What physiological condition can result from ascending too quickly during a dive?

Ascending too quickly during a dive can lead to Decompression Illness (DCI), which encompasses a range of physiological symptoms resulting from nitrogen bubbles forming in the body due to rapid changes in pressure. As a diver descends, nitrogen from the breathing gas dissolves into body tissues. If a diver ascends too quickly, the reduction in pressure causes the dissolved nitrogen to come out of solution and form bubbles. These bubbles can cause various symptoms, including joint pain, dizziness, respiratory problems, and in severe cases, can affect the central nervous system or cardiovascular system. Therefore, it's crucial for divers to follow proper ascent rates and safety stops to allow their bodies time to safely eliminate excess nitrogen and mitigate the risks associated with DCI.
