Toxic megacolon is a serious medical condition characterized by inflammation of the colon and the formation of deep ulcers. It is considered a life-threatening emergency and often requires prompt hospitalization and treatment. The words "toxic" and "megacolon" are often used interchangeably to describe the condition, but there are several other terms that can be used to refer to this medical emergency. These may include fulminant colitis, acute colitis with toxic dilation, or simply toxic colitis. Regardless of the terminology used, swift medical intervention is critical for successful treatment and a positive patient outcome.
