Can you have low vitamin D and normal calcium levels?

So, vitamin D deficiency is characterized biochemically by either a normal, or low-normal, serum calcium with a low-normal, or low-fasting, serum phosphorus and an elevated serum PTH.

Is Vitamin D Deficiency the same as calcium deficiency?

Vitamin D plays a crucial role in calcium absorption and bone metabolism. Many older people who are diagnosed with bone loss believe they need to take more calcium. However, they may be deficient in vitamin D as well. Low bone mineral density is an indication that your bones have lost calcium and other minerals.

Can vitamin D affect calcium levels?

When vitamin D level is low, the absorption of calcium in the intestines becomes less, which then causes the level of calcium in the blood to go down. As a consequence the parathyroid glands become more active and produce more PTH that causes calcium to come out of the bones, therefore weakening the bones.

Does a normal blood test show vitamin D deficiency?

The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. A level of 20 nanograms/milliliter to 50 ng/mL is considered adequate for healthy people. A level less than 12 ng/mL indicates vitamin D deficiency.

What is normal vitamin D level?

The normal range of vitamin D is measured as nanograms per milliliter (ng/mL). Many experts recommend a level between 20 and 40 ng/mL. Others recommend a level between 30 and 50 ng/mL. The examples above are common measurements for results of these tests.

What is the similarity between vitamin D and calcium?

Calcium and vitamin D work together to protect your bones—calcium helps build and maintain bones, while vitamin D helps your body effectively absorb calcium. So even if you’re taking in enough calcium, it could be going to waste if you’re deficient in vitamin D.

Is vitamin D deficiency irreversible?

Severe vitamin D deficiency can leads to multiple musculoskeletal disorders and if not treated early, this can leads to irreversible deformity.
