Phlegm and Mucus: How To Get Rid of It

They serve a purpose, but too much is uncomfortable

Excessive mucus and phlegm may not be much of a conversation starter (unless you’re 14 and trying to spit the farthest). But if you have too much mucus, it can drive you crazy in search of solutions.

First, consider that mucus has a purpose. This fluid is naturally made by your body every day, says laryngologist Paul C. Bryson, MD.

“While the exact amount your body makes isn’t known, most experts think it’s about one liter a day,” he says. (That’s half of a 2-liter bottle of soda!)

Dr. Bryson outlines some ways to get rid of your excess mucus and phlegm.

What are mucus and phlegm?

Mucus has an important role in your body. It’s made by cells in your mouth, throat, nose and sinuses. Its slippery consistency helps protect and moisturize, and traps potential irritants.

Phlegm is made of mucus membranes, but it’s produced and used by your respiratory system to combat inflammation.

What causes mucus overproduction?

Your body can go into overdrive creating mucus when you:

  • Have a cold.
  • Have irritated sinuses (sinusitis).
  • Have allergies.
  • Are exposed to smoke or other toxins in the air.

“Environmental allergies can cause excess mucus or phlegm, as can food allergies, but the latter is harder to diagnose based on this symptom alone,” Dr. Bryson explains.

If you’re healthy, your mucus tends to be thin — and you may not even notice it. But if you’re sick, your mucus can become thick and crusty.

And you may not notice phlegm until you cough it up, which can be a symptom of pneumonia or bronchitis.

You may be concerned about the color of your mucus and phlegm, too, whether it’s yellow or green. But the color doesn’t necessarily mean you have an infection.

How to get rid of excess mucus and phlegm

If you have chronic problems with mucus and phlegm, try the following. These remedies also help if your problem with mucus and phlegm progresses to a postnasal drip.

Hydrate more

Drink more water. Also, consider your medications or any dehydrating beverages you regularly drink like coffee, alcohol and some teas.

“A good rule of thumb is to drink enough water to make your urine pale,” Dr. Bryson advises.

Use a humidifier

This can help your body moisturize your throat and nasal passages and may help you reduce mucus and phlegm production.

Opt for a cool-mist humidifier and make sure you clean it regularly per its directions.

Check filters on heating and cooling systems

Make sure the filters are clean and functioning well to keep dust and other potential irritants out of the air.

Use a nasal saline spray

This helps rinse and hydrate tissues in your nose and sinuses. Use a sterile spray that has sodium chloride.

Gargle with salt water

Using salt water (1 teaspoon of salt per glass of warm water) can ease your irritated throat by clearing away mucus.

Use eucalyptus

Whether it’s a eucalyptus balm or essential oil in a diffuser, the scent of eucalyptus can help loosen mucus in your chest.

Use over-the-counter medication

Decongestants (in oral form or as a nasal spray) can help reduce the swelling in your nose. There are also expectorants like guaifenesin (like Mucinex®) that help thin mucus.

“If you’re concerned about allergies, remember that the testing is easy and straightforward,” says Dr. Bryson. “You can also try over-the-counter allergy medications, which may solve your issue.”

If you’re in doubt, don’t hesitate to discuss your problem with your primary care doctor or an otolaryngologist, who can dig into your particular symptoms and history to find solutions.

Is excess phlegm a sign of a serious condition?

If the amount of mucus your body makes is uncomfortable, you might worry it’s a sign of a more serious problem.

According to Dr. Bryson, mucus isn’t typically a symptom to worry about if it’s your only symptom.

“Worrisome signs are mucus accompanied by fevers, chills and night sweats, especially if you also experience weight loss, nasal obstruction or intermittent nose bleeds for more than two weeks,” he says.
