what happens if you have low blood sugar levels
If your blood sugar drops too low, you can have a low blood sugar reaction, called hypoglycemia. A low blood sugar reaction can come on fast. It is caused by taking too much insulin, missing a meal, delaying a meal, exercising too much, or drinking too much alcohol.hat is why it is very important to test your blood and keep taking your medicine (insulin or diabetes pills) when you have an infection or are sick. Your blood sugar may be too high if you are very thirsty and tired, have blurry vision, are losing weight fast, and have to go to the bathroom often.
