Abstract
- Postprandial hypotension is an important minor clinical problem. It is a common disorder that causes unexplained dizziness, falls, lightheadedness, syncope, angina pectoris, and even transient ischemic attacks of the brain. It is often defined as a decrease in systolic blood pressure by more than 20 mmHg within 2 hours after a meal. The mechanism of postprandial hypotension is splanchnic blood pooling via the loading of glucose in the intestine and decompensation of the autonomic nervous system. The best tool for detecting a fall in systolic blood pressure is 24-hour ambulatory blood pressure monitoring. Acarbose, an alpha-glucosidase inhibitor, is very useful for preventing postprandial hypotension. We experienced a case of postprandial hypotension that presented with postprandial dizziness. The patient was treated successfully with acarbose before each meal.
