Like rickets in children or osteoporosis in the adults. Less vitamin D in your body can also play a vital role in development of non-alcoholic fatty liver disease.
It is often becomes very difficult to find that whether a newborn or an adult is suffering from Hypovitaminosis D. However, a swift diagnosis of vitamin D deficiency can be made if someone has a sweaty forehead.

So taking a test of this profile, is considered as a good reflection of how much of vitamin D the patient has absorbed from daily diet and from the rays of the sun.
Levels of this vitamin are expressed in nmol/L (nanomoles/liter) or ng/mL (nanograms/milliliter).
Doctors can also ask the patient for undergoing a special bone density scan, if the patient is suffering from brittle bones or symptoms of osteoporosis.
