12 Warning Signs of High Blood Sugar and How to Respond Early
High blood sugar, also called hyperglycemia, can affect anyone—not just individuals diagnosed with diabetes. Glucose is the body’s main source of fuel, but when levels rise and stay elevated for too long, it may affect how the body functions. This can happen due to factors such as stress, lack of physical activity, poor dietary habits, or certain health conditions. While symptoms may develop gradually, recognizing potential warning signs early can encourage timely lifestyle adjustments or professional guidance.
Some commonly reported signs that blood sugar levels may be higher than normal include increased thirst, frequent urination, persistent tiredness, or intense hunger. Other clues might include blurry vision, slow-healing cuts, recurring infections, tingling or numbness in the hands or feet, or dry skin and mouth. Some people also experience mood changes, mild swelling in the legs or feet, or breath that carries a slightly sweet scent. While experiencing these signs does not confirm high blood sugar on its own, they can serve as prompts to pay closer attention to your well-being.
