20. There are a number of causes of vitamin D deficiency

Sat Dec 21, 2013, 12:21 PM

Dec 2013

Malabsorption (common with Crohn's, Celiac Disease, ulcerative Colitis, etc)

Hypoparathyroidism (common in kidney disease)

Sunlight intolerance (lupus, sunlight allergy)

Dark skin tone

Etc

It's also painful.

I found this out the old-fashioned way: I'm deficient, and it's due to malabsorption, sunlight allergy and kidney disease Not my dx; my doctor's and I take Rx supplementation.
