Osteomalacia refers to a marked softening of your bones, most often caused by severe vitamin D deficiency. The softened bones of children and young adults with osteomalacia can lead to bowing during growth, especially in weight-bearing bones of the legs. Osteomalacia in older adults can lead to fractures.
Treatment for osteomalacia involves providing enough vitamin D and calcium, both required to harden and strengthen bones, and treating disorders that might cause the condition.
When osteomalacia is in its early stages, you might not have symptoms, although signs of osteomalacia might show on an X-ray or other diagnostic tests. As osteomalacia progresses, you might develop bone pain and muscle weakness.
The dull, aching pain associated with osteomalacia most commonly affects the lower back, pelvis, hips, legs and ribs. The pain might be worse at night or when you put pressure on the bones. The pain is rarely relieved completely by rest.
Decreased muscle tone and leg weakness can cause a waddling gait and make walking slower and more difficult.
