that is not what osteoporosis means....in fact it is the opposite.Osteoporosis, which means"porous bones,"causes bones to become weak and brittle — so brittle that even mild stresses like bending over, lifting a vacuum cleaner or coughing can cause a fracture. In most cases, bones weaken when you have low levels of calcium, phosphorus and other minerals in your bones.A common result of osteoporosis is fractures — most of them in the spine, hip or wrist.
