zaileigh, alendronate works by attaching to your bone. When the cells that remove fissured or otherwise damaged bone try to attach they and the alendronate are destroyed. What happens is that for some reason (usually lower estradiol levels) we have more cells that destroy bone than cells that build bone. Our bones can't rebuild fast enough to keep up with the removal. The bone we preserve is not as strong as it would be with a medication like Forteo or Tymlos that increase removal but increase replacement to a greater degree.
The many endocrinologists are recommending starting to address bone loss with a bone builder and following it with a drug like alendronate.
