What is the primary complication associated with untreated hidradenitis suppurativa?

The primary complication associated with untreated hidradenitis suppurativa is the formation of large abscesses. Hidradenitis suppurativa is a chronic skin condition characterized by the inflammation of hair follicles, often leading to painful lumps and abscess formation in areas such as the armpits, groin, and under the breasts. As the condition progresses without treatment, these abscesses can become larger, leading to increased pain, potential drainage of pus, and significant discomfort for the individual. The development of abscesses is a direct result of the blocked hair follicles and the inflammation in the skin, which can also lead to further complications such as scarring or even sinus tract formation if left unmanaged. While other complications may arise, the formation of large abscesses is a hallmark of untreated hidradenitis suppurativa and represents a significant concern for affected patients.
