Why is Snot Green When Sick?

Snot is one of the most fascinating substances known to the human body. However, snot is not something that any of us like to analyze – unless you work in a lab. It’s one of the things you can expect to come out of your body when you’re sick. A sinus infection and a runny nose are certainly some of the most unpleasant feelings. What is snot and why is snot green when you are sick?

Why is Snot Green When Sick?

Overproduction of mucus can signal allergies, but green snot almost always signals that your body is fighting off an infection.

Why is this?

This is what you should know about mucus, how it works, and why snot is green when you are sick.

How Mucus Works

Mucus is the body’s way of creating a protective barrier between the most sensitive parts of your body – and everything else. When you are sick or your body’s immune system responds to stimuli like pollen, you produce more of this nasal mucus in an attempt to guard the body.

While mucus isn’t always beneficial, it has a point in trying to protect the body from infection. The consequence of this, unfortunately, is the overproduction of the mucus in question when you are ill.

When people get sick, the overproduction of snot is a likely consequence that can point to respiratory infection, allergies, common colds, or flu. There are other things it could mean if the duration of the infection continues.

When Should I See a Doctor or an Urgent Care in Omaha?

The best time to see a doctor is when you first have any symptoms. The first sign of snot, especially different from what you would normally experience, means that you should see a doctor. Doctors or Urgent Care Clinics in Omaha can prescribe anti-mucus drugs and/or antibiotics. Certain medications can reduce the amount of snot your body is producing and simultaneously take care of the infection causing the overproduction of mucus.

When Should I See a Specialist?

If you have already been through a course of antibiotics and your problems persist (or return shortly after), then it might be time to see a specialist. Doctors will often refer patients to a specialist when they suspect there is a more advanced infection or a larger problem that needs to be treated.

The specialist you will be referred to depends on what your doctor suspects. However, a referral to an ear, nose & throat (ENT) specialist from your doctor is common as a first step.

What is Snot?

Snot is produced by the body’s mucus membranes as a protective measure against infection. It is important to note that mucus can also spread infection around. When snot is clear, it is a likely immunity response. On the other hand, when the color of mucus has turned to something else (yellow or green mucus), it is a sign that the body is trying to expel something more serious.

Why is Snot Green When Sick?

Snot turns green when we’re sick due to something called myeloperoxidase. Often, this is a chemical that accompanies a cold, the flu, or any general respiratory infection that affects the body. The presence of green snot means that it’s not just a reaction but potential expulsion, and the time for antibiotics might be now.

See a doctor for medical advice, diagnosis, or treatment if you experience any reaction that you aren’t used to, even where it’s not accompanied by any of the other symptoms that you might expect.

Does Green Snot Mean You Need Antibiotics?

Many people believe that green snot means you need antibiotics right away, but that isn’t always true. Green or yellow mucus usually means your immune system is hard at work fighting off a virus like the common cold or flu. Antibiotics are only effective for bacterial infections, not viral ones, and taking them unnecessarily can cause side effects and even contribute to antibiotic resistance.

If your symptoms last more than 10 days, suddenly get worse after starting to improve, or you experience severe facial pain, swelling, or a high fever, it may be time to visit an urgent care clinic in Omaha. Otherwise, green snot alone does not mean you need antibiotics.

When to see a doctor for green snot:

Symptoms last more than 10-12 days
Symptoms suddenly get worse after starting to improve
You experience severe facial pain, swelling, or high fever (over 101°F)
You have chest pain, difficulty breathing, or cough up blood

What About Blood in Snot?

Snot isn’t just either clear or green, but might also turn other shades due to several other reasons. Grey or brown mucus could indicate the presence of dust particles. In some cases, dark brown, or black mucus could also indicate the presence of blood. Surprisingly, blood in mucus does not always present itself as the bright red most people imagine. Purple mucus is possible, though this is extremely rare and usually related to medication.

If you have been blowing your nose often, blood in your snot could indicate that the force or frequency has caused something to rupture. Both spotting and a full bleed indicate that you need medical help and assessment.

What Does Clear Snot Mean?

Clear mucus is likely to mean either irritation due to allergies, or irritation as a result of other factors. If you are producing more clear snot than you believe you should, then schedule an appointment with your doctor or visit an urgent care near you. Seek a referral to a specialist if the problem continues or worsens.

Is Green Snot Contagious?

Green snot by itself does not always mean you are highly contagious, but many illnesses that cause colored mucus, such as colds, flu, or COVID-19, are most contagious during the first few days of symptoms. During this time, it is best to stay home if possible and take precautions to avoid spreading germs. Washing your hands often, covering your mouth when coughing or sneezing, and wearing a mask in public if you are actively sneezing or coughing can help protect others while you recover.
