Women and Scuba Diving. Part 3 ? kccdc blog

As far as returning to the water after giving birth, a woman can resume diving when she is back to her normal health, strength and endurance level. Ultimately, this decision needs to be left up to a physician after a full physical examination and medical clearance permit strenuous activity.

Scuba Diving and Endometriosis
What exactly is Endometriosis and is there any cause for concern relating to diving? Endometriosis is when tissue containing endometrial cells occurs abnormally in various locations outside the uterus, but most commonly inside the uterus. Endometrial cells have appeared in the lungs, stomach and other unlikely areas of the anatomy (in severe cases). During menstruation this abnormally occurring endometrial tissue, like the lining of the uterus, goes through what is referred to as cyclic bleeding. The blood within the endometrial tissue cannot drain to the outside of the body, thus forming pockets that collect blood in the surrounding tissue, causing severe pain and discomfort. Because Endometriosis is known to cause increased bleeding, cramping, as well as a longer menstrual flow, diving may not be in a woman?s best interest when she experiences these symptoms. All divers (male and female) should only conduct dives in the utmost optimal state of health.

Scuba Diving with breast implants
There have been experiments conducted with silicone, saline, and silicone/saline filled breast implants. The results of the experiments showed that there was a minimal increase in bubble size in both saline and silicone gel implants. Fluctuations in results varied on the depth and duration of the dives conducted. The saline-filled implant resulted in the smallest volume change because nitrogen is less soluble in saline than in silicone. The silicone/saline filled implant showed the greatest volume change. Bubble formation in the silicone implant led to a small volume increase, however, not enough to damage the implants or any of the surrounding tissue. If gas bubbles are to form in the implant, they dissolve over time. After a sufficient amount of time has passed after undergoing breast augmentation surgery, the diver can resume diving once all normal activities have been resumed and there is no danger of infection.

Women diving with breast implants need not worry, as implants are not known to cause significant gas absorption or changes in size and are not a dissension for participation in recreational scuba diving. Women diving with implants should take special precautions and avoid using BCD?s with constrictive chest straps that can place undue pressure on the seams and possibly cause risk of rupture. With regard to buoyancy issues, breast implants filled with saline are neutrally buoyant whereas silicone implants are heavier than water and may alter buoyancy and trim under water, particularly if the implants are large. This offset in buoyancy can be adjusted with proper weight considerations, which can help overcome these difficulties.

In summary, there is no conclusive evidence, which points to women being more susceptible to DCS. However, it is highly recommended that women abstain from scuba diving throughout the various stages of pregnancy. Until concrete study results are reached, it is quite simply not worth the risk. Apart from pregnancy, there are no major physical repercussions that would prevent women from taking up the sport of recreational scuba diving. Diving is a wonderful, peaceful and safe sport that can be enjoyed by both men and women alike.
