The number of people walking around with high blood sugar levels without even knowing it is truly staggering. Part of that is because many people don’t know what high blood sugar symptoms actually look like. High blood sugar (or hyperglycemia) occurs when there’s a buildup of excess glucose in the bloodstream.
Early on, high blood sugar can make you feel off in a variety of ways, causing fatigue, frequent urination, headaches, and blurred vision.
Over time, untreated high blood sugar can cause additional symptoms, such as recurrent infections and tingling hands and feet. They could also have damaging effects on the vascular system, leading to long-term complications such as arteriosclerosis and diabetic retinopathy.
