Mucus is part of our daily reality, helping to keep our noses clean and swabbed of bacteria — but it can also be an indicator that something is wrong with our respiratory system.
When you start noticing bright yellow snot, it’s time to ask, “What does yellow mucus mean and what could be causing it?” From there, it’s time to seek treatment.
If your mucus comes out as any color other than clear, it likely means you’re contending with some type of infection whether it’s a sinus infection, bacterial infection, viral infection, or fungal infection. Each infection slightly varies in characteristics so it’s important that you pay close attention to your symptoms and seek medical advice to make sure you receive the correct diagnosis and care.
Is yellow mucus a sinus infection?
Not always. Yellow mucus is typically indicative of an infection of some kind although it may not always be from sinusitis. Identifying any accompanying symptoms can help you understand what type of infection your yellow mucus is caused by.
So, if yellow snot isn’t always caused by a sinus infection, what kind of infection is yellow mucus?
What does yellow mucus mean?
In terms of sinus infection mucus color, green and yellow mucus typically means that you have some type of infection in your system and your body has started fighting back. In fact, the unusual snot color actually comes from the dead white blood cells that did their part to stave off the virus, bacteria, fungus, or other intruders that are causing your illness. More often than not, green or yellow mucus indicates a cold, one of the most common infections you can experience in your respiratory system.
Green mucus tends to be thicker than yellow snot because your immune system is being pushed harder, meaning that there are even more dead white blood cells in what’s being excreted. In other words, green snot tells you that you should stay diligent and pay close attention to how your body feels and what medications are working to relieve symptoms. You may want to consider seeking professional medical attention to see what other treatment options are available.
Yellow or green mucus becomes a signifier of a sinus infection when the underlying sickness, such as a cold, moves on to infect the sinuses. Sinus infections normally go away on their own using over-the-counter solutions within 10 days to several weeks, meaning you likely won’t be experiencing constant green snot for months.
When to seek treatment for yellow mucus
If you are experiencing constant green snot for months or your symptoms otherwise worsen over time, then it is recommended that you seek medical intervention. It could indicate that the underlying virus or bacteria is spreading or growing stronger despite your attempts to stave it off.
Though extremely rare, an unaddressed sinus infection can cause permanent brain damage and even death. Don’t let a sinus infection that doesn’t respond to treatment drag on; sometimes you can’t “just wait it out.” A sinus specialist can diagnose a chronic or otherwise severe sinus infection and propose prescriptions, or even surgery, to fix the issue at hand.
Symptoms of a sinus infection
A sinus infection can sometimes be difficult to detect because it shares symptoms with other respiratory conditions in addition to originating with a different infection entirely. If you’re starting to suspect that your cold or other illness has worsened into a sinus infection, your primary care physician or a sinus specialist can give you a proper diagnosis and treatment plan.
The most common sinus infection symptoms include, but are not limited to, the following:
- Nasal inflammation
- Difficulty breathing through your nose
- Excess mucus
- Post-nasal drip
- Sinus headaches or pressure
- Sore throat
- Dental pain
- Ear infections
Because colds and other infections usually spread to the sinuses rather than originating there, the sinus headaches and intense sensations of pressure are particularly notable signs that your starting condition has worsened. Similarly, your mucus going from yellow to green also tips you off that your immune system is being overtaxed fighting the infection. Get rest, stay hydrated, and speak with your doctor about what over-the-counter or prescription options are available to fight off whatever illness discolored your snot.
