Methods for assessing fasting blood sugar:

  2. Glycosylated hemoglobin (HbA1c) test: In this type of test, Hemoglobin A1c levels are checked over a period of 2-3 months. The higher the Hemoglobin A1c level, the higher the chance of being a diabetic.

Methods for assessing non-fasting blood sugar:

  • Exercise regularly to keep your body weight in control. This helps in improving insulin sensitivity in your body
  • Control the intake of carbohydrates which break down into glucose. When the intake of carbohydrates is high, the blood sugar levels also get high. Low carbohydrate diet keeps amount of blood sugar normal.
  • Increase the intake of high fiber diet which helps in regulating the blood sugar. Fiber is slows down the digestion of carbohydrates by the body which ultimately keeps the blood glucose level in control.
  • By drinking plenty of water in a day one can easily maintain the limits of blood sugar. Adequate amount of water in your body enables the kidney to easily flush out the excessive amount of glucose in your body.
