Question: 1 / 400

What are common symptoms of decompression sickness?

Joint pain, dizziness, and skin rashes

Joint pain, dizziness, and skin rashes are common symptoms of decompression sickness, which occurs when a diver ascends too quickly, causing nitrogen bubbles to form in the body due to a rapid reduction in pressure. Joint pain, often referred to as "the bends," is particularly classic, as the nitrogen bubbles can accumulate in the joints and soft tissues, leading to significant discomfort. Dizziness can result from a reduction in blood supply or other physiological changes that accompany decompression. Skin rashes, though less commonly discussed, can indeed be a symptom due to bubbles affecting various tissues in the body. Recognizing these symptoms is crucial for prompt treatment and management of decompression sickness, as early intervention can significantly improve outcomes. Understanding these symptoms helps divers identify a potential medical issue and seek help quickly following a dive.
