What kind of doctor treats Acute Bronchitis?
A primary care doctor (your regular doctor) usually treats acute bronchitis. A pulmonologist (a lung doctor) may help if you keep getting bronchitis or if you have another lung disease. Most cases get better on their own. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is acute bronchitis?
Acute bronchitis is swelling and irritation of the bronchial tubes. These are the large airways that carry air to your lungs. Many people call it a chest cold. It comes on suddenly and is short-term.
The infection usually lasts a week to 10 days. But your cough can last for several weeks after the infection is gone. Acute bronchitis is different from chronic bronchitis, a long-term disease that is part of COPD (a lung disease that makes it hard to breathe). Acute bronchitis usually does not cause any permanent breathing problems.
Symptoms
The main symptom is a cough. Sometimes it is a dry cough. Often you cough up mucus (sputum). Other symptoms can include:
- Feeling tired.
- Congestion (a stuffy nose).
- A sore throat.
- Mild body aches.
- Wheezing, a whistling sound when you breathe.
- Chest tightness.
- Shortness of breath.
- A low fever.
The swollen airways get narrower, so less air can pass through. This can cause wheezing and chest tightness. Symptoms of acute bronchitis last less than 3 weeks. The infection usually lasts a week to 10 days, but the cough can continue for several weeks.
Causes and who gets it
A virus usually causes acute bronchitis. The same viruses that cause colds and the flu often cause it. Bacteria can sometimes cause a chest cold too. One example is whooping cough (pertussis).
Breathing in lung irritants can also cause acute bronchitis. These include tobacco smoke, fumes, dust, and air pollution. You are more likely to get it if you have close contact with someone who has a virus. Your risk is also higher if you are not immunized against the flu, RSV, COVID-19, or pneumococcal disease (a bacterial infection). Young children, older adults, and people with major health conditions are the most at risk.
How doctors diagnose it
To diagnose acute bronchitis, your doctor will ask about your symptoms and listen to your breathing. You may also have other tests. Whooping cough and pneumonia (a lung infection) can have similar symptoms, so doctors think about those too.
Treatment
Acute bronchitis usually gets better on its own, without antibiotics. Antibiotics will not help you feel better if you have a chest cold. Even when bacteria are the cause, they are not recommended. To feel better, you can:
- Get plenty of rest.
- Drink plenty of fluids.
- Use a clean humidifier or cool mist vaporizer.
- Breathe in steam from a bowl of hot water or a shower.
- Use pasteurized honey to relieve cough for adults and children at least 1 year old.
- Use acetaminophen to treat fever. Adults can also take aspirin.
You may need inhaled medicine, which is medicine you breathe in, to open your airways if you are wheezing. Ask a health care professional about over-the-counter medicines that can help you feel better.
When to see a doctor
See a health care professional if you have any of these:
- A fever that lasts longer than 5 days, or a fever of 104 F or higher.
- Cough with bloody mucus.
- Shortness of breath or trouble breathing.
- Symptoms that last more than 3 weeks.
- Repeated episodes of bronchitis.
Call 911 or go to the emergency room if you have shortness of breath or trouble breathing. See a health care professional for any symptom that is severe or concerning.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can evaluate your cough, listen to your lungs, and check your breathing. If you need a lung specialist, they can refer you to one.
Common questions
Is acute bronchitis contagious?
Usually, yes. The viruses that cause it spread through the air when people cough. They can also spread through physical contact, for example on unwashed hands. Wash your hands often and cover your coughs and sneezes.
Do I need antibiotics?
Probably not. Antibiotics will not help you feel better if you have a chest cold. Even when bacteria are the cause, they are not recommended. If you have whooping cough or pneumonia instead, a health care professional will most likely prescribe antibiotics.
How long does acute bronchitis last?
The infection usually lasts a week to 10 days. The cough can continue for several weeks. Symptoms last less than 3 weeks. See a health care professional if they last longer.
How is it different from chronic bronchitis?
Acute bronchitis is sudden and short-term, and it usually leaves no permanent breathing problems. Chronic bronchitis is a long-term disease that is part of COPD, a lung disease that makes it hard to breathe.
