Will my sister have osteoporosis &or have osteoarthritis? shes 40s.if my mom has it .shes smoker nonactive, diet poor&has joint bone pain right side.

Probably yes: Our health is determined by a combination of genetics ; lifestyle factors. Since your mom has it you are both at increased risk but a healthy diet ; lifestyle can still minimize that risk. Being sedentary, smoking ; poor diet all increase risk so the odds are quite high she will get these- she may already have them! see http://bit.Ly/1a48ofs ; http://bit.Ly/1a2dbdw.
