M83: Adult osteomalacia

M83.9: Adult osteomalacia, unspecified

Adult osteomalacia, sometimes referred to as "soft bones," is a condition characterized by a deficiency or impaired metabolism of vitamin D, phosphate, or calcium. This leads to the softening of the bones, increasing the risk of fractures and causing symptoms such as bone pain and muscle weakness. In many cases, the onset of the disease is gradual and an individual may not notice any symptoms until the condition has progressed substantially. Adult osteomalacia affects the skeletal system, and is different from the childhood condition known as rickets, which also results from a deficiency in vitamin D. Both conditions, however, share the common characteristic of inadequate mineralization of the bone tissue. Causes of adult osteomalacia can include insufficient exposure to sunlight (a primary source of vitamin D), certain dietary deficiencies, malabsorption issues, and certain surgeries or medications.
