Glucose is fuel for our organism. Our body gets glucose from the food we consume, spitting carbohydrates. For absorbing glucose, the pancreas produces the insulin hormone, which regulates the level of glucose in the blood. Certain diseases, poor nutrition, stress, lack of sleep, and exercise may cause insufficient production of insulin and an increase in blood sugar level.
If it happens, it may have a drastic impact on the nervous, digestive, cardiovascular, and other systems. That is why it is crucial to monitor blood glucose levels as the diet and lifestyle of most modern people greatly increase the chances of diabetes development compared to our predecessorі.
So, what is a normal blood glucose level? How to prepare for a glucose tolerance test? And what does it mean when your blood sugar is high? These and many other equations we will answer in this article. Keep on reading!
Of course, the numbers of the so-called “norm” are always relative and vary depending on individual factors such as age, gender, lifestyle, diet, medical conditions (pregnancy, for example), and so on. Thus, the normal glycemic level for a healthy adult person on an empty stomach varies from 3.3 to 5.5 mmol/l, and after meals – 5.6-6.6 mmol/l. If the second index is achieved during the empty stomach blood sugar measurement, it means that insulin sensitivity is violated.
If the index of measuring blood sugar on an empty stomach exceeds 6.7 mmol/l is an indicator of hyperglycemia (high blood sugar). Hyperglycemia may be a sign of other disorders:
If the symptom is chronic, then it is likely that the patient has diabetes.
The number down 3.3 mmol/l, on the contrary, is a sign of hypoglycemia – low blood sugar, a medical condition that can lead to cramps, headaches, disorders of the pancreas, liver, kidneys, and adrenal glands.
Regular monitoring of sugar levels in the blood helps to detect and prevent further development of hyper- and hypoglycemia.
There exist a few ways to monitor blood glucose to prevent developing diabetes:
These are diabetes tests for people who have been already diagnosed with diabetes mellitus type 1 or type 2 or for patients who have risk factors of developing diabetes. Healthy people with no major health problems do not need such intense diabetes care.
However, the above-mentioned categories of insulin-dependent patients should be especially careful to maintain insulin and glucose within normal ranges.
To get accurate blood glucose test results, you should follow simple recommendations. Otherwise, you will get unrealistic results and will have to repeat the test if you do not want to get the wrong diagnosis and inappropriate treatment correspondingly.
Can I drink water before the test?
Yes. You can drink water but exclude all other drinks, especially the ones containing alcohol or sugar.
Preparation for blood glucose test
What can I not eat before the blood sugar level test?
As I have mentioned before, there are many external factors that may either temporarily increase or decrease blood glucose level. Here are the main of them:
As you see, many different aspects may have an impact on the blood glucose test result. That is why you should do the testing regularly to have the most precise and adequate understanding of your blood glucose levels.
It is important to monitor normal blood glucose levels regularly to prevent diabetes mellitus and remain healthy. However, many people neglect medical care and checkups if nothing bothers them. If you decide you want to measure your blood glucose, this is the best time to do this:
Neglecting any of the above-mentioned recommendations will have a direct impact on the blood glucose test, and you will not get precise results.
Hyperglycemia or high blood sugar is a condition that may lead to the development of diabetes. There are cases when hyperglycemia may be temporary, as in the case of gestational diabetes, but in any case, it demands careful regular monitoring of high blood sugar, adjustment of lifestyle, diet, physical activity, and if needed, implementation of insulin medication treatment to maintain a normal level of blood sugar.
Hypoglycemia or low blood sugar is a medical condition opposite to hyperglycemia. The interesting thing is that it can develop just in people with diabetes who are taking insulin for glycemic control. When taking too much insulin, the level of glucose in the blood may suddenly decrease. All patients should be aware of hypoglycemia symptoms:
The lower the indicator, the higher the risk of developing hypoglycemic coma.
When diagnosing diabetes, high blood sugar is one of the leading factors indicating there is a problem with insulin sensitivity. Of course, one test result is not a reason to diagnose a disease, and a number of other analyses will be required for an accurate diagnosis. Still, in any way, it is a reason to take care of your health, reconsider your lifestyle and diet.
Thank you for your attention, and have a wonderful day!
