Re: 25 years old just diagnosed with osteoporosis
Anabolic = building or creating new, Catabolic = breaking down. Bisphosphonates work my inhibiting osteoblasts (which break down bone). However research is emerging that in the long run this may follow on to a decrease in osteoclast (which build new bone) activity. So bisphosphonates are a catabolic aid. New research is going into anabolic therapy, to boost osteoclast activity instead.
At least this is how I understand it after a few days of reading!
