If your blood sugar levels are high at one hour (196) and two hours (164) during an Oral Glucose Tolerance Test (OGTT), it indicates a potential problem with glucose metabolism. These elevated levels may suggest impaired glucose tolerance or diabetes. It is important to consult with a healthcare professional for further evaluation, diagnosis, and appropriate management of your condition. They may recommend additional tests or lifestyle changes to help regulate your blood sugar levels and prevent complications associated with high glucose levels.
