A patient was admitted to the critical care unit of a hospital after their lab values came back as abnormal. PTH values were very low, calcium levels were very high, and Vit D 25(OH) levels were extremely high. It is to be noted that the patient has recently had a change in diet and lifestyle, and the patient claimed historically having a very bad diet.

-Addison’s Disease
-Primary Hypoparathyroidism
-Grave’s disease
