M83: Adult osteomalacia

M83.5: Other drug-induced osteomalacia in adults

Other drug-induced osteomalacia in adults, coded as M83.5, refers to a condition where the bones become soft and weak due to prolonged use of certain medications. This often results in bone pain, muscle weakness, and an increased tendency to fracture. The cause of this condition can be traced back to a lowered vitamin D levels in the body, which is often an adverse effect of certain medications, as vitamin D is crucial for the absorption of calcium and phosphate, necessary for strong and healthy bones. Osteomalacia is different from osteoporosis in that the bones are weak due to a lack of bone mineralization, rather than a decrease in the total amount of bone. The onset of this condition can be gradual and symptoms may not be evident until the disease has advanced significantly.
