Indicators of Vitamin D Deficiency

Vitamin D deficiency, known as "sunshine vitamin," may not cause obvious symptoms in most cases. However, it leads to bone and muscle problems when severely and chronically deficient, resulting in rickets and osteomalacia, along with pain, weakness, and an increased risk of fractures and falls. Causes include limited sun exposure, an inadequate diet, illnesses that affect the absorption or conversion of the vitamin, obesity, and medications that accelerate its breakdown. Diagnosis involves blood tests, especially for individuals with risk factors. Treatment typically involves supplements (50,000 IU weekly for 8 weeks or 6,000 IU daily), along with improved nutrition and moderate sun exposure. Prevention requires consuming 600 to 800 IU daily, depending on age, considering health status and sun exposure levels.
