These are two symptoms of low blood sugar or hypoglycemia which is especially common in type 1 diabetes patients. If it falls below 70 and left untreated, it could fall lower and cause you to faint. If your blood sugar is below 70, eat a couple of tablespoons of raisins or take half a cup of orange juice. Monitor and ensure that your blood sugar rises above 70. If you still feel dizziness or confusion, speak to your doctor.
These symptoms suggest that your blood sugar is far too high or also know as a state of hyperglycemia. It can lead to severe complications such as heart disease, kidney damage and nerve damage. You can restore your blood sugar levels to normal by exercising, eating a controlled diet for diabetics and taking your medication regularly. If left untreated, high blood sugar can cause several complications including diabetic coma.
