According to the NHS, revealing signs of high blood sugar are:
- Increased thirst and dry mouth
- Need to urinate often
- Blurry vision

To avoid high blood sugar, the most important thing is to follow your food carefully, especially measuring the amount of sugar and carbohydrates in your food.
If you have been prescribed insulin by your doctor, you should take this exactly as directed, reduce the risk of hyperglycaemia or become "high".
However, other lifestyle factors can also affect your blood sugar level, and by dealing with these risks you can avoid dangerously high blood sugar rises.
By testing your blood sugar regularly, you can detect high blood sugar before it reaches dangerously high levels, which may require medical attention.
