Symptoms of vitamin D deficiency in females

Vitamin D helps the body absorb calcium and supports muscles and bones. Low levels can be associated with aching bones, muscle weakness or tiredness. These symptoms are common in many other conditions, so they cannot confirm deficiency on their own. Limited sun exposure, darker skin, covering most of the skin, digestive absorption problems and some medicines can increase the chance of low levels. Vitamin D deficiency is diagnosed with a blood test and an assessment of bone health.

Arrange a medical review if tiredness, weakness or bone discomfort continues, especially if you have risk factors. Do not start high-dose supplements without advice; the right product and dose depend on your health and test results. A clinician may discuss food sources, safe sunlight habits and supplementation.

Seek prompt medical care for sudden severe bone pain, inability to bear weight, a suspected fracture, marked muscle weakness, or new difficulty walking. Recurrent fractures or pain after a small injury also deserve assessment, including for a [Stress Fracture](/conditions/stress-fracture/). Emergency help is needed for severe weakness with breathing difficulty, fainting or confusion.

Ask whether a vitamin D blood test is appropriate, whether calcium or other tests are needed, and which symptoms could have another cause. Tell the clinician about pregnancy, breastfeeding, digestive conditions, kidney or liver problems, and all supplements or medicines you take.
