What are the causes of cough with mucus?
Viruses cause colds. You cough because your body is trying to get rid of mucus that's full of germs. You’re more likely to get a cold in cooler months. But you can get one at any time of year.
A cough coupled with body aches could be a sign of a more serious illness. The flu, caused by the influenza virus, can have symptoms similar to a cold. But you’ll usually feel a lot worse when you have the flu. You could have fever, chills and muscle aches.
This “chest cold” usually lasts about three weeks. It makes you cough because the airways in your lungs swell and make a lot of mucus. This kind of inflammation usually shows up after a viral infection. But bacteria can cause bronchitis, too.
A lung infection - which is what pneumonia is - can make your air sacs fill up with fluid or pus. You may cough up a lot of green or yellow mucus. It may have blood in it. Usually, bacteria cause pneumonia. But fungal or viral infections, like the flu, can bring it, too.
If you find yourself coughing every night, it may be a sign of postnasal drip. That’s when mucus drips down the back of your throat.
Chronic Obstructive Pulmonary Disease (COPD)
You might make more mucus than normal when you have COPD. Your airways and air sacs can also stop working the right way. That’s because they get hurt or inflamed.
Smoking cigarettes is the most common cause. But it can happen because of air pollution, asthma, or your genes.
Your cough could be a sign of a genetic condition. If you have cystic fibrosis (CF), you cannot clear out mucus very well. Bacteria can grow inside all that phlegm. That could give you a higher chance of getting other lung infections, which can also make you cough.
Your airways can get loose and scarred. When this happens, mucus can get stuck. Your body coughs to move it out of your lungs. Cystic fibrosis is just one condition that leads to bronchiectasis. It can also happen after a lung infection, like pneumonia or tuberculosis. Blockages like tumors can also cause it. Sometimes, you’re born with it.97
