What YOU Want To Know About Mucus

What YOU Want To Know About Mucus


Your body makes mucus all the time–and not just in your nose. Throughout the body, mucous membranes make roughly a quart of the stuff each day. Chances are you rarely think twice about all that goo until you catch a cold. That’s when nasal mucus secretions really ramp up, making your nose run like a faucet or causing thick congestion.

Annoying? You know it! But mucus is simply doing its job: defending, protecting, and cleansing your nasal passageways and keeping those delicate tissues moist, says Thomas Welch, MD, chief medical officer of Mercy Health in Toledo, Ohio. Here’s what you should know about all that snot.

What is mucus anyway?

Mucus is a slippery liquid containing water, proteins, and salt. Sugar-containing proteins (or glycoproteins) called mucins give mucus its gelatinous consistency. Discarded infection-fighting white blood cells plus other debris picked up in the nasal passageways often catch a ride in the mucus too.

Boogers are just dried up mucus (and other particles, like dirt, dust, and pollen). Post-nasal drip is mucus that runs down the back of the throat.

Where does mucus come from?

Your body is a mucus-making machine. Special cells and glands found in the thin lining (called the mucosa or mucous membrane) of body cavities and passageways leading out of the body regularly produce the slippery stuff.

You probably already know that mucus-secreting tissue can be found in the nose, mouth, throat, and lungs. But it’s also in our eyes, ears, GI tract, and reproductive and urinary organs.

Why do we make mucus?

Think of mucus in the respiratory system as “a film that protects the important parts of the inner nose and lungs,” says allergist and internist Tania Elliott, MD, chief medical officer at EHE, a New York City-based healthcare company specializing in preventive medicine. It keeps nasal passages (and lungs) well moisturized. “We don’t want those things dried out!” she says.

When a cold virus enters your nose, mucus production goes into overdrive, Dr. Welch explains. “It’s a reaction of the body against viruses, bacteria, or even particles of dust,” he says. It prevents those irritants from burrowing deeper into the lungs. Then, the tiny hairs in the respiratory tract called cilia help to sweep up the infected mucus like little brooms, says Dr. Elliott, so we can cough or blow it out.

Why does mucus get thicker when we’re sick?

Sometimes mucus gets thicker when we’re fighting off an infection. But it can also be thin and runny. It all depends on the type of virus or irritant activating the body’s mucus-producing tissues, explains Chandra Ivey, MD, a private-practice laryngologist and assistant clinical professor at the Icahn School of Medicine at Mount Sinai in New York City.

Smokers, for example, tend to have more mucus and thicker mucus, she says. In the case of a cold, a thicker wall of mucus can serve as a barrier preventing other viruses, bacteria, or irritating particles from entering the nasal membranes, she says.

Mucus can also get thicker if you’re taking certain medications that dehydrate your body, she adds. That’s another good reason to get extra liquids when you’re sick.

Why does mucus make it hard to breathe?

Stuffy nose? It’s usually the swollen mucosa–the mucus-generating tissue that lines your nose–that’s blocking your nasal passageways, not the mucus itself, Dr. Ivey says.

Other times, mucus can get thick like sludge, blocking the sinus cavities and preventing proper drainage, adds Dr. Elliott. “This leads to increased pain and pressure.”

What does a change in color mean?

Mucus is generally clear. If you have a cold, it can turn white or even yellow (especially if you’re dehydrated). A greenish hue may signal the presence of a greater number of infection-fighting white blood cells. But doctors say color alone isn’t a great indicator of a bacterial infection.

“It can turn yellow or green even with a virus,” notes Dr. Welch, who cautions against rushing to your doctor and begging for antibiotics. The vast majority of colds are viral, not bacterial. Antibiotics don’t fight viruses, and their misuse can lead to the development of new strains of bacteria that resist these medicines, he says.

A cold generally runs its course in a week, more or less. If you spike a fever, develop a cough, or have other signs that your condition is worsening, that’s when it’s time to call your doctor.

Do antihistamines or decongestants actually help?

These medicines are available over the counter in the form of pills, liquids, and nasal sprays. And while they may help ease cold symptoms, using them too often can make them less effective over time.

Antihistamines block inflammation, so there’s less tissue swelling and, in theory, less mucus production, Dr. Ivey says. Decongestants improve your breathing by constricting blood vessels in the area.

How does drinking extra fluids help?

Mom was right: You should feed your cold with plenty of liquids. Staying well hydrated can help thin out mucus so that it’s easier to expel.

But a lot of cough and cold medicines can be very drying, Dr. Elliott says. What’s more, when you’re sick and don’t feel like eating, your water intake naturally decreases. If you have a fever, you’re also losing fluid by sweating. Replenishing fluids is key, she says, to feeling better.

What else can I do to get rid of excess mucus?

Honey is a good mucus thinner, Dr. Ivey says. If you’re coughing up phlegm, try stirring some honey into a mug of tea. “It wraps around the little particles in the mucus and helps your body clear it,” she says.

Using a nasal irrigation device, like a neti pot, can help move mucus out of your nasal passages. “It washes it through,” Dr. Welch says.

As for medications, look for expectorants containing the active ingredient guaifenesin, which can bust up thick mucus, he says.

Dr. Elliott recommends adding eucalyptus to hot water and breathing in the humidified air or eating spicy foods. Both can naturally break up a stuffy nose.

The Little-Known Cause of Many Health Problems –

The Little-Known Cause of Many Health Problems -


Candida is another one of those things that I simply felt left out about. All of the sudden it became common knowledge that this fungus was in our bellies and causing some serious issues.

Here are some facts about Candida and the damage that it can do.

Candida is a type of yeast that naturally exists in the body. It’s a normal part of your gut bacteria, and is present in mucous membranes, on the skin, and in the birth canal (1).

Under normal circumstances, candida isn’t a problem and it coexists with the other bacteria in your intestinal tract. It’s only when candida grows and overpopulates your digestive system, that it can spread throughout the rest of your body and cause an infection known as candida overgrowth (2).

There are more than 20 different types of candida that can cause a fungal infection, but the most common is candida albicans, or C. albicans (2).

Candida is known as an ‘opportunistic’ fungus because given the right conditions, there’s no limit to where it will spread. This can cause serious damage to your organs and tissues, including the brain and kidneys (2). Once candida overgrowth gets to this point, it becomes a chronic health condition called systemic candida (3).

Candida is also the fungus responsible for causing thrush (oral candidiasis), which is common in babies, and vaginal yeast infections (4).

Symptoms of an overgrowth of Candida include;

  • Bad breath
  • Bloating, belching, intestinal gas, and/or abdominal pain
  • Constipation or diarrhea
  • Endometriosis or infertility
  • Fatigue and chronic fatigue
  • Frequent mood swings
  • Impotence
  • Insomnia
  • Loss of sexual desire or feeling
  • Muscle aches, weakness, or paralysis
  • Pain and/or swelling in joints
  • Poor memory, foggy thinking, or feeling “spacey”
  • Prostatitis
  • Troublesome vaginal itching, burning, or discharge

Candida overgrowth can be treated by huge changes in diet. It is necessary to cut out almost all sugars and starches to “starve” the fungus for a time. After elimination of Candida, all previous conditions and symptoms tend to disappear.
