Normal Blood Sugar Levels Chart for Adults

Paying attention to the following normal blood sugar levels chart can help you to control your glucose levels.

normal blood sugar levels chartWhen we eat, if our digestive systems are functioning correctly, the food is converted into glucose – also known as blood sugar. Once the food is converted to glucose, the cells of the body are able to feed on it.

Although, glucose is essential to the correct functioning of the body, it has to be kept in balance. Too much glucose, and the various organs of the body begin to shut down. Consistently high levels of glucose in the bloodstream is a symptom of diabetes. And untreated diabetes can result in blindness, liver failure, and damage to many of the essential organs of the body.

Too little glucose in the bloodstream is not healthy either. An insufficient amount of glucose in the bloodstream can lead to symptoms such as anxiety, heart palpitations, confusion, nervousness, and more. Consistently low levels of glucose in the bloodstream is a symptom of hypoglycemia. So, as you see, keeping blood sugar levels normal is a key prerogative for staying healthy.


So What Are Normal Blood Glucose Levels?

In a typical person, the normal blood sugar level will be somewhere between 70 and 140 milligrams per deciliter. with slight fluctuations throughout the day. If it goes above 140 during the day, you are entering dangerous territory.

In the mornings, the blood sugar level is typically lower. This is because the body has been using glucose in the blood to provide itself with the energy needed to repair and replace the cells of the body. And, after a meal, the blood glucose levels normally rise as the body converts the just eaten carbohydrates to sugar. And normally, within minutes, your pancreas will release insulin into the body to regulate the sugar and to ensure that it doesn’t get too high. If it does get too high (or too low), and stays that way for an extended period of time, then you have a problem.

What Should Your Fasting Blood Sugar Numbers Be?

The best time is test you blood sugar is after an extended period (approximately 6-8 hours) of not eating. Doctors refer to this as your fasting blood sugar level. Immediately after eating is too soon to test because it is artificially elevated. Waiting too long is bad also as it will give you a misleading low number. That’s why, for most people, the best time to take the tests is in the morning just before breakfast. The normal fasting blood sugar level should be in the neighborhood of between 70 and 110 milligrams per deciliter, with most people falling into the lower part of this range. Note that the fasting blood sugar level is different from the “normal” blood sugar level that you have throughout the day as you go through your various daily activities.

Unless you have been diagnosed with diabetes, you don’t have to worry about your blood glucose levels from day to day. It’s enough to have your blood sugar levels tested during your annual visit to the doctor. He can use an oral glucose tolerance test, or an alternate blood glucose test, to determine your body’s level of blood sugar control.

If you have diabetes, however, you may have to submit to blood glucose monitoring. You may have to test your blood glucose levels at periodic times throughout the day to ensure that it stays within normal limits. You can manage this very easily by using one of the many glucose monitors that have entered the marketplace in recent years.

What Happens If Your Blood Sugar Level Gets Too Low?

If your blood sugar level falls below 70, you will normally start to experience physical symptoms. Specifically, you may develop tremors, heart palpitations along with rapid heartbeat, and the loss of concentration. Further drops in blood glucose may result in seizures and even losing consciousness.

How Does The Body Maintain A Normal Blood Sugar Level?

Your blood glucose levels are regulated by the insulin and glucagon hormones.

In type I diabetes patients, high blood glucose is caused by the body’s inability to produce enough insulin to regulate the amount of glucose entering the bloodstream. As a result, the body tries its best to get rid of it through urine. If untreated, however, eventually the levels of sugar in the blood will rise so much that the body will not be able to get rid of it fast enough. This is when real damage begins to happen to the internal organs of the body.

Glucagon, in contrast to insulin, raises the blood glucose levels. In those experiencing hypoglycemia, it can be injected to raise the blood sugar level.

Other Factors That Affect Blood Sugar Levels – Normal and Abnormal

When measuring blood sugar levels, you should be aware that food isn’t the only thing that affects those levels. Any physical activity that requires a moderate degree of activity can affect it as well. This includes activities such as normal exercise routines, running, sports activities, and the like. And, surprisingly, illnesses and injuries can affect it as well. This is due to the body using more glucose from the bloodstream to help heal the body.
