A gluteal abscess is an infection of the buttocks area. Risk factors for this type of infection include poor hygiene, skin irritation, trauma, diabetes, HIV, obesity, and certain medical conditions such as Crohn's disease. Poor hygiene habits like not showering after exercising or not changing wet clothing can increase the risk of bacterial or fungal growth. Skin irritation can be caused by tight clothing, shaving, waxing, or other practices which can set the stage for infection. Trauma to the area can occur from everything from sporting activities to sitting for long periods of time, and can lead to an infection. Diabetes and HIV can impair the body's ability to fight off infection, making it easier for an abscess to form. Finally, obesity is a risk factor for gluteal abscess due to the accumulation of sweat, bacteria, and fungi in the area.
