What is a potential consequence of untreated frostbite?

Untreated frostbite can lead to tissue necrosis or gangrene because the cold temperatures cause ice crystals to form in the cells, damaging them and impeding blood flow. When the affected tissue does not receive adequate blood supply, it cannot get the necessary oxygen and nutrients, leading to cell death. As the condition worsens, not only does the tissue become non-viable, but gangrene may set in, which often necessitates surgical intervention, such as amputation, to prevent further health complications. Recognizing the severity of frostbite early can significantly mitigate these risks, highlighting the importance of prompt medical care for anyone exhibiting symptoms of frostbite.
