So many of my patients who have insulin resistance, type 1 or type 2 diabetes with hyperglycemia and/or obesity have vitamin D or vitamin B12 deficiency. Often they have never had their levels checked or, if they have, were diagnosed with either or both vitamin D deficiency and vitamin B12 deficiency and do not take their prescribed vitamins. Why?

Female, 67 years of age, type 2 diabetes, class 2 diabetes, depression, hyperlipidemia, vitamin D deficiency plus more. Her A1C is 6.8% and her lipids are within goal. Her random glucose 2 hours after eating cookies was 118 today. Her glucose lowering meds are Trulicity, metformin, and Jardiance. She takes them as prescribed. Her endocrinologist recommended she meet with me. She refused until he recommended she see me the same day she was coming in to see another health care provider for her monthly infusion for another disease process to make getting here easier.

Concerned about the extreme weather disasters we have had and those predicted, I reached out to Carol Atkinson, Director of Insulin for Life, a trusted organization, to see how we could help. She was so busy putting packages together for people who have diabetes, she quickly told me the story of Wharton, Texas. It was Labor Day weekend. Hurricane Harvey had just hit and it hit Wharton, Texas hard. They were in need of insulin.
