Causes of low blood sugar

One of the best ways for you to control your sugar levels is to know what causes them to go up. By knowing the causes, you can take steps to stay away from or lessen the causes.

Causes of high blood sugar include:

  • Too much diabetes medicine
  • Too much exercise
  • Not eating enough carbohydrate foods
  • Alcohol, like beer or wine


Treatment of low blood sugar levels should follow the Rule of 15.
  • Eat 15 grams of fast-acting sugar (1/2 cup juice, ½ can coke, 3 or 4 pieces of hard candy or 4 glucose tablets)
  • Re-check your blood sugar in 15 minutes
  • Treat it again with 15 grams of fast-acting sugar if your blood sugar is still less than 70 mg/dl.
