What condition is caused by the formation of gas bubbles in the body due to rapid ascent?

Decompression sickness, commonly known as "the bends," occurs when a diver ascends too quickly after being at depths where the pressure is significantly higher. At these depths, inert gases like nitrogen dissolve into the body tissues and fluids. As a diver ascends rapidly, the decrease in pressure can cause these dissolved gases to come out of solution and form bubbles. These bubbles can then obstruct blood vessels and cause a variety of symptoms that may affect the cardiovascular, respiratory, and nervous systems, leading to potentially serious and life-threatening conditions if not treated promptly.

Understanding this process is crucial for divers, as it emphasizes the importance of ascending slowly and performing safety stops to allow gases to be safely eliminated from the body. Recognition of the signs and symptoms of decompression sickness is also vital for effective management and treatment.
