Vitamin D Deficiency May be Associated With Diabetic Retinopathy

Diabetic retinopathy occurs when high blood sugar levels damage the blood vessels of the retina. A recent study suggests that vitamin D deficiency may be associated with diabetic retinopathy.


For their analysis, researchers looked at data from 14 observational studies that included 10,007 people with diabetes age 18 and older from a range of countries. All of the participants were screened for both vitamin D deficiency and diabetic retinopathy.


After analyzing the data, the researchers found that people with diabetic retinopathy had significantly lower vitamin D levels than those who did not. They determined that there is a significant association between diabetic retinopathy and vitamin D deficiency.


Researchers from Yale University School of Medicine led the study. It was published in the April 2017 issue of the Canadian Journal of Ophthalmology.


Previous studies have associated vitamin D with improved lipid profiles in diabetics, lower risk of asthma and allergies in children, reducing the risk of skin damage, reducing the risk of osteoporosis, combating diabetes, lower risk of cognitive decline, and improving age-related macular degeneration.


Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
