The Centers for Disease Control and Prevention stated that about 29 million people across the US and about 9% of the population have diabetes. You can do three basic tests to help you find out.
Hemoglobin A1c Test
This test is a simple blood test, and it is done by taking a sample of blood from a finger-stick. It will show the average blood sugar level for the previous three months. And, if your hemoglobin A1c is in the range of 7%, you are less prone to have some problems with kidneys, eyes, and nerves.
Dilated Eye Exam
When it comes to diabetes and eyes, high levels of blood sugar and blood pressure can have an impact on the small blood vessels in the eyes. Damage can be prevented, and the best way to do that is to go to a doctor for a dilated eye exam. The doctor will enlarge your pupils for a small period of time, so he can examine the inside of your eyes and look for a sign of damaged blood vessels. It is really a painless test, but your eyesight will be decreased for a few hours after this exam.
In the end, you can go and do a foot exam since diabetes can slow circulation in the legs and feet.
The doctor will look for sores, open wounds, redness and cracks, and if something is suspicious, he’ll conduct a monofilament test. Here you will need to close your eyes and he will press a piece of nylon into several parts of your foot. And if you can’t feel anything, there might be a problem with nerve-damaging. There is also a test where the doctor will tap on your Achilles’ tendon in order to see if all the nerves on the back of your ankle are working. If they are, your foot will point downward.
