Pus Color Chart: Understanding the Different Colors and What They Indicate

Pus is a thick, yellowish or greenish fluid that is produced as a result of inflammation or infection in the body. It is composed of dead white blood cells, bacteria, and tissue debris. While pus is a sign that your body is fighting off an infection, the color of the pus can provide valuable information about the type and severity of the infection.

What Do Different Pus Colors Mean?

1. Yellow Pus

Yellow pus is the most common color and is usually associated with a bacterial infection. It indicates the presence of white blood cells, bacteria, and dead tissue. Yellow pus can be a sign of a mild infection, such as a pimple or a small wound, or a more serious infection, such as an abscess or cellulitis.

2. Green Pus

Green pus is often a sign of a more advanced infection. It is usually caused by the presence of a specific type of bacteria called Pseudomonas aeruginosa. Green pus can be seen in conditions such as ear infections, sinus infections, and wound infections.

3. Brown Pus

Brown pus is typically associated with old or chronic infections. It may indicate the presence of dead tissue or blood in the pus. Brown pus can be seen in conditions such as chronic abscesses or infected cysts.

4. Red Pus

Red pus is a sign of bleeding in the pus. It may indicate a more severe infection or the presence of a blood vessel injury. Red pus can be seen in conditions such as infected wounds or deep abscesses.

5. White Pus

White pus is usually seen in fungal infections, such as yeast infections or fungal nail infections. It may also indicate the presence of dead white blood cells and tissue debris.

6. Gray Pus

Gray pus is rare but can be seen in certain types of infections, such as tuberculosis or actinomycosis. It may indicate the presence of a specific type of bacteria or fungus.

When Should You Seek Medical Attention?

While the color of pus can provide some insight into the nature of an infection, it is important to remember that it is not a definitive diagnostic tool. If you notice any changes in the color, consistency, or smell of your pus, it is recommended to seek medical attention.

You should also seek medical attention if:

The area around the pus becomes increasingly red, swollen, or painful
You develop a fever
The pus is accompanied by other symptoms, such as fatigue or loss of appetite
The pus is not improving or is getting worse
