1 Fasting plasma glucose test. 2  The doctor tests your blood sugar level after fasting for 8 hours and it’s higher than 126 mg/dL. 3  Oral glucose tolerance test. 4  After fasting for 8 hours, you get a special sugary drink. 5  Two hours later your sugar level is higher than 200. 1 The doctor tests your blood sugar level after fasting for 8 hours and it’s higher than 126 mg/dL. 2  Oral glucose tolerance test. 3  After fasting for 8 hours, you get a special sugary drink. 4  Two hours later your sugar level is higher than 200. 5  Random check. The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis.  And it's less than 140 mg/dL 2 hours after eating. During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90. 1 The doctor tests your blood sugar level after fasting for 8 hours and it’s higher than 126 mg/dL. 2  Oral glucose tolerance test. 3  After fasting for 8 hours, you get a special sugary drink. 4  Two hours later your sugar level is higher than 200. 5  Random check. Diabetes drugs aren't the only medications that affect blood sugar. The following is a list of drugs that may cause highs and lows. Because of the constantly changing nature of the U.S. prescription and OTC drug marketplace, this list may not reflect the full range of drugs that may impact blood sugar levels.  A. Normally, insulin is released from the pancreas when the amount of sugar (glucose) in the blood increases, such as after eating. Insulin stimulates the liver and muscles to take in excess glucose. This results in a lowering of the blood sugar level.  How Blood Sugar Affects Your Body. When you have diabetes, your blood sugar (glucose) levels are consistently high. Over time, this can damage your body and lead to many other problems. 1 The doctor tests your blood sugar level after fasting for 8 hours and it’s higher than 126 mg/dL. 2  Oral glucose tolerance test. 3  After fasting for 8 hours, you get a special sugary drink. 4  Two hours later your sugar level is higher than 200. 5  Random check. Check your blood sugar level. Check your blood sugar level before, during and after exercise, especially if you take insulin or medications that lower blood sugar. Exercise can lower your blood sugar levels even a day later, especially if the activity is new to you, or if you're exercising at a more intensive level. If you use insulin and your blood sugar level is below 100 milligrams per deciliter (mg/dL), or 5.6 millimoles per liter (mmol/L), have a small snack before you start exercising to prevent a low blood sugar level. 1  Stay hydrated. 2  Be prepared. 3  Adjust your diabetes treatment plan as needed. What Affects Blood Sugar Levels. Food, exercise and medication all affect blood sugar levels. Getting blood glucose levels right can prove to be difficult at times. Just when you think you've factored everything in, a high or low blood glucose level can arrive out of nowhere and really throw your confidence. Exercise or just increasing exertion can lead to altering blood glucose levels: 1  Physical activity can affect insulin sensitivity for up to 48 hours-which can lead to lower blood sugars over this time. 2  Sugar levels can initially rise following a short burst of activity Physical activity.
