‘IT'S NOT THE COUGH THAT CARRIED HIM OFF’
‘Doctor, I think I have a chest infection’ ‘Doctor, I have a cough that is keeping me awake at night’.
These are probably two of the most common causes for consultation in practice. Most coughs are due to self limiting viral infections and need no treatment apart from symptomatic support, but there are some symptoms that may indicate a more serious problem so –why do we cough? And what are the symptoms we need to be aware of?
A cough is an important defence reflex that allows removal of secretions and particles from the airways thus protecting against lower respiratory tract infections. Coughs may be acute (those present for less than 3 weeks) or chronic. In the former most are caused by infections or acute flare ups of a chronic condition such as asthma or obstructive airways disease. Chronic coughs can be caused by environmental irritation-such as smoking, or conditions affecting the lungs, other parts of the respiratory tract or some of you may be surprised to know- problems of the digestive tract such as acid reflux.
Most coughs do not require medical intervention-but what symptoms should you look for that may need further treatment or investigation?
1. Cough with a fever and production of sputum.
2. Cough persists over time (over 3 weeks)
3. Cough changes in character
4. Coughing blood
5. Shortness breath or difficulty breathing
6. Cough causing difficulties with day to day activities or disturbing sleep.
If you experience any of these symptoms please make an appointment to see your GP.
What home remedies may be helpful
Most of you will have realised that cough medicines are of limited use in the management of coughs. If they contain a sedative they may help you to sleep but recent research has shown chocolate had as much effect on reducing the symptoms of a cough than any cough remedy.(and more palatable to take though bad for the weight!)
Steam is a good remedy as the steam coats the airways and makes them less irritated. It also helps to reduce catarrhal problems especially when decongestants are added. So inhaling steam once or twice daily would be helpful. (In children a hot shower before bed may help them to sleep.)
Otherwise the advice is plenty of warm drinks and rest and seek help if there are any concerns.
