When we’re feeling under the weather, our body gives us some pretty obvious signs that we’re sick. For example, a sore throat, fever, and congestion are all common symptoms of a cold or flu. But there’s another telltale sign that can help us identify what type of sickness we have: the color of our mucus.
Yes, mucus. That slimy substance that we often find disgusting is actually an important part of our body’s immune system. It acts as a protective barrier, trapping germs, dust, and other particles that we inhale or ingest. But when we’re sick, our body produces more mucus than usual to help flush out those harmful substances.
So, what does the color of our mucus tell us about the type of sickness we have? Let’s take a closer look.
Clear Mucus
If your mucus is clear, it typically means that your body is still in the early stages of fighting off an infection. Clear mucus is a sign that your body is doing its job of trapping and flushing out germs and other irritants. However, if you’re experiencing other symptoms such as a sore throat or congestion, it’s likely that you’re dealing with a mild cold or allergies.
Yellow or Green Mucus
Yellow or green mucus is a sign that your body is in the later stages of fighting off an infection. The color comes from white blood cells, which contain a greenish enzyme that helps break down foreign particles. When your body is producing more white blood cells than usual, as is the case when you’re sick, this enzyme can give your mucus a yellow or green tint.
So, what type of infection causes yellow or green mucus? Most commonly, it’s a sign of a bacterial infection, such as sinusitis or bronchitis. Bacterial infections often produce thicker mucus than viral infections, which is why the color may be more pronounced.
It’s important to note that not all yellow or green mucus is a sign of a bacterial infection. If you have a cold or flu, you may also experience yellow or green mucus as your body fights off the virus. However, if you’re experiencing other symptoms such as a fever or body aches, it’s best to see a doctor to rule out a bacterial infection.
Brown or Black Mucus
Brown or black mucus is a sign that there is old blood in your mucus. This can be caused by a variety of factors, such as smoking, air pollution, or even a sinus infection. If you’re experiencing brown or black mucus, it’s important to see a doctor to determine the underlying cause.
In rare cases, brown or black mucus can be a sign of a fungal infection, which requires prompt medical attention. If you have a weakened immune system or are taking medication that suppresses your immune system, you may be more susceptible to fungal infections.
Pink or Red Mucus
If your mucus is pink or red, it’s likely that there is blood in your mucus. This can be a sign of a variety of conditions, such as a sinus infection, allergies, or even a nosebleed. However, if you’re experiencing pink or red mucus and you’re also coughing up blood or experiencing chest pain, it’s important to see a doctor immediately.
In rare cases, pink or red mucus can be a sign of a more serious condition such as tuberculosis or lung cancer. If you’re experiencing these symptoms, it’s important to seek medical attention right away.
