Bronchitis

Bronchitis is the inflammation of the larger airways in your lungs, causing an ongoing cough.

Bronchitis can be caused by viruses, bacteria, or breathing in smoke or dust.

Acute bronchitis can last for weeks, whereas chronic bronchitis lasts for months and may come back each year.

Chronic bronchitis is usually related to smoking.

Most people with acute bronchitis will feel better with time and rest, with a number of treatments available to help ease the cough and other symptoms.

If you think you have bronchitis, your doctor can assess you and discuss treatment.

Who is at risk of developing bronchitis?
People at risk include:

the elderly
people breathing in irritating chemicals
smokers
those with a lung condition, such as asthma
people with poor immunity
You can reduce your risk by hand washing, and if you smoke, cutting down or quitting. The annual flu vaccine is recommended for people with chronic bronchitis.

Is bronchitis contagious?
Mostly, bronchitis is caused by contagious viruses. These can be spread by air when someone coughs, or by touch after the virus is left on a surface.

Hand washing, covering your mouth when coughing and staying home while unwell can reduce the spread.

Do I need a chest X-ray?
An X-ray is usually not necessary. The Royal Australian College of General Practitioners recommend that chest X-rays for bronchitis are best avoided for simple cases. For more information, speak to your doctor or visit the Choosing Wisely Australia website.

Bronchitis treatment
Most people with acute bronchitis will feel better with time and rest.

You can help ease the cough and other symptoms by:

inhaling steam or having a warm bath
avoiding cigarette smoke and other irritants
drinking plenty of fluids
simple pain relief medication, such as paracetamol (follow the directions on the label)
a teaspoon of honey at night, either by itself or in warm water
Cough medicines are available, but they might or might not help.

If you are very unwell or not getting better, or if you get worse, see your doctor
