Postprandial hypotension usually occurs in the elderly, and the prominent manifestation is that the systolic blood pressure (high pressure) is 20 mm Hg lower than normal 30~60 minutes after meals, and it returns to normal after 2~3 hours. About an hour after a meal with the lowest blood pressure, dizziness and light footsteps are prone to occur, and the blood circulation in the brain is obviously slowed down.
If you want to prevent postprandial hypotension, you must develop the basic eating habits of chewing slowly and eating more and less meals. In addition, drinking a cup of coffee or a cup of green tea before meals can effectively prevent postprandial hypotension, because caffeine in tea and coffee can inhibit the release of enterokinase in large quantities and prevent blood pressure from dropping rapidly in a short time.
