Causes and Risk Factors for Hidradenitis
The bacterium Staphylococcus aureus is usually involved in the condition, and Proteus species are often involved in chronic cases. Bacteria called coagulase-negative staphylococci (CNS) have also been associated with these infections.
There seems to be a genetic predisposition for the disease, and it seems to be more common in women. Hidradenitis suppurative does not appear in people who have not reached puberty because the sweat glands are not active, but it can appear at any age afterward.
Hidradenitis suppurativa affects people who are extremely overweight (obese) at a higher rate than the general population. Cigarette smokers also have a higher incidence of this disorder than nonsmokers. Researchers have not yet found the connection.
