What Is a Complication?

A complication is an unexpected medical problem that develops during or after an illness, injury, surgery, or medical treatment. Complications may range from mild and temporary to serious or life-threatening, depending on the underlying condition and the individual’s overall health.

Early recognition and prompt treatment can often reduce the severity of complications and improve recovery.
