My parents are worried about an increased risk of decompression sickness because of my age. There are several caveats, however. Boys this age have narrow hips and are vulnerable to weight belt slipping during suit compression, even at relatively shallow depths. The epiphyseal plates near the ends of long bones are the major sites of new bone growth during development, and are very susceptible to injury or damage. If a DCS event occurred, it would be more likely to damage long bone growth in a boy of 16 than a girl who has completed her skeletal development and growth.
Physical maturity is one thing, intellectual maturity is another.
Being physically able and comfortable with the heavy gear can be a real problem with a child's buoyancy, one of the most important skills in safe diving. Healing of these is highly variable but usually require six to eight weeks before returning to full activity. Couple this with the need for conditioning, complete wound healing and the possibility of need for blood regeneration, and a period of eight weeks would be advised before diving. A post-op hemoglobin determination should be performed, and if it shows you are anemic, you should have that corrected before you dive. Complications might include wound disruption, hernia and hypoxia from anemia.
