Nothing is actually bent when you are suffering from decompression sickness. The term bent or the bends comes from the history behind decompression sickness. The reason for the term “The Bends” was used is because the afflicted individuals characteristically bent forward at the hips. The bends (decompression sickness (DCS) or Caisson disease) occurs in scuba divers. It occurs when gases dissolved in the body (mostly nitrogen) come out of solution in bubbles. Being ‘bent’ can affect just about any part of the body including the skin, your joints, the lungs, the heart and brain.
