What increases susceptibility to decompression sickness?

All of the listed factors contribute to an increased susceptibility to decompression sickness, which occurs when dissolved gases (mostly nitrogen) come out of solution and form bubbles in the bloodstream and tissues as a diver ascends too quickly.

Age can be a significant factor because as individuals grow older, their bodies may have altered physiology, including changes in circulation and tissue composition, which may affect gas exchange during diving.

Obesity is another risk factor because excess weight can increase the amount of nitrogen stored in fat tissues. During a rapid ascent, nitrogen may be released more readily from these tissues, increasing the risk of bubble formation and decompression sickness.

Dehydration is also critical. When the body is dehydrated, blood volume decreases, and this can affect circulation and the efficiency of nitrogen elimination. Dehydrated divers are at a higher risk of developing decompression sickness due to compromised physiological processes that help manage nitrogen levels.

Considering these factors as a collective risk enhances the understanding of how physiological conditions can impact susceptibility to this potentially dangerous condition.
