Emergency: If you are coughing up large amounts of blood, feel breathless, are dizzy, or have chest pain, call 108 or go to the nearest emergency room now. Do not wait to book a clinic appointment.
Coughing Up Blood (Hemoptysis): Causes, Emergency Triage, and Treatment in Hyderabad
Written by Dr. Kunal Waghray, MD DM DNB MNAMS EDRM, Interventional Pulmonologist, Respire Airway Clinics, Hyderabad. Last reviewed 13 May 2026.
Coughing up blood is one of the most frightening things a person can experience. The cough comes, the tissue turns red, and the mind goes straight to the worst possibilities. I have sat with hundreds of patients in this exact moment, and the most useful thing I can tell you in the first minute is this: not every episode of blood in the cough is an emergency, but every episode needs investigation, and the right next step depends entirely on how much blood you saw.
In Hyderabad and across India, tuberculosis remains the single most common cause of hemoptysis. That matters, because most online articles you will read are written for a Western audience where cancer and bronchitis dominate the list. The Indian picture is different.
This page tells you how to decide whether to go to the emergency room now or to book a clinic appointment this week, what is most likely causing the bleeding, and how an interventional pulmonologist in Hyderabad investigates and treats it.
Is This an Emergency? Triage in the Next Five Minutes
Before anything else, look at how much blood you have actually coughed up.
| What you saw | Medical name | What to do |
|---|---|---|
| A red streak or pink tinge in phlegm | Blood-streaked sputum | Book a clinic appointment within the week. Not an immediate emergency. |
| Clear red or clotted blood, a teaspoon to several tablespoons | Frank hemoptysis | Seek same-day medical review. Go to an urgent care clinic or emergency room. |
| Large volume bleeding, more than roughly a cup over 24 hours | Massive hemoptysis (more than 200 to 300 ml in 24 hours) | Medical emergency. Call 108 or go to the nearest emergency room now. |
If you are unsure how much you coughed up, assume the higher tier. If the bleeding is bright red and continuous, that is more concerning than dark, old, brown-stained sputum. If you feel breathless, dizzy, or your heart is racing, that is an emergency regardless of the visible volume.
What Hemoptysis Actually Is, and What It Is Not
Hemoptysis is blood that comes up from the lungs or airways, brought out by coughing. Both the spellings hemoptysis (American) and haemoptysis (British and Indian medical writing) refer to the same thing.
Two situations are often confused with hemoptysis and need to be ruled out first.
Nosebleed. Blood from the back of the nose can drip into the throat and be coughed out. The patient swears it came from the chest, but the source is the nose. A simple ENT examination can confirm this.
Haematemesis, which is vomiting blood from the stomach or upper digestive tract. It is usually darker, sometimes described as coffee-ground, and comes up with retching rather than coughing.
True hemoptysis comes up with a cough, is bright red and often frothy because it is mixed with air, and is sometimes followed by a metallic taste.
What Causes Coughing Up Blood in India
In Indian clinical practice, a handful of conditions account for the vast majority of cases. Listed in order of frequency, not in the order Western textbooks use.
Tuberculosis, active and post-TB
In Indian case series, tuberculosis is consistently the leading cause of hemoptysis, including in patients who have already completed TB treatment. In active TB, the infection erodes small blood vessels in the lung tissue. In post-TB lungs, even after the bacteria are cleared, the lung is left scarred and often contains cavities or distorted airways. These scarred areas can bleed years later, sometimes decades after the original infection.
Bronchiectasis
Bronchiectasis is permanent damage to the airways, usually from a previous severe infection. The airways become wider, scarred, and prone to repeated infection and bleeding. In India, post-TB bronchiectasis is one of the commonest forms.
Lung cancer
Lung cancer can cause hemoptysis when a tumour erodes into a nearby blood vessel. This is the diagnosis patients fear most when they see blood, and it is the one we work hardest to confirm or exclude in any older smoker. It is not the most common cause, but it is the one that changes the outcome most when it is missed.
Aspergilloma (fungal ball)
A fungal ball, most often caused by Aspergillus, can grow inside an old TB cavity or a bronchiectatic airway. These fungal balls have a particular tendency to bleed, sometimes heavily. Aspergilloma is an India-relevant cause precisely because of the high background rate of post-TB cavitary lung disease.
Mitral stenosis and cardiac causes
A narrowed mitral valve raises pressure in the pulmonary veins, which can cause small vessels in the lung to bleed. This remains relevant in younger Indian patients with rheumatic heart disease.
Why You Should Not Wait, Even if the Bleeding Has Stopped
A single small episode of hemoptysis that settles on its own is reassuring in the short term. It is not reassuring in the long term.
Patients often tell me they had a streak of blood three months ago, decided to wait and see, and only came in when it happened again. By that point a chest X-ray often shows a cavity, a mass, or scarring that has been present and progressing the whole time.
