If your blood glucose stays over 180, called hyperglycemia, you don't have enough insulin in your body.
Watch for these signs:
- Feeling very thirsty and tired
- Blurry vision
- Going to the bathroom often
- Feeling sick to your stomach
If you notice these symptoms, discuss them with your doctor because elevated glucose levels lead to complications such as blindness and nerve damage as well as life-threatening illnesses like heart and kidney disease. To get your sugars in check, you may need to adjust your diet and exercise regimen or your medication.
