What Are the Causes of Abscesses?
Experts refer to reddened, painful skin swellings with a collection of pus in the lower skin layer as an abscess or boil. Doctors speak of abscesses when the pus-filled area is encapsulated and a new cavity has formed in the skin tissue.
Characteristic of abscesses is that the pus accumulation is not visibly recognizable on the surface, the inflammation is located within the skin, and there is no drainage to the outside. This happens, for example, when skin pores are blocked by sebum or dirt, or when a wound has been inadequately treated. In such cases, bacteria have an easy time.
Accordingly, even a seemingly inflamed pimple can be a small abscess. An abscess develops when, for example, germs enter the skin and multiply in the tissue. The body’s immune system triggers an inflammatory response and attempts to fight the pathogens.
As a result of this reaction, an accumulation of liquid or viscous pus forms at the affected site. This consists of depleted white blood cells that form during the fight against the skin inflammation. The pus contains killed and often still living pathogens. For health-threatening reasons, it should therefore not remain in the skin or spread further.
