Here are some clearer warnings about hyperglycemia.

Hyperglycemia means when your blood glucose level rockets in your body to become dangerously high!

Hyperglycemia is a common circumstance of diabetes, but through medication such as measured doese of insulin, exercise and careful meal planning, you can keep your blood glucose level from going too high. Doing this will enable you have a healthier lifestyle and decrease dangerous side effects that could even lead to a painful death.

Keeping your blood glucose levels in the recommended ranges throughout the day will help you avoid future complications of diabetes. Here are some examples:

Eye damage leading to possible blindness

Stroke

Cardiac arrest (heart attack) or other cardiovascular complications

Kidney damage

Nerve damage, particularly in the legs affected by the vascular system ...leading to...

...Diabetic ulcers in your legs, particularly the lower areas (near your ankles) which will lead to wounds taking a longer time to heal - during which time could attract bacteria to enter the ulcer, thus causing cellulitis or even sepsis, both of which could killers if not treated quickly in hospital using anbiotics by IV.

However, if you constantly maintain your blood glucose levels, thus avoiding hyperglycemia, you then reduce your risk of all these complications that could otherwise put you in hospital! Long term hyperglycemia can cause painful leg ulcers.

I implore those with either types of diabetes to be wary of hyperglycemia. Buy a book on diabetes to help you learn what foods are good and what food and drink you should avoid. Some books even have useful recipes.
