The Gross, and Sometimes Necessary, Reality of Pus

Pus is an unpleasant topic and one that is rarely spoken about. It is a fluid, usually yellow to off-white, which is made up of dead white blood cells and other forms of cellular debris. This article will explain what pus is and how it is made, as well as outlining some of the potential causes for pus formation.

What is Pus?

Pus is the result of a buildup of cells and fluids that occur as part of the body’s immune response. When a foreign invader enters the body, whether it be a virus, bacteria, parasite or fungus, the body will take certain actions to defend itself. These actions include sending white blood cells to fight the invader, which leads to inflammation. This inflammation causes a build-up of dead white blood cells, fluids and other debris which manifests as pus.

What Causes Pus?

Pus is usually caused by a bacterial infection. It can also be caused by parasitic or fungal infections, although this is less common. In some cases, pus can be caused by other irritants such as chemical irritation from a burn or allergic reaction. There are also some rare cases where pus can occur as a result of a type of cancer.

Treating Pus

It’s important to get pus checked out by a doctor. They may prescribe antibiotics or antifungals if a bacterial or fungal infection is identified. If the pus is the result of a chemical irritant or weakened immune system, different treatments may be recommended. It may also be necessary to use a warm compress to help break up the pus and/or perform drainage in order to remove it.

Final Thoughts

Pus can be an uncomfortable and unsightly side effect of certain infections and irritants, but it is usually a sign that the body is doing its job defending itself. It is important to get pus checked out by a medical professional in order to provide the correct treatment and to limit the possibility of further complications.
