia. A cough lasting three weeks or more, especially with fever, night sweats, weight loss, chest pain, or blood in sputum, should be checked medically.
Post-Viral or Post-COVID Cough
Some people continue coughing after a viral infection. However, if cough continues for weeks, worsens, or comes with breathlessness, wheezing, chest pain, or fatigue, a medical evaluation can help rule out asthma flare, pneumonia, airway inflammation, or other complications.
Allergy, Dust, Smoke, and Pollution-Related Symptoms
Kathmandu’s dust, smoke, seasonal allergens, construction exposure, and traffic-related air pollution can irritate the airways. People with asthma, COPD, allergic rhinitis, or sensitive airways may notice repeated cough, blocked nose, wheeze, or breathlessness.
Occupational Lung Problems
People exposed to dust, cement, chemical fumes, smoke, poultry dust, textile dust, paint, or welding fumes may develop repeated cough or breathing symptoms. A pulmonologist may ask about work exposure because symptoms may improve away from the trigger and worsen during exposure.
Sleep-Related Breathing Problems
Loud snoring, choking during sleep, daytime sleepiness, morning headache, and poor sleep may sometimes be related to sleep-disordered breathing. A pulmonologist may help assess whether further sleep evaluation is needed.
Symptom Guide: When to Monitor, When to Consult, When to Seek Emergency Care
| Symptom Pattern | Possible Concern | What to Do |
| Mild cough after cold, improving gradually | Viral irritation | Monitor, hydrate, avoid smoke/dust |
| Cough lasting more than 3 weeks | TB, post-viral cough, asthma, reflux, chronic infection | See a doctor or pulmonologist |
| Cough lasting 8 weeks or more | Chronic cough | Pulmonology evaluation recommended |
| Wheezing or repeated chest tightness | Asthma, COPD, airway narrowing | Consult a pulmonologist |
| Breathlessness during daily activity | Asthma, COPD, heart issue, anemia, lung infection | Medical assessment needed |
| Cough with fever and phlegm | Infection, pneumonia, bronchitis | See a doctor, especially if worsening |
| Blood in sputum | TB, infection, airway disease, other serious causes | Seek urgent medical care |
| Severe sudden shortness of breath | Emergency respiratory/cardiac problem | Go to emergency immediately |
| Bluish lips, confusion, fainting | Low oxygen or serious illness | Emergency care immediately |
What Tests May Be Recommended?
The tests depend on symptoms, age, medical history, physical examination, and risk factors. Not every patient needs every test.
At Nepal National Hospital, diagnostic services listed on the hospital’s services page include X-ray, PFT, ECG, ECHO, ultrasound, endoscopy, and laboratory support, which can help in respiratory and related evaluations.
Common tests may include:
Chest X-Ray
A chest X-ray may help check for pneumonia, TB-related changes, lung collapse, fluid, masses, or other visible lung and chest findings.
Pulmonary Function Test
A PFT helps measure how well air moves in and out of the lungs. It is commonly used in asthma, COPD, and other breathing problems.
Blood Tests
Blood tests may help assess infection, inflammation, anemia, allergy patterns, kidney function, or other medical conditions that can affect breathing.
Sputum Test
If there is phlegm, sputum testing may be advised to check for infection, TB, or other causes.
Oxygen Saturation
Pulse oximetry helps estimate oxygen level in the blood. Low oxygen with breathing difficulty needs urgent attention.
ECG or ECHO
Sometimes breathlessness is not only due to the lungs. Heart-related causes may need ECG or ECHO depending on symptoms and doctor’s evaluation.
Why Timely Pulmonology Evaluation Matters
Many people delay seeing a doctor because they think coughing is normal, breathlessness is due to age, or wheezing will settle on its own. Delay can allow asthma to remain uncontrolled, COPD to progress silently, pneumonia to worsen, or TB-like symptoms to spread risk to others.
Timely care helps in:
- Identifying the actual cause of cough or breathlessness
- Avoiding unnecessary antibiotics or repeated cough syrups
- Starting the right inhaler or medication when needed
- Checking inhaler technique and dosage
- Preventing repeated emergency visits
- Detecting infections early
- Supporting long-term lung health
A cough is a symptom, not a diagnosis. The right treatment depends on the cause.
Pulmonology Care at Nepal National Hospital, Kathmandu
Nepal National Hospital is located in Kalanki, Kathmandu, and provides respiratory care through its Department of Medicine. The hospital’s existing Pulmonology Hospital in Nepal page explains that pulmonology care at NNH includes consultation through the Department of Medicine, PFT, X-ray, laboratory support, and emergency/ICU pathways when higher-level care is needed.
The hospital also lists 24/7 emergency, 24/7 pharmacy, ICU, NICU, PICU, and other top services on its website.
For patients with sudden or severe breathing difficulty, emergency access matters. Nepal National Hospital’s multispecialty hospital page notes that its Emergency Department is located at Kalanki, is staffed by emergency physicians, supported by ambulance service, and has access to diagnostics, lab services, and specialists on call.
The hospital’s patient safety page also mentions respiratory safety measures such as negative pressure rooms and safe nebulization zones under General Medicine & Pulmonology.
When Should You Go to Emergency Instead of Waiting for OPD?
Visit emergency care immediately if you have:
- Sudden severe shortness of breath
- Chest pain with breathing difficulty
- Bluish lips or face
- Confusion, fainting, or extreme drowsiness
- Coughing up blood
- Oxygen saturation dropping, if measured
- High fever with breathing difficulty
- Severe asthma-like attack not improving with prescribed rescue medicine
- Breathlessness after choking, trauma, or allergic reaction
For routine consultation, patients can visit the Contact Nepal National Hospital page. The official contact page lists +977 01 5225101 / 5225103, email info@nationalnepalhospital.com.np, and location Kalanki, Kathmandu.
How to Prepare for a Pulmonologist Visit
To make your consultation more useful, note down:
- When the cough or breathlessness started
- Whether the cough is dry or with phlegm
- Color of phlegm, if present
- Fever, weight loss, night sweats, chest pain, or blood in sputum
- Smoking or smoke exposure history
- Dust, chemical, or workplace exposure
- Allergy history
- Past TB, pneumonia, asthma, COPD, or COVID history
- Current medicines, inhalers, and previous prescriptions
- Any chest X-ray, blood test, CT scan, or PFT reports
Bring your inhaler if you already use one. Many breathing problems worsen because the medicine is correct but the inhaler technique is not.
What You Can Do at Home While Waiting for Consultation
Home care cannot replace medical evaluation, but these steps may reduce irritation:
- Avoid smoke, dust, incense, strong perfume, and chemical fumes.
- Wear a mask in dusty or polluted areas.
- Drink enough fluids unless your doctor has restricted fluid intake.
- Take prescribed medicines as directed.
- Do not use antibiotics, steroids, or nebulization medicines without medical advice.
- Avoid smoking and second-hand smoke.
- Keep rooms ventilated and clean.
- Track symptoms, triggers, and timing.
- Seek urgent care if breathing worsens.
Final Takeaway
You should see a pulmonologist when cough lasts longer than expected, keeps returning, affects sleep, comes with wheezing, causes shortness of breath, or is associated with warning signs such as blood in sputum, chest pain, fever, weight loss, or worsening breathing.
A pulmonologist in Kathmandu can help identify whether the problem is asthma, COPD, infection, TB-related illness, allergy, post-viral cough, occupational exposure, or another cause. At Nepal National Hospital, Kalanki, pulmonology care is supported by the Department of Medicine, diagnostic services, emergency care, and hospital-based support when needed.
For cough and breathing problems, timely evaluation is safer than repeated self-medication.
