You may wonder what exactly leads to this health condition. The primary reason is the diabetes mellitus; if you don’t have one, you won’t most probably face hyperglycemia. There are acute and chronic forms. The second one is related to diabetes. In most cases, chronic form takes place. Healthcare professionals also name the third type which is an intermittent hyperglycemia. It can be experienced at the pre-diabetic stages. If hyperglycemia appears before diabetes, the person is most likely to face the second trouble as well.
