What is a Normal Blood Glucose Level for Adults?

Normal Blood Glucose Level for Adults.

What is a normal blood glucose level for adults? The answer to this question comes with several variables, though providing accurate details will be no problem. After considering much scientific research and common statistics that can be found across the Internet, there is no doubt in my mind that you will be able to find the answers that you need to this question. Keep in mind that many people who are asking this question are already at risk for diseases and conditions directly related to blood glucose, and as such should consistently check their numbers and meet with a family doctor if need be.

With that little tangent aside, answering the question “What is a normal blood glucose level for adults?” is fairly easy to do. The first set of numbers I will provide you are the average scores you should expect throughout a regular day. Please note that these do tend to fluctuate from time to time, and some further explanation will be given with regards to why this is. The average blood sugar level for adults is between 70 and 140mg/dL. Some people may experience numbers as high as 180mg/dL after partaking of food. The reality of blood sugar levels is that they constantly are moving as your body utilizes sugar for a multitude of purposes.

Still, in asking what is a normal blood glucose level for adults you will want to also consider the fasting blood sugar range. If you are taking a period of time off from eating, you may want to consider this number. Additionally, the “fasting range” is generally considered to be valid early in the morning shortly after you wake up. In general, the fasting blood glucose level you can expect is around 72mg/dL. This is a great resting rate to be at, though you will undoubtedly be between 70 and 80mg/dL on average. As you can see, your blood sugar levels may fluctuate significantly throughout the day depending on many factors.


As far as answering the question “What is a normal blood glucose level for women?” you should also consider the negative consequences that can arise if you do not stabilize your sugar levels. Hyperglycemia results if your blood sugar levels stay elevated above 180mg/dL for a long period of time. This condition negatively impacts your health in many ways, and can lead to high blood pressure as well as cardiac arrest. Hypoglycemia can arise from having low blood sugar levels over a long period of time. Similar problems can arise from this condition as well. As you can see, the negative effects of unregulated blood sugar levels are very significant.

So, what is a normal blood glucose level for adults? The reality is that it can fluctuate for many individuals depending on a large array of factors like race, ethnicity, socioeconomic status, weight, among other things. If you feel that your blood glucose levels are not properly regulated, you should immediately consult a doctor.

Thank you Connie - very interesting piece. Like you I wish I knew what the correct level is. I know what level I feel most comfortable at and assume that's good for me. I use full retinal scans regularly and they indicate that there is no trace of diabetes and all of my other signs are normal - so I must be doing something right.

The thing that worries me is how ignorant the medical profession is about diabetes. I have had nurses trying to inject me with insulin in the midddle of a hypo and vice a versa.

Great information to keep in mind as I have been having trouble with my blood sugar. I have been told that I am danger of developing diabetes. However, my doctors have not given me any way to test my blood sugar level. As far as I know, you have to have a prescription to get the devices to do so. I'll have to check into it more after having read this hub. Thanks for the information.

Diabetes is fast spreading due to a changed food culture and lack of physical activities. Awareness is essential and you contribute to that.
