https://medlineplus.gov/vitaminddeficiency.htmlWhat causes vitamin D deficiency?
You can become deficient in vitamin D for different reasons:
You don't get enough vitamin D in your diet
You don't absorb enough vitamin D from food (a malabsorption problem)
You don't get enough exposure to sunlight.
Your liver or kidneys cannot convert vitamin D to its active form in the body.
You take medicines that interfere with your body's ability to convert or absorb vitamin D
Who is at risk of vitamin D deficiency?
Some people are at higher risk of vitamin D deficiency:
Breastfed infants, because human milk is a poor source of vitamin D. If you are breastfeeding, give your infant a supplement of 400 IU of vitamin D every day.
Older adults, because your skin doesn't make vitamin D when exposed to sunlight as efficiently as when you were young, and your kidneys are less able to convert vitamin D to its active form.
People with dark skin, which has less ability to produce vitamin D from the sun.
People with disorders such as Crohn's disease or celiac disease who don't handle fat properly, because vitamin D needs fat to be absorbed.
People who have obesity, because their body fat binds to some vitamin D and prevents it from getting into the blood.
People who have had gastric bypass surgery
People with osteoporosis
People with chronic kidney or liver disease.
People with hyperparathyroidism (too much of a hormone that controls the body's calcium level)
People with sarcoidosis, tuberculosis, histoplasmosis, or other granulomatous disease (disease with granulomas, collections of cells caused by chronic inflammation)
People with some lymphomas, a type of cancer.
People who take medicines that affect vitamin D metabolism, such as cholestyramine (a cholesterol drug), anti-seizure drugs, glucocorticoids, antifungal drugs, and HIV/AIDS medicines.
