Vitamin D deficiency can lead to a variety of symptoms, many of which are subtle at first. Common signs include fatigue, muscle weakness, joint pain, mood changes (especially depression), and frequent illness due to a weakened immune system. In severe cases, it may cause bone pain or conditions like rickets in children and osteomalacia in adults. Low vitamin D levels are often caused by limited sun exposure, poor diet, or medical conditions affecting absorption. A blood test can confirm deficiency, and treatment typically involves supplements and lifestyle changes.
