What Happens When Blood Sugar Is Too High

While glucose is important for the normal functioning of our bodies, too much or too little will cause problems. When blood sugar levels become elevated, it can lead to a range of health problems. These include diabetes, heart disease, and kidney disease. High blood sugar levels can also cause damage to the blood vessels, nerves, and organs in your body. This can lead to complications such as heart attack, stroke, blindness, kidney failure, and amputation.
High blood sugar can be caused by various factors, including insufficient insulin production, insulin resistance, certain medications, stress, illness, or an unhealthy diet. When left untreated, prolonged high blood sugar levels can damage blood vessels and organs throughout the body.
