Re: Secondary Amenorrhea
The longer you go without periods, the greater your odds of developing osteoporosis. I'm sure it depends on the individual how long without periods is serious enough to develop a problem and how long you were starving your body before losing your periods. I lost my periods for just over a year, and I'm not sure how much damage did or did not result as I never did have a bone scan afterwards. Hopefully, it was not too much damage. I haven't had bone problems, but that doesn't mean they're not there. For a long time, I was without health insurance and so couldn't get checked and now I'm just a bit scared to although I'll look into it after my baby is born.
Your periods will return once you begin eating well and gain some weight. For me, they returned after about 3 months at the weight I was when I lost them. This was also pretty close to the weight I was when I began menstruating (for some women, periods correspond more with a specific weight and for others, it's more healthy eating habits and no longer starving your body). Of course, at this point, I was in recovery and gaining weight and no longer depriving my body of nutrients so it could be either the eating habits or the weight. But for me, it was interesting that I started menstruating at this specific weight, lost my periods once I went below the same weight, and got them back after getting back to that weight again.
