i gained 40+kg in the month following commencement of depo-provera last year 2012/13. This excess weight is now impossible to lose, proven over last 5 months since marriage. What can i do to recover my normal health and normal weight? gastric surgery is not an option. I am now an unhealthy weight and extremely anxious with respect to starting a family. I am also very concerned about bone density loss as i have long-standing upper spine issues.
