Similar to brown snot, black nasal mucus can be the result of dried blood or from inhaling something dark like cigarette smoke, smog or dust. However, in some cases, it could also be a symptom of a fungal infection, which tend to affect those with a compromised immune system.
Black snot might be a sign of a potentially serious fungal infection. There are a few different types of fungal infections that could affect the sinuses, which would require medication or at times, surgery, to heal.
Clear or light-colored mucus often does not indicate a serious health problem, but when a person has black mucus or phlegm, they should see a doctor as soon as possible. Though black phlegm is not always a cause for concern, it could be a sign of lung cancer or exposure to a pollutant.
Black. This is typically experienced by heavy smokers or people who live in highly polluted areas. In rare cases, black snot can be a sign of fungal infection. If you notice this color when you blow your nose, you should consult a doctor.
Green and cloudy: viral or bacterial infection
A lot of the symptoms of viral infections – fever, cough, headache, loss of smell – overlap for COVID-19 and other viral infections like the flu, respiratory syncytial virus and the common cold.
Cloudy or white mucus is a sign of a cold. Yellow or green mucus is a sign of a bacterial infection. Brown or orange mucus is sign of dried red blood cells and inflammation (aka a dry nose).
Exposure to pollution, irritants, or mold spores that you could inhale increases your risk for diseases that produce black mucus.
It's often associated with coal miners and others frequently exposed to coal dust—black phlegm can be a sign of pneumoconiosis or black lung disease,” Kalodner says. If you're not a smoker or aren't usually around coal dust, black phlegm could mean you have a yeast infection known as exophiala dermatitidis.
You cannot get rid of black mucus if you continue to smoke. Your respiratory system has tiny hair-like structures called cilia that help particles move out of your respiratory passage. If you stop smoking, these structures can get better and remove mucus that can be black or brown in color.
Mucus is usually clear, gray, or white. Green or yellow mucus may be a sign of an infection. Brown mucus can affect people who smoke and those with black lung disease, which results from exposure to coal dust. Mucus that contains blood may be pink or red.
Poor oral hygiene is often the leading cause of tartar buildup. For tartar to turn black or form below the gum line, improper brushing and flossing is usually the culprit. Additionally, certain other factors contribute to the rate of tartar formation and can turn it black; these include: Smoking.
Black Fungus or mucormycosis is a rare but dangerous invasive fungal infection caused by a group of molds called mucormycetes. Black fungus commonly affects the sinuses and lungs but can affect skin and brain. People can get infected when they inhale the mold spores or touch the mold spore.
When a mold fungus finds its way into the sinus cavity, the immunity in the body reacts by releasing a chemical known as oesinophils to fight the fungi. This substance is what causes fungal sinusitis and will cause irritation for as long as the fungi are within the sinus.
Mucormycosis, also known as black fungus, is a rare but dangerous infection. It's caused by a group of molds called mucormycetes and often affects the sinuses, lungs, skin, and brain. You can inhale the mold spores or come into contact with them in things like soil, rotting produce or bread, or compost piles.
Yellow mucus
This can mean a cold or infection that's progressing. The yellowish tinge comes from white blood cells that rush to the site of the infection and then are swept away after working to fight it off. “Yellow or green snot can sometimes mean that you have an infection,” Dr. Sindwani says.
White Mucus
If a virus makes its way into your nose and into the air-filled pockets behind your forehead, cheeks and nose — called the sinuses — your nose may start to make extra mucus to clear out the virus. After a few days, it might begin to turn white.
Mucus can turn different colors for a variety of reasons. White snot can occur with a cold, for example, and pink boogers can be a sign of pregnancy. And while green or yellow snot may indicate a bacterial infection—and a need for antibiotics—it can also signal that your body is on the mend.
While brown mucus is sometimes caused by dried blood or dirt in the nasal passage, it can also be an indicator of bronchitis, which happens when the tubes that carry air to your lungs become inflamed. If you cough up brown mucus or phlegm, contact your physician immediately.
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.
Black-pigmented sputum, also called “melanoptysis,” is a symptom that may be observed in certain pathologies such us coal workers' pneumoconiosis (anthracosis).
Brown Phlegm
Really dark brown, tenacious phlegm is seen in patients who have cystic fibrosis or bronchiectasis, which is a chronic lung disease. The phlegm is brown because of blood and the intense chronic inflammation that comes with the chronic disease state.
