Diabetes, or diabetes mellitus, is a disease that is associated with the body’s inability to regulate and normalize blood glucose levels due to the inability of the pancreas to produce enough of a hormone called insulin. Insulin’s main function is to turn blood glucose into energy for the body to use, and insulin production levels vary by affected individuals. Diabetes is categorized into different conditions or types, each condition having its own underlying causes. Preventable diabetes conditions include prediabetes and gestational diabetes, whereas chronic conditions include type 1 and type 2 diabetes. All types, if left uncontrolled, can cause an excess of sugar in the blood that may lead to serious health complications in the future, such as heart disease, stroke, nerve damage, complications of the eye (glaucoma, cataracts, etc.), kidney disease, and high blood pressure.
