As we descend deeper in water, the pressure around our bodies increases, causing nitrogen to be absorbed into our body tissues.

If the pressure is reduced too quickly, however, the nitrogen comes out of solution and forms bubbles in the tissues and bloodstream. This commonly occurs as a result of violating or approaching too closely the diving table limits, but it can also occur even when accepted guidelines have been followed.
