AMBULATORY CARE:
Vitamin D deficiency
is a low level of vitamin D in your body. Vitamin D helps your body absorb calcium from foods. Your body makes vitamin D when your skin is exposed to sunlight. You can also get vitamin D from certain foods. Most of the vitamin D in your body comes from sunlight exposure.
Common symptoms include the following:
Low levels of vitamin D can lead to weak and brittle bones that are more likely to fracture. You may not have any signs and symptoms, or you may have any of the following:
- Bone pain or discomfort in your lower back, pelvis, or legs
- Muscle aches and weakness

Call your doctor or dietitian if:

Treatment for vitamin D deficiency
includes high doses of vitamin D for 8 to 12 weeks to increase your levels. Your levels will then be rechecked. If your levels are still low, you will need to take vitamin D supplements for another 8 weeks. After your levels have gone back to normal, you may need to continue to take a vitamin D supplement.
