What symptoms may indicate decompression sickness?

Joint pain, dizziness, difficulty breathing, and fatigue are common symptoms associated with decompression sickness, often referred to as "the bends." When divers ascend too rapidly, dissolved gases (mainly nitrogen) can form bubbles in the bloodstream. This results in various physiological issues that manifest as specific symptoms.

Joint pain is frequently reported due to nitrogen bubbles accumulating in joint tissues, causing severe discomfort. Dizziness occurs as gas bubbles can affect the inner ear or disrupt normal blood flow to the brain. Difficulty breathing can arise if bubbles obstruct blood vessels in the lungs, leading to respiratory distress. Fatigue often accompanies these other symptoms as the body reacts to the physiological stresses caused by the condition.

Understanding these symptoms is critical for divers, as early recognition and appropriate response can significantly affect the outcome of decompression sickness.
