How do you feel?

High blood glucose (hyperglycemia) occurs when there is too much sugar in the blood, above 13.3mmol/L (240mg/dL), and may be caused by insufficient insulin, overeating, inactivity, illness, stress, or a combination of these factors. Can lead to the buildup of ketones (chemicals your body makes when insulin levels are very low and excessive amounts of fat are being burned). Ketone buildup over several hours can lead to serious illness and coma, a condition called ketoacidosis. Signs of ketoacidosis include vomiting, weakness, rapid breathing, and a sweet breath odor. High blood glucose levels can also lead to a hyperglycemic hyperosmolar nonketotic coma, where blood glucose is 33.3 to 44.4mmol/L (600 to 800mg/dL), and occurs most often in people over 60.
