Hyperglycaemia or a “hyper” means your blood glucose level is continuously higher than normal. This usually applies to undiagnosed or untreated diabetes.
The opposite is Hypoglycaemia or a “hypo”, when the blood glucose level is below what is normal, and your body doesn’t have enough energy to be active.
Being Hypo is common in people with diabetes, especially in those who require insulin injections to help control their glucose levels. It usually happens when they inject too much insulin, miss a meal, drink too much alcohol or exercise too much.
The usual warning signs are:
• feeling hungry
• trembling or shakiness
• sweating; tiredness
• blurred vision
• going pale
• fast pulse or palpitations
• tingling lips; irritability
• difficulty concentrating
• disorderly or irrational behaviour, which may be mistaken for drunkenness
• loss of consciousness.
Someone who has a hypo needs to correct their blood glucose levels by eating or drinking food that contains sugar (or taking glucose tablets). Food or drink such as chocolate and milk which are high in fat are no good, because they don’t have enough sugar in them.[clear-line]
