Why is a perso'sn vitamin D low

Hello Anonymous,

Welcome to EmpowHER.

Not getting enough Vitamin D over time can cause a low level. Limited exposure to the sun is another.

As people age, their kidneys are less able to convert vitamin D to its active form, thus increasing their risk of vitamin D deficiency.

Certain medical problems, including Crohn's disease, cystic fibrosis, and celiac disease, can affect the intestine's ability to absorb vitamin D from the food.

Vitamin D is extracted from the blood by fat cells, altering its release into the circulation. People with a body mass index of 30 or greater often have low blood levels of vitamin D.
