Causes and Risk Factors of Abscess
Abscesses are caused by obstruction of oil (sebaceous) glands or sweat
glands, inflammation of hair follicles, or from minor breaks and punctures
of the skin. Germs get under the skin or into these glands, which causes
an inflammatory response as your body's defenses try to kill these germs.
The
middle of the abscess liquefies and contains dead cells, bacteria, and
other debris. This area begins to grow, creating tension under the skin
and further inflammation of the surrounding tissues. Pressure and inflammation
cause the pain.
People
with weakened immune systems get certain abscesses more often. Those with
any of the following are all at risk for having more severe abscesses.
This is because the body has a decreased ability to ward off infections.
* Chronic steroid therapy
* Chemotherapy
* Diabetes
* Cancer
* AIDS
* Sickle cell disease
* Leukemia
* Peripheral vascular disorders
* Crohn disease
* Ulcerative colitis
* Severe burns
* Severe trauma
