Why do so many medical professionals have weight loss surgery?

This was posted on obesity help today;
Just curious to see how many had some kind of medical background, education or experience at the time of their surgery .. I have a hunch a disproportionately high % of WLSers do, vs. the general population. If so, that would seem to indicate that it's the medically-savier or more confident MO or SO person who goes through with WLS .. or it could be the case that medicos have better insurance or greater means to cash pay .. (?) So if you have a medical field background, please speak up ..

I can attest that at least for this medico, I certainly DID NOT have a better insurance through ANY of the clinics, hospitals, nursing homes, that I have worked for. I tried for over 5 years to get approved. During that time, I have two jobs for the most part and tried with each insurance, changing insurance at both employers during each open enrollment till I had exhaused all options, I changed jobs a few times too and several had exclusions for weight loss surgery(including Boulder Community Hospital), fertility treatments, etc written into their policy so there was no even trying with them. I have worked for 3 catholic hospitals that won't pay for any type of birth control or family planning. I had NO options for maternity leave at the hospital where I worked when I had my daughter Lilith except for the goverment granted family unpaid medical leave. I worked almost EVERY DAY my last trimester (18 days in a row without a day off at one point and most pay periods with only one day off) till I was 9 months and 2 weeks along. I was getting calls by my unit manager two weeks after having her (via c-section) at their hospital, trying to force me to come back to work 12 hour night shifts! I tried with my husbands insurance (he worked for a energy company) and was approved in less than 2 weeks, no 6 months x2 doctor supervised diets, no food diaries, heck no long winded letter from my dr., just my health history and her recommendation. I cried. He was approved after 3 weeks for his as he had to have more preop testing for is sleep apnea and blood pressure. I think the reason so many medicos are having this surgery is because we are so very busy taking care of everyone else at work and at home that we neglect ourselves. I have know several nurses that have neglected themselves to the point of dying from heart disease, cancers, etc. I think we are statistically involved in more abusive or neglectful relationships and have a, "we can save them" mind set about everyone else but ourselves. I think mothers do this too, always put themselves last. What I have learned is, if you don't take care of yourself first (like putting the oxygen on yourself before your children on an airplane), you can't effectivly take care of anyone else. So you really OWE it to your children, family, and friends to take care of yourself, emotionally as well as physically! I am working on this and for me, having this surgery is a first step.
