Divers can lessen their chances of getting decompression sickness by minimizing pre and post-dive activity and exertion, do slow ascents (no faster than 30'/minute), stay well within no-stop time limits, and always do safety stops including deeper safety stops.
the farther divers go below the surface of the ocean, the higher the pressure acting on their body gets.
This increased pressure causes the nitrogen in the blood to compress (gases are compressible). If the diver ascends to quickly, the nitrogen in the blood expands to quickly, and can not be absorbed by the body. This causes all sorts of medical issues, mostly stemming from the oxygen supply to the brain.
The answer is more involved than above. The pressure during the dive from the water pressure does not cause the inert gas (i.e. nitrogen if air is used during the dive) to be compressed since it is not in a free gas state when it is in the blood during the dive. Instead, the pressure from the dive causes the partial pressure of the inert gas to increase. Since an inert gas by definition does not do anything other than "sit there" as compared to oxygen that is metabolized or used, it will continue to accumulate in the tissues since there partial pressure of the nitrogen being breathed underwater is greater than the partial pressure of the nitrogen that is in the tissues. As the diver surfaces, the surrounding water pressure decreases. This results in there being more gas in the tissues (from the dive) as compared to the surrounding atmospheric pressure at the surface. If the dive was "too long" and/or did not adequately decompress, bubbles can result from the gas built up during the dive. Bubbles then cause pain by putting pressure on the nerves in the body and they can also interfere with the central nervous system and even cause paralysis if not treated. It is not really an oxygen supply issue to the brain as stated in the original answer.
When divers are underwater, they breathe air that is at a higher pressure than normal. The deeper you go, the more pressure. This can force nitrogen gas from the air into your bloodstream. When a diver comes back to the surface, pressure is reduced, and the nitrogen comes out of the blood and forms bubbles, typically at body joints. This is very painful and potentially life threatening. Divers "decompress" gradually, allowing nitrogen to be expelled from the blood and from the body safely.

What decompression sickness do scuba divers suffer from?
It is called "The Bends"
Who gets decompression sickness?
Scuba divers who surface too quickly after a deep dive are prone to decompression sickness.
The bends also known as decompression sickness is as painful condidtion that occurs in scuba divers who asend too quickly.?
If you wanted to know if this is true, then yes, this is the Bends.
What is it called when you resurface to fast scuba diving?
Its called'The bends'
Why do scuba divers need to be depressurised?
That only occurs when divers remain under longer than the recommended no-decompression limits. But it is done to allow the body to slowly rid itself of nitrogen that has built up in the bloodstream due to breathing pressurized air at depth. If it isn't done, the bubbles pop in a blood and cause decompression sickness, which is very dangerous.
What is meant by the sick term divers diseases?
Scuba diver's diseases include decompression sickness, pulmonary embolus or emboli, oxygen toxicity, nitrogen narcosis, and other afflictions associated with scuba diving, working under different pressures, at sea, or underwater.
What is the collective noun of scuba divers?
The collective noun is a bubble of scuba divers.
How can pure oxygen be used for the benefit of mankind?
Pure oxygen can be used in medical treatments to support patients with respiratory issues, in scuba diving to prevent decompression sickness, and in industrial processes like steelmaking and water treatment.
When can I Scuba dive after embolism?
withOut knowing more details than "EMBOLISM"* Pulmonary embolism?* Brain embolism?* Air embolism - caused by an air bubble; usually from decompression sickness in divers?* Thromboembolism - an embolism caused by a blood clot ?you're best bet is to talk to your doctor
Why it is dangerous for scuba diver to more up rapidly into the water surface?
A scuba diver should not ascend rapidly, because the nitrogen in their bloodstream will lose pressure and create bubbles in the bloodstream. This will cause decompression sickness, which can be fatal.
Who uses a scuba-suit?
Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.
Who can get bends?
scuba divers
