Abscess Causes

An abscess is a cavity containing pus that is generally surrounded by inflamed tissue. Abscesses most commonly are caused by localized infections resulting from microorganisms, such as viruses, bacteria and even fungi (in rare cases). These microorganisms kill the local cells, resulting in an inflammatory response from the white blood cells. Most abscesses last for four to five days before they burst and the pus drains out. Sometimes, however, medical treatment is needed.

Formation

• The formation of an abscess is a defensive mechanism meant to prevent the further spread of an infection to other parts of the body through the bloodstream. The most common areas where abscesses develop are the groin, armpits and rectal region; however, they can develop in other parts of the body as well.

Infections

• Infections caused by bacteria such as staphylococci are one of the most common reasons for abscess formation. These infectious bacteria generally cause obstruction of the oil (sebaceous) and sweat glands, resulting in an inflammatory response from the body, thus leading to the development of an abscess to prevent further spread of the infection.

Steroids

• Another common cause of abscesses is exposure to regular and continuous steroid therapy. Steroid therapy is useful in treating various inflammatory reactions of the body; however, it sometimes causes various side effects including the development of abscesses by disrupting the oil secretion of the sebaceous glands.

Foreign Materials

• Certain foreign materials such as splinters and needles can cause infections, thus leading to abscesses as part of the body's defensive mechanism.

Other Causes

• Medical conditions such as diabetes, cancer and kidney failure, insect bites and open wounds also can lead to abscesses.
