To begin to answer that question, we must define osteopenia. Osteopenia is the thinning of bone mass. While this decrease in bone mass is not usually considered severe, it is considered a very serious risk factor for the development of osteoporosis. Osteopenia is commonly seen in people over age 50 that have lower than average bone density but do not have osteoporosis. The diagnostic difference between osteopenia and osteoporosis is the measure of bone mineral density. Osteoporosis, the fragile bone disease, is characterized by a loss of bone mass caused by a deficiency in calcium, vitamin D, magnesium and other vitamins and minerals.
