Most coughs clear up within 3 weeks and don't require any treatment. A dry cough means it's tickly and doesn't produce any phlegm (thick mucus). A chesty cough means phlegm is produced to help clear your airways.
"A cough is considered chronic if it persists longer than eight weeks," explains Dr. Safdar. "At that point, we start to worry whether the cause might be a chronic health condition that needs to be addressed."
Coughs that persist after a common cold or other upper respiratory infection are called post-infectious or post-viral coughs. They can linger for three to eight weeks after a viral infection.
The four main types of coughs are: wet, dry, paroxysmal and croup. Most coughs do go away on their own.
Speak to a GP if:
your cough is particularly severe. you cough up blood. you experience shortness of breath, breathing difficulties or chest pain. you have any other worrying symptoms, such as unexplained weight loss, a persistent change in your voice, or lumps or swellings in your neck.
While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.
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.
Call your doctor if your cough (or your child's cough) doesn't go away after a few weeks or if it also involves any one of these: Coughing up thick, greenish-yellow phlegm. Wheezing.
You should see a doctor if your cough brings up yellowish-green phlegm or blood. A cough that doesn't produce mucus is called a dry or nonproductive cough. Acute cough is the least serious type of cough. It only lasts for three weeks or less and will most likely clear up on its own.
In addition to lab tests, sputum or mucus from a cough can be visually examined to determine whether bronchitis is viral, bacterial, or both. Clear or white mucus often indicates a viral infection, while yellow or green mucus may suggest a bacterial infection.
Coughing often worsens at night because a person is lying flat in bed. Mucus can pool in the back of the throat and cause coughing. Sleeping with the head elevated can reduce the symptoms of postnasal drip and GERD. Both can cause coughing at night.
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.
Common symptoms of pneumonia include: a cough – which may be dry, or produce thick yellow, green, brown or blood-stained mucus (phlegm) difficulty breathing – your breathing may be rapid and shallow, and you may feel breathless, even when resting. rapid heartbeat.
The most common causes of chronic cough are postnasal drip, asthma, and acid reflux from the stomach. These three causes are responsible for up to 90 percent of all cases of chronic cough. Less common causes include infections, medications, and lung diseases.
Antibiotics are only used to treat bacterial chest infections. They're not used for treating viral chest infections, like flu or viral bronchitis. This is because antibiotics do not work for viral infections. A sample of your mucus may need to be tested to see what's causing your chest infection.
See a GP if:
you've had a cough for more than 3 weeks (persistent cough) your cough is very bad or quickly gets worse – for example, you have a hacking cough or cannot stop coughing. you feel very unwell. you have chest pain.
What is a heart cough? In heart failure, your heart muscle has dysfunction that might be due to weak contraction or stiffness. This can allow fluid to back up in yout lungs, creating a condition called pulmonary edema. Your body coughs persistently in an effort to eliminate the excess fluid.
So you've been coughing for a while, and instead of getting better, it seems like your cough is getting worse. Maybe you've even started coughing up phlegm or have pain in your chest when you cough. Those are signs your cough might actually be pneumonia.
A chronic cough is when a cough lasts longer than 8 weeks in adults or 4 weeks in children. Common causes include asthma, allergies, gastroesophageal reflux disease (GERD), or bronchitis. Less commonly, it can be a sign of a more severe condition, such as heart or lung disease.
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.
