Of near miss events, obstetrical fistulae (OF), including vesicovaginal and rectovaginal fistulae, remain one of the most serious and tragic. Although corrective surgery is possible it is often not available and OF is considered completely preventable. If repaired, subsequent pregnancies will require cesarian section. While unusual in developed countries, it is estimated that up to 100,000 cases occur every year in the world, and that about 2 million women are currently living with this condition, with the highest incidence occurring in Africa and parts of Asia. OF results from prolonged obstructed labor without intervention, when continued pressure from the fetus in the birth canal restricts blood supply to the surrounding tissues, with eventual fetal death, necrosis and expulsion. The damaged pelvic organs then develop a connection (fistula) allowing urine or feces, or both, to be discharged through the vagina with associated urinary and fecal incontinence, vaginal stenosis, nerve damage and infertility. Severe social and mental consequences are also likely to follow, with shunning of the women. Aprt from lack of access to care, causes include young age, and malnourishment. The UNFPA has made prevention of OF a priority and is the lead agency in the Campaign to End Fistula, which issues annual reports and the United Nations observes May 23 as the International Day to End Obstetric Fistula every year. Prevention includes discouraging teenage pregnancy and child marriage, adeaquate nutrition, and access to skilled care, including caesarian section.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
