Bronchitis is inflammation of the bronchi — the main airways that carry air into the lungs. Acute (short-term) bronchitis is common and usually develops after a viral infection such as a cold or [flu](https://healthanswers.co.uk/conditions/flu/). It often sounds worse than it is, and most people recover fully. ## Symptoms The main symptom is a [cough](https://healthanswers.co.uk/symptoms/cough/), which may bring up clear, yellow or greenish mucus. Other symptoms can include: - a [sore throat](https://healthanswers.co.uk/conditions/sore-throat/) and a blocked or runny nose - [wheezing](https://healthanswers.co.uk/symptoms/wheezing/) or breathlessness - tiredness and aches - a mild [fever](https://healthanswers.co.uk/symptoms/high-temperature/) The cough can persist for a few weeks even after other symptoms have gone. ## What causes it Most cases of acute bronchitis are caused by the same viruses that cause colds and flu. Smoking and breathing in irritants such as fumes or dust can also inflame the airways and make bronchitis more likely or longer-lasting. ## Treatment Acute bronchitis usually clears up on its own. To help yourself recover: rest, drink plenty of fluids, and use [paracetamol](https://healthanswers.co.uk/treatments/paracetamol/) or ibuprofen for fever and aches. Stopping smoking is one of the most helpful things you can do. [Antibiotics](https://healthanswers.co.uk/treatments/antibiotics/) are generally not recommended because the infection is usually viral and they make little difference to recovery. ## When to get it checked See a GP if your cough lasts more than three weeks, keeps coming back, or you cough up blood, and seek urgent help if you become very breathless or have [chest pain](https://healthanswers.co.uk/symptoms/chest-pain/). People with existing heart or lung conditions should seek advice sooner. ## ! When to see a GP about bronchitis See a GP if a cough lasts more than 3 weeks, you keep getting bronchitis, you cough up blood, or you have a long-term heart or lung condition. Get urgent help if you are very breathless, have chest pain, a very high temperature, or are coughing up blood-stained or rusty-coloured mucus. ## Common questions about bronchitis What is the difference between acute and chronic bronchitis? Acute bronchitis is a short-term infection that usually clears up within a few weeks. Chronic bronchitis is a long-term condition, often part of COPD, usually linked to smoking, where the cough and mucus persist over time. How long does bronchitis last? The main infection often settles within a week or two, but the cough can linger for up to 3 weeks or sometimes longer. A cough lasting beyond 3 weeks should be checked. Do I need antibiotics for bronchitis? Usually not. Most cases are caused by viruses, so antibiotics make little difference. A GP may consider them if you are at higher risk of complications or there are signs of a bacterial infection. How can I ease bronchitis symptoms? Rest, drink plenty of fluids, and treat any fever or aches with paracetamol or ibuprofen. Some people find honey or steam soothing. Stopping smoking helps your airways recover and reduces the chance of it returning. ## Sources - [NHS — Bronchitis](https://www.nhs.uk/conditions/bronchitis/) ## How we reviewed this page Medically reviewed by the [HealthAnswers UK doctor review panel](https://healthanswers.co.uk/our-doctors/) First published 19 February 2026 Medically reviewed 3 July 2026 Next review due 3 July 2029 or sooner if NHS or NICE guidance changes Written by HealthAnswers editorial team.
