Bronchitis is an inflammation of the tubes that carry air to your lungs (bronchial tubes). It usually causes a cough that brings up mucus, and it often happens after a cold or the flu. A urine test is sometimes used to help rule out other illnesses or check for infection, but it is not a main test for bronchitis.
Key facts
Yes, acute bronchitis is very common, especially in the fall and winter. Most adults have at least one episode every few years.
Acute bronchitis can affect people of all ages, but it is more common in young children and older adults. People with weakened immune systems or chronic health problems are also at higher risk.
Bronchitis is usually diagnosed by a healthcare provider based on your symptoms and a physical exam. They will listen to your lungs with a stethoscope and may ask about your cough, fever, and other signs. A urine test is not a common test for bronchitis, but your doctor might order it if they suspect another infection (like a urinary tract infection) or want to check your kidney function if you are dehydrated.
Treatment for acute bronchitis focuses on relieving symptoms and letting your body fight off the infection. Most cases are caused by viruses, so antibiotics do not work. For chronic bronchitis (a form of COPD), treatment involves long-term management to improve breathing and reduce flare-ups.
For most people, bronchitis is a short-term illness that goes away with rest and home care. If you have chronic bronchitis (a type of COPD), managing it means taking medications as prescribed, avoiding triggers, and keeping up with regular check-ups. You may need to use inhalers or other breathing treatments daily.
Eat a balanced diet with plenty of fruits and vegetables to support your immune system. Stay hydrated. Gentle exercise, like walking, can help your lungs work better when you are feeling better, but rest during the acute illness. For chronic bronchitis, talk to your doctor about a safe exercise plan.
You can lower your risk of bronchitis by avoiding viruses and lung irritants. Frequent hand washing, staying away from sick people, and not smoking all help. Keeping your immune system strong with good nutrition, sleep, and exercise also reduces your chances of getting severe illness.
Vaccines can help prevent some infections that lead to bronchitis. Make sure you are up to date on the flu vaccine (annual), the pneumonia vaccine (if recommended for your age or risk group), and the COVID-19 vaccine. Ask your healthcare provider which vaccines are right for you.
There is no routine screening test for bronchitis. If you have a cough that lasts more than 3 weeks, or if you have a history of chronic lung disease, your doctor may suggest a lung function test (spirometry) to check for conditions like COPD.
The outlook for acute bronchitis is very good – most people recover completely within a few weeks. For chronic bronchitis, it is a long-term condition, but with proper treatment and lifestyle changes, many people manage their symptoms well and maintain a good quality of life.

The doctor will ask about your symptoms, medical history, and any exposures (like smoking or sick contacts). They will use a stethoscope to listen for wheezing or crackling sounds in your lungs. If a urine test is ordered, you will be asked to provide a clean urine sample in a small cup. The results usually come back quickly. For bronchitis, the diagnosis is often based on your history and exam rather than a specific test.
If your doctor thinks a bacterial infection is present, they may prescribe antibiotics. For severe cough, they might recommend a cough medicine that helps you cough up mucus (expectorant) or one that calms a dry, hacking cough (cough suppressant). Inhaled medications (like bronchodilators) can help open up your airways if you are wheezing. Always talk to your doctor before taking any new medicine, especially if you have other health conditions.
Surgery is not used for bronchitis. If bronchitis becomes chronic or leads to complications like lung damage, other treatments (like pulmonary rehabilitation) may be needed, but not surgery.
Having a lingering cough or breathing trouble can be frustrating and may cause worry or low mood. It is normal to feel anxious, especially if you have trouble sleeping or miss work. Talk to your doctor if you feel down or very anxious – they can connect you with support.
