So here's the big question: Should you spit or swallow your phlegm? Even though it might taste nasty, “there's nothing wrong with swallowing it,” Dr. Comer says. In fact, that's probably what your body expects you to do, which is why phlegm naturally drains down into the back of your throat.
If your mucus is dry and you are having trouble coughing it up, you can do things like take a steamy shower or use a humidifier to wet and loosen the mucus. When you do cough up phlegm (another word for mucus) from your chest, Dr. Boucher says it really doesn't matter if you spit it out or swallow it.
So, to answer your questions: The phlegm itself isn't toxic or harmful to swallow. Once swallowed, it's digested and absorbed. It isn't recycled intact; your body makes more in the lungs, nose and sinuses. It doesn't prolong your illness or lead to infection or complications in other parts of your body.
Steam: You can use a device such as a cool-mist humidifier or steam vaporizer to breathe in warm air. You can also take a hot shower or breathe in vapors from a pot of simmering water. These methods introduce moist air into your air passages, which helps loosen the mucus in your lungs.
Hold your breath for 3 to 5 seconds. Then—as you let that breath out [coughing]— cough 2 or 3 times. Push on your belly with your arms as you cough. [coughing] Breathe in slowly and gently through your nose, and repeat the coughing if you need to.
If GERD causes you to cough up phlegm, then you might need antacids or other medications that relieve acid reflux symptoms. Your cough may go away on its own in a few days. But if you've been coughing up phlegm for two weeks or more and your symptoms haven't improved, schedule an appointment with a healthcare provider.
If you're suffering from allergies, asthma or another condition that is causing excess mucus production, it's important to seek medical treatment. However, in cases where phlegm results from a viral infection, such as the common cold, it will usually resolve on its own within seven to 10 days.
The abnormal bronchi then become filled with excess mucus, which can trigger persistent coughing and make the lungs more vulnerable to infection. If the lungs do become infected again, this can result in further inflammation and further widening of the bronchi.
It is a common symptom of conditions such as the common cold, sinusitis, and allergies. The excess mucus can be caused by inflammation or swelling of the nasal passages, which can be due to a variety of factors such as viral or bacterial infections, allergies, or irritants in the air.
Though they're always at work, you typically only notice the sticky substances when you're sick. Mucus and phlegm are similar, yet different: Mucus is a thinner secretion from your nose and sinuses. Phlegm is thicker and is made by your throat and lungs.
When mucus starts to build up or trickle down the back of the throat, this is known as postnasal drip. Causes of postnasal drip include infections, allergies, and acid reflux. As well as feeling the need to clear the throat frequently, a person with postnasal drip may also experience: a sore throat.
“And if you're normal and healthy, you never feel it and you just swallow it.” The mucus, together with the bacteria and other trapped substances, then goes to the stomach and eventually pass out of the body. Your body makes a lot of mucus, although no one's quite sure how much. Mucus is mostly water.
You may notice that mucus from your runny nose has become thicker, with a yellow or green tinge. This usually is due to a spike in the number of white blood cells your immune system has dispatched to overcome the virus, according to the Mayo Clinic.
When phlegm rises from the lungs into the throat, the body is likely trying to remove it. Spitting it out is healthier than swallowing it.
Green or Yellow Mucus
It's no reason for concern, and in fact, it means your body is working extra hard to fight off infection. White blood cells rush to battle infection, and when they've done their job, they get flushed out of the body along with the virus.
Coughing actually helps you clear the infection more quickly by getting rid of the phlegm from your lungs. Antibiotics aren't recommended for many chest infections, because they only work if the infection is caused by bacteria, rather than a virus.
You may find that you are still coughing up phlegm or mucus after an infection with COVID-19 (coronavirus). This is normal after respiratory infections. It is how the lungs and airways keep themselves clear.
Even if you're coughing up yellow or green phlegm, you might not need antibiotics. Your mucus color alone can't tell you if a virus or bacteria is causing your cough. If your cough lasts longer than 3 weeks, it's time to see a healthcare provider. You may need an X-ray or antibiotics.
Common Symptoms of Mucus Buildup in the Lungs:
Difficulty Sleeping. Sore Throat. Chest Congestion. Cough that Produces Phlegm.
If your cough is frequent or productive (you're coughing up phlegm) and interferes with your ability to breathe properly when your heart rate is up, you should consider resting until the cough has improved.
Phlegm is a thick mucus from the lower airways due to lung inflammation or injury. Infection is a common cause, but other conditions like allergies, lung disease, and GERD can cause a productive cough. Treatment depends on the underlying cause and includes supportive care and medications.
