Chronic bronchitis: symptoms, causes, treatment and which doctor to see
What chronic bronchitis is, how it differs from a passing chest cold, the causes common in India, the tests and treatments used, and when to get help.
Also known as: Bronchitis
What chronic bronchitis is
Chronic bronchitis is long-term inflammation of the bronchial tubes, the airways that carry air into and out of the lungs. The irritated lining swells and makes extra mucus, which narrows the airways and makes breathing harder. It is one of the two main forms of COPD (chronic obstructive pulmonary disease); the other is emphysema, and many people have features of both.
It is different from acute bronchitis, the chest infection that follows a cold and settles within a few weeks. Chronic bronchitis is usually described as a cough with phlegm on most days for months at a time, returning year after year. It tends to get slowly worse over time, but treatment and, above all, removing the cause can ease symptoms, slow the damage and keep people active.
Symptoms
Early on there may be few symptoms, and many people put a morning cough down to 'smoker's cough' or the city air. Common symptoms include:
- Cough with mucus (phlegm), often worst in the morning
- Wheezing, or a whistling sound when breathing
- Shortness of breath, first with exertion such as climbing stairs, later with everyday tasks
- Chest tightness
- Frequent chest infections, colds and flu that take longer to clear
In more advanced disease, people may lose weight, feel weak, and develop swelling of the ankles and feet because of strain on the heart. Symptoms often flare suddenly, usually with an infection or a spell of heavy pollution. These flares are called exacerbations and may need prompt treatment.
Causes and risk factors
Chronic bronchitis is caused by breathing in irritants over many years. The most important cause is tobacco smoke — cigarettes, bidis, hookah and other smoked tobacco — including second-hand smoke. In India, other causes are also important:
- Smoke from cooking or heating with wood, dung cakes, crop waste or coal, especially in poorly ventilated kitchens
- Outdoor air pollution in cities and near industry
- Dust and fumes at work, for example in construction, mining, stone quarrying, textile mills and some factories
- Age: symptoms usually begin in middle age, after years of exposure
- Rarely, an inherited condition called alpha-1 antitrypsin deficiency
- A history of severe chest infections or tuberculosis can also leave airways damaged
Because women who cook over open fires breathe smoke daily for decades, chronic bronchitis is not only a smoker's disease. Tell your doctor about cooking fuel and work exposure, not just smoking.
How it is diagnosed
Your doctor will ask about the cough, how long it has lasted, smoking and other exposures, and family history, and will listen to your chest. Tests commonly used include:
- Spirometry — a breathing test in which you blow hard into a tube. It measures how much and how fast you can breathe out, confirms whether the airways are narrowed, and helps separate COPD from asthma.
- Chest X-ray — to look for other causes of the symptoms, such as tuberculosis, pneumonia or a lung growth. A CT scan is sometimes used.
- Pulse oximetry — a clip on the finger that estimates the oxygen level in the blood.
- Blood tests — for example to check for anaemia or infection, or occasionally for alpha-1 antitrypsin deficiency. A sputum test may be done to rule out tuberculosis, which can cause a long-lasting cough.
Treatment
The lung damage cannot be fully reversed, but treatment can reduce symptoms, prevent flares and slow the decline. Your doctor will tailor the plan to how severe your symptoms are:
- Quitting smoking — the single most effective step at any age. Ask your doctor about counselling and medicines that help with quitting. Avoid second-hand smoke too.
- Bronchodilators — inhaled medicines that relax the muscles around the airways, making breathing easier. Some act quickly for relief; others are long-acting and taken every day.
- Inhaled steroids — added for some people, usually in combination inhalers, to reduce airway inflammation and flares.
- Pulmonary rehabilitation — a supervised programme of exercise, breathing techniques and education that improves stamina and confidence. A physiotherapist often leads it.
- Oxygen therapy — for people whose blood oxygen stays low, prescribed and monitored by a doctor.
- Vaccines — your doctor may recommend flu and pneumococcal vaccines, since chest infections hit people with chronic bronchitis harder.
Antibiotics or a short course of steroid tablets may be given during a flare caused by infection. Using an inhaler well matters as much as which inhaler you use: ask your doctor or pharmacist to watch your technique, and ask whether a spacer would help.
Living with chronic bronchitis
- Use a cleaner cooking fuel such as LPG where possible, and keep kitchens ventilated
- On high-pollution days, limit time outdoors and avoid exercising near traffic
- Use protective masks and follow safety rules if your work involves dust or fumes
- Stay active within your limits; walking daily keeps breathing muscles stronger
- Eat well; ask about nutrition if you are losing weight
- Agree a written plan with your doctor for what to do when symptoms flare
When it is an emergency
Call 112 or 108, or go to the nearest emergency department, if you or someone with chronic bronchitis has:
- Severe breathlessness, or being unable to speak in full sentences
- Blue or grey lips or fingertips
- Confusion, unusual drowsiness or difficulty staying awake
- Chest pain, or a fast or irregular heartbeat
- Breathlessness that does not ease with the usual reliever inhaler
See a doctor within a day or two if phlegm becomes thicker or changes colour, you develop a fever, or you need your reliever inhaler more than usual. Coughing up blood, losing weight without trying, or night sweats should also be checked promptly.
Which doctor to see
A general physician can assess a long-lasting cough and arrange first tests. A pulmonologist, also called a chest physician, confirms the diagnosis with spirometry, plans long-term treatment and pulmonary rehabilitation, and manages severe disease. You can find pulmonologists in Bengaluru or general physicians in Bengaluru on The Doctor Index.
Questions to ask at your appointment
- Do I have chronic bronchitis, asthma, or both?
- Have I had spirometry, and what did it show?
- Am I using my inhaler correctly?
- Which vaccines should I have?
- What should I do, and whom should I call, when my symptoms flare?
Common questions
Questions people ask
- Is chronic bronchitis the same as COPD?
- Chronic bronchitis is one form of COPD. COPD is the umbrella term for long-term lung diseases that block airflow, mainly chronic bronchitis and emphysema. Many people have both, and the treatment approach is largely the same, guided by spirometry and symptoms.
- Can I get chronic bronchitis if I have never smoked?
- Yes. Years of breathing smoke from wood, dung or coal cooking fires, heavy outdoor pollution, or dust and fumes at work can all cause it. Second-hand smoke also contributes. Tell your doctor about these exposures, as they shape both diagnosis and advice.
- Is chronic bronchitis contagious?
- No. Chronic bronchitis is caused by long-term irritation of the airways, not by an infection you can pass on. The chest infections that cause flares can spread to others, though, so cover coughs and wash hands, especially around children and older relatives.
- Will quitting smoking help if I already have chronic bronchitis?
- Yes. Quitting is the most effective way to slow the disease at any stage. Cough and phlegm often lessen after stopping, and the rate at which lung function declines slows down. Your doctor can support you with counselling and medicines to help you quit.
This condition is usually assessed by a pulmonologist. Every profile shows the doctor’s registration and what has been checked.
Pulmonologists in Bangalore
A few pulmonologists listed on The Doctor Index. They are shown because of their speciality, not a stated interest in Chronic Bronchitis; ask the clinic whether the doctor sees it.
