Maybe I worry too much, but I want to know how osteopenia will affect my overall health.?

Progressive. Osteopenia is a slight decrease in bone mass. This can progress to osteoporosis if not prevented early. Osteoporosis is significant bone mass decrease and is associated with an increase in fracture risk, such as the spine or the hip.
