What Causes the Bends?

The bends is another term for decompression sickness, which can occur to SCUBA divers. It is caused by breathing in compressed gasses, such as nitrogen, that cannot be processed by the body. The bends can be fatal, but fortunately it is rare. You can find more information here: http://www.emedicinehealth.com/decompression_syndromes_the_bends/article_em.htm#The%20Bends%20Overview
