Also known as low blood sugar. It occurs when blood glucose levels drop to below 4 mmol/l. This can happen if a person with diabetes has taken too much insulin or has exercised more than usual. Symptoms of hypoglycaemia include dizziness, shakiness, rapid heartbeat, sudden hunger, cold or clammy skin, fuzzy vision, confusion, mood changes, and tingling or numbness in the hands, arms, tongue, or lips. Hypoglycaemia can occur even while using an insulin pump and, if left untreated, can lead to unconsciousness and diabetic coma.
Pre-Diabetes – blood glucose (sugar) levels higher than normal but not high enough to be called diabetes. People with pre-diabetes may or may not develop diabetes. Other names for pre-diabetes are impaired glucose tolerance, impaired fasting glucose, borderline, subclinical, chemical, or latent diabetes.
