A cough is a reflex action to clear your airways of mucus and irritants such as dust or smoke. It's rarely a sign of anything serious. Most coughs clear up within 3 weeks and don't require any treatment.
A chesty cough may follow a common cold infection or can be due to long-term conditions, such as bronchiectasis, chronic bronchitis or asthma. Whooping cough (pertussis) can result in coughing fits, and there can be a loud 'whoop' noise at the end of the cough when the person tries to breathe in again.
If you have a dry cough, a preparation containing an antitussive such as dextromethorphan or pholcodine is the most suitable to try. If you have a chesty cough, a preparation containing an expectorant such as guaifenesin or ipecacuanha is the most suitable to try.
A dry cough is one of the most common coronavirus symptoms, but some people may have a cough with phlegm (thick mucus).
Does coughing up mucus mean you're getting better? In most cases, coughing up mucus means your body is working to fight off an infection, and it is in the healing stages. Drink plenty of fluids to help thin the mucus.
There are no specific tests for bronchitis, but your doctor may do blood tests to eliminate other possible causes of your symptoms. Your doctor may also order a chest x-ray if you have a fever. This is to rule out pneumonia. COVID-19 is diagnosed with a viral test.
A bronchitis cough sounds like a rattle with a wheezing or whistling sound. As your condition progresses, you will first have a dry cough that can then progress towards coughing up white mucus.
Often viral cases of pneumonia begin as congestion and cough with or without fever in the first few days. When a doctor listens to the lungs and finds breathing sounds are not clear on either side of the chest, a viral cause over bacterial is even more highly suspected.
See a GP if you have a chest infection and:
you feel very unwell or your symptoms get worse. you cough up blood or blood-stained mucus. you've had a cough for more than 3 weeks.
Chest infections are common, especially after a cold or flu during autumn and winter. Although most are mild and get better on their own, some can be serious or even life-threatening.
Dozens of conditions can cause a recurrent, lingering cough, but the lion's share are caused by just five: postnasal drip, asthma, gastroesophageal reflux disease (GERD), chronic bronchitis, and treatment with ACE inhibitors, used for high blood pressure and heart failure.
It is best to see a doctor for coughs that persist for longer than 3 weeks, as a cough that won't go away may indicate something more serious. A cough occurs when the lungs or airways become irritated. The most common cause of a cough is the common cold, which does not usually require medical attention.
Take a breath that is slightly deeper than normal. Use your stomach muscles to make a series of three rapid exhalations with the airway open, making a "ha, ha, ha" sound. Follow this by controlled diaphragmatic breathing and a deep cough if you feel mucus moving.
Occasional coughing is normal as it helps clear your throat and airway of germs, mucus and dust. A cough that doesn't go away or comes with other symptoms like shortness of breath, mucus production or bloody phlegm could be the sign of a more serious medical problem.
Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Most people DO NOT need antibiotics for acute bronchitis caused by a virus. The infection will almost always go away on its own within 1 week. Doing these things may help you feel better: Drink plenty of fluids.
The symptoms of a chest infection are more likely to include coughing and bringing up phlegm. An upper respiratory tract infection may cause a cough, but it can also produce symptoms such as sneezing, a blocked or runny nose and a sore throat. The effects of a chest infection will also tend to last a little longer.
