Causes of high blood sugar

One of the best ways for you to control your sugar levels is to know what causes your sugar level to go up. By knowing the causes, you can take steps to stay away from or lessen the causes. You can’t fix the problem if you don’t know that you have one.

Causes of high blood sugar include:
  • Eating too many carbohydrate foods (such as potatoes and bread)
  • Gaining weight
  • Missing your medicine
  • Stress
