What to know about vitamin D deficiency in postmenopausal women

Vitamin D helps the body use calcium and supports bone and muscle function. After menopause, changes in bone metabolism can make a review of bone-health risks useful. Limited outdoor exposure, low dietary intake, digestive conditions, kidney or liver problems, and some medicines can contribute to low vitamin D.

Possible signs include bone discomfort, muscle weakness, or repeated falls, although these findings are not specific. A clinician may review fracture history, medicines, diet, mobility, and other causes before recommending a blood test or treatment.

Discuss vitamin D with your clinician if you have risk factors, persistent aches, weakness, or a history of falls or fractures. Include dietary sources, suitable weight-bearing activity, and strength or balance work when safe for you. Follow local sun-safety advice rather than pursuing unprotected exposure.

Use supplements only as advised, and tell the clinician about calcium products and every other medicine or supplement. Too much vitamin D can be harmful. The [Vitamin D Deficiency](/conditions/vitamin-d-deficiency/) page provides general information.

Arrange prompt review for new bone pain, increasing weakness, balance problems, or repeated falls. Seek urgent care after a significant fall, severe pain with inability to use a limb, sudden weakness, confusion, or breathing difficulty. Do not wait for a routine vitamin test after a serious injury.

Ask whether vitamin D testing is appropriate, how your fracture and fall risks should be assessed, and which supplement or activity plan fits your health. Ask whether medicines, calcium intake, or another condition needs review.
