In children it causes rickets; in adults it causes osteomalacia (bone pain, proximal muscle weakness,Looser zones) and contributes to osteoporosis/falls/fractures. Causes: limited sunlight, dark skin, low dietary intake, malabsorption, chronic kidney disease. Diagnosis by serum 25-OH vitamin-D; treatment: vitamin-D supplementation plus calcium.
