At what depth can you get decompression sickness?

How deep can you dive before you have to decompress or at what depth you can get decompression sickness may depend on a number of factors. These factors include the divers’ bodily make up (i.e. whether or not they are obese). These factors also include diver fitness, including any medical conditions, such as a hole in the heart, hydration, hard exercise on the dive or afterwards and how cold the water is.
