Normally I consider myself pretty well-educated on matters of the reproductive system, but I confess this is a bit over my head. I wonder if anyone here can help me out?
Basically, I have PCOS and historically had very irregular/absent menses. At one point I had 3yrs without a period. I was very HWP at the time and running many miles per week. My primary care doctor told me about the "female athlete triad" and said that I was at risk for low bone density if I did not get regular with my menses.
Ok, so I went on Yasmin BCP for 2yrs, during which I had monthly withdrawl bleeds. When I wanted to come off it and try a Paragard IUD, my new primary care doctor did a bone scan, so we would have a "starting point" for any osteopenia. The bone scan didn't look at any specific areas - it just went over my hips/spine and averaged to come up with a percentage. Apparently, at the time I was on the very high end of normal for bone density.
I had the Paragard IUD for just over a year, very irregular/abnormal menses. About 9 months ago, I got the Mirena IUD. I've had two menses during my time with the Mirena, and one was very light.
.....and now I have a stress fracture. From running. I'm going to have to take a break from running for a while and wear an offloading boot to let the fracture heal. My question is - I didn't really do anything that would cause a stress fracture (suddenly increasing running mileage, change shoes) so could I have become osteopenic in the past 2yrs since I've been off HBC? Does the Mirena IUD have any effect on increasing or decreasing bone density? Should I consider asking for a full body bone scan to assess whether the "female athlete triad" has returned?
I know from my labwork during the PCOS diagnosis that I have low normal estrogen and progesterone levels and somewhat high testosterone/sex binding immunoglobin hormone. I also have high total cholesterol and low LDL.
TIA! This community is awesome. :-)
