Q

what is ketoacidosis

A

a serious complication of diabetes that occurs when the body produces high levels of ketones. Ketoacidosis results from the body not having enough insulin to be used for energy. Without insulin, the body breaks down fat to get the energy it needs. This can be dangerous because it causes a build-up of acids in the body.

Q

what is hypersomolar hyperglycaemia syndrome (HHS)

A
  • a complication of diabetes often triggered by infection or illness
  • involves extremely high blood glucose levels w.o significant presence of ketones
