Diabetes is a disease in which the body doesn't produce or properly use the hormone insulin. Insulin allows glucose (converted from carbohydrates) into the cells for energy. There are three types of diabetes, Type 1, Type 2, and gestational diabetes. If you have Type I diabetes your body does not make insulin. If you have Type 2 diabetes your body does not make or use insulin well. If you have gestational diabetes only during pregnancy and typically goes away after the pregnancy.
Without enough insulin, glucose cannot enter into the cells and so builds up in the bloodstream. High blood glucose levels lead to frequent urination, extreme thirst, and tiredness.
