Blood Sugar Levels: What’s Normal What’s Not And How To Measure
What do blood glucose levels mean and what range is healthy? Here’s what you need to know.
Sugar can lead to high blood sugar and contributes to the development of diabetes.
We all want to keep track of our health in every way we can — you may weigh yourself, keep track of your blood pressure or monitor your resting heart rate. But how close of an eye do you keep on your blood sugar?
People with diabetes are all too familiar with their blood sugar levels, but the rest of us might not even think about it much. However, consistently high blood sugar levels can coexist with Type 2 diabetes and cause serious health conditions like kidney disease, nerve problems or stroke.
While that’s no reason to panic, when it comes to our health, it’s important to know exactly what’s going on inside of our bodies. Without further ado, let’s get into what blood sugar means, how to measure it and everything else you need to know.
Our Health & Wellness newsletter puts the best products, updates and advice in your inbox.
How The Test Is Done
You can buy a testing kit from a pharmacy without a prescription. Your provider can help you choose the right kit, set up the meter, and teach you how to use it.
Most kits have:
- Test strips
- Small needles that fit into a spring-loaded plastic device
- A logbook for recording your numbers that can be downloaded and viewed at home or at your provider’s office
To do the test, prick your finger with the needle and place a drop of blood on a special strip. This strip measures how much glucose is in your blood. Some monitors use blood from areas of the body other than the fingers, reducing discomfort. The meter shows your blood sugar results as a number on a digital display. If your vision is poor, talking glucose meters are available so that you don’t have to read the numbers.
Be aware that no meter or strip is accurate 100% of the time. If your blood sugar value is unexpectedly high or low, measure again with a new strip. Do not use strips if the container has been left open or if the strip has gotten wet.
