Normal Glucose Levels: How High Can Blood Sugar Go To Be Normal?

If you have been showing , or you are at risk for , you should . Testing will determine whether you are currently not diabetic, pre-diabetic, or already have diabetes. ?

Blood sugar can be measured after fasting (not eating) for 8 hours, or as a random sample (measured any time during the day).

Normal blood sugar levels are:

  • Between 70 mg/dl and 100 mg/dl (3.9 mmol/L to 5.5 mmol/L) after fasting; or
  • Not more than 200 mg/dl (11.1 mmol/L) for a random sample.

In people without diabetes, then, blood sugar should not normally be higher than 200 mg/dl (11.1 mmol/L).

 

Taking Stock of How You Feel

It's not always appropriate to assume that everything's fine if your blood sugar is within normal levels. Our bodies all respond differently. For example, have you ever noticed that you feel sleepy after a big meal? Some people are very familiar with this feeling, and it can be a result of blood sugar spiking after consuming large amounts of food.

It's always best to have a frank & open discussion with your doctor about any symptoms of diabetes you may have been experiencing, or really, anything unusual or different from normal. If you notice that you've been feeling a little "off" after eating certain foods, or at certain times of the day, keeping track of these dates / times / meals can be a helpful tool for your doctor (and for yourself too).

Getting Your Blood Sugar Levels Back To Normal

The first step is to talk to your doctor and get blood glucose tests done, if you haven't done so already. This will tell you whether or not you're clinically considered or diabetic.

Your doctor will go over options with you. Sometimes diabetes can be adequately controlled with exercise and dietary changes; sometimes medication or insulin will be needed.

Everyone also responds differently to exercise and diet. Get a good glucometer that you're comfortable with and test your blood sugar regularly. This is especially important when you're first learning how your body responds to treatment. It might take several weeks or even several months before you're able to figure out what works best for you. Things that you can change up include:

  • What time you exercise - before or after meals, before bed, first thing in the morning?

  • How frequently you exercise - this doesn't mean you need to exercise for an hour every time, but perhaps shorter sessions more often will work better than a single, longer exercise session.

  • What time and how frequently you eat, and the size of the meal. The goal is to try to maintain a fairly steady blood sugar level throughout the day, avoiding spikes and lows if you can. But this can be very different for individuals - some people might find it works best for them to eat their starches in the morning only; others might spread them throughout the day; some might avoid starches before bed. Likewise, you may have to eat dinner earlier or have a smaller bedtime snack in order to get your fasting blood sugar within your recommended range.

The question of "how high can blood sugar go to be normal" can certainly be looked up on a standard chart, but health care is individual - talk to your doctor to find out what your goal should be. Some people will have a harder time than others maintaining a "normal" blood glucose.