Hemoptysis is a symptom of an underlying problem. The bleeding can stop while the cause continues. Investigation is the only way to know whether you are dealing with healed TB scarring, an active infection, a fungal ball, a tumour, or something else.
How Hemoptysis Is Investigated
The investigation has a predictable sequence, and patients usually feel better just from understanding what comes next.
History and examination. The history matters more than most investigations. How much blood, how often, for how long, smoking history, TB history, family TB contact, and current medication.
Chest X-ray and sputum tests. The first imaging test is almost always a chest X-ray. It will show many causes but will miss small lesions and central airway problems. Sputum is sent for TB testing using GeneXpert or smear, routine bacterial culture, and sometimes cytology.
CT scan of the chest. A high-resolution CT scan is the most useful single test in the workup of hemoptysis. It identifies bronchiectasis, masses, cavities, fungal balls, and vascular abnormalities.
Bronchoscopy. For a clear explanation of what bronchoscopy is, see our patient guide. In hemoptysis, bronchoscopy serves two purposes at once: it locates the source of the bleed, and it provides a platform for treatment.
Stopping the Bleed: Endobronchial Treatment
When the bleeding is mild to moderate and the source can be reached with the bronchoscope, several endobronchial techniques can stop or slow the bleeding.
Endobronchial adrenaline. A small volume of dilute adrenaline solution is delivered to the bleeding airway through the bronchoscope. The adrenaline constricts the small vessels and often slows or stops the bleed within minutes.
Argon plasma coagulation (APC). Uses a stream of ionised argon gas to deliver heat to the bleeding tissue without direct contact. Particularly useful for tumour-related bleeds and bleeding from the airway wall.
Balloon tamponade. For larger bleeds where the source is localised to one segment, a small balloon can be inflated inside the bleeding airway to compress the vessel from the inside. This protects the rest of the lung from flooding while the patient is stabilised for definitive treatment.
Bronchial Artery Embolisation: When Bronchoscopy Is Not Enough
For larger bleeds, recurrent bleeds, or bleeds where the source cannot be controlled with endobronchial techniques, bronchial artery embolisation (BAE) is the next step.
BAE is performed by an interventional radiologist. A small catheter is passed through an artery in the groin or wrist, threaded up to the bronchial arteries that supply the bleeding part of the lung, and the bleeding vessel is blocked from the inside using tiny particles or coils.
Published series report immediate bleeding control in roughly 80 to 90 percent of patients undergoing BAE. The role of the interventional pulmonologist in a BAE case is to confirm the bleeding side with bronchoscopy first, stabilise the airway, and coordinate the timing of the embolisation with the radiology team.
Frequently Asked Questions
Is coughing up blood always an emergency?
No. Streaks of blood in phlegm need urgent investigation but are not an immediate emergency. Frank blood, several teaspoons or more, needs same-day medical review. Massive bleeding, roughly a cup or more in 24 hours, is a medical emergency and requires immediate hospital care.
What is the most common cause of hemoptysis in India?
Tuberculosis, both active TB and old post-TB scarring, is the leading cause in Indian case series. Bronchiectasis and lung cancer follow. This is different from Western countries, where bronchitis and lung cancer dominate.
Can tuberculosis cause coughing up blood years after treatment?
Yes. Scarring and cavities left behind by treated TB can bleed years or even decades later, often without active infection. This is one of the most common scenarios seen in our clinic.
Is coughing up blood always a sign of cancer?
No. Cancer is one cause among several, and in India it is not the most common one. TB, bronchiectasis, and fungal infection of old TB cavities are all more frequent. Cancer must always be excluded, especially in smokers and older patients, but it should not be assumed.
Can bronchoscopy stop bleeding in the lungs?
Yes, for many patients. Endobronchial adrenaline, argon plasma coagulation, and balloon tamponade are all techniques performed during bronchoscopy that can stop or slow airway bleeding. For larger bleeds, bronchial artery embolisation by an interventional radiologist is the next step.
How is hemoptysis investigated in Hyderabad?
The workup typically includes a focused history, chest X-ray, sputum testing for TB and infection, a CT scan of the chest, and bronchoscopy where indicated. At Respire, the bronchoscopy and CT pathways are coordinated so the patient does not have to chase multiple appointments.
How much blood is too much to manage at home?
More than a teaspoon of frank, bright red blood in a single episode is enough to warrant same-day medical review. More than a few tablespoons, or any sustained bleeding, is an emergency. If you are also breathless, dizzy, or in pain, treat it as an emergency regardless of volume.
If you are coughing up large volumes of blood now, call 108 or go to the nearest emergency room. This page is for patients whose bleeding has stopped or who are coughing only streaks of blood. Emergency cases are not clinic cases.
If you have coughed up blood and the bleeding has settled, do not assume the problem has resolved. Book a same-week consultation with Dr. Kunal Waghray at Respire Airway Clinics. Bronchoscopy and CT pathways are coordinated in-house, and most patients have a clear diagnosis within a week of the first visit.
