Diabetes is when the body has too much glucose (sugar) due to a disruption in insulin that comes from the pancreas. Insulin regulates the glucose, which is a major source of energy for cells that make up muscles and other tissues, and also feeds brain function. There are different types of diabetes – type 1 (most serious and chronic), type 2 (also chronic), prediabetes (abnormal blood sugar levels), and gestational (affects women who are pregnant). With careful management of medication, diet and exercise, diabetes can be controlled.
