What are the signs of high postprandial blood sugar?

Signs of high postprandial blood sugar include fatigue, excessive thirst, frequent urination, blurred vision, and sometimes headaches or nausea. Long-term effects of elevated post-meal glucose levels include an increased risk of cardiovascular issues, nerve damage, and kidney problems. If you experience these symptoms frequently, a PPBS test can help confirm whether your blood sugar levels are poorly managed.
