5. Tingling and Numbness
Uncontrolled blood glucose can cause nerve damage called neuropathy. This happens as high blood glucose levels restrict proper blood flow to the extremities, which causes damage to the nerve fibers.
Neuropathy can cause symptoms like a tingling sensation or even numbness in your hands and feet. In some cases, the muscles in the legs and feet may weaken, making you unsteady.
So, if you begin experiencing tingling or numbness in your hands or feet, consult your doctor about your blood sugar levels before it starts interfering with your daily routine or your sleep.
6. Blurry Vision
If you suddenly notice that you are having vision problems, bear in mind that it can be due to poor diabetes management.
High blood sugar can lead to some degree of retinopathy, or damage to the light-sensitive tissue at the back of the eye. This happens as high blood glucose levels can damage the eye’s delicate blood vessels, which in turn makes it unable to properly focus, causing blurred vision.
Moreover, fluctuating blood sugar levels can make the lens of your eye shrink or swell, causing the vision to blur.
If you have sudden vision loss, see a specialist immediately.
