If your A1C is high, it may indicate that your blood sugar levels have been consistently elevated over a period of time. High A1C levels can lead to a range of symptoms, such as increased thirst and urination, blurred vision, slow healing of cuts and wounds, fatigue, and weight loss. In some cases, high A1C levels may also lead to complications such as diabetic retinopathy, neuropathy, and nephropathy. It is important to note that some people may not experience any symptoms even if their A1C levels are high. In such cases, regular A1C testing is crucial for the early detection and management of diabetes. If your A1C is high, it is important to work with your healthcare provider to develop a plan for managing your diabetes and reducing your A1C levels.
