Bai Haipeng introduced that the low blood pressure after meal is caused by blood redistribution. When eating, food is absorbed and metabolized in the bodys intestines and stomach, causing blood to accumulate in the blood vessels of the gastrointestinal tract. Because the blood volume of the whole body is fixed, when the blood is concentrated in the gastrointestinal tract, the peripheral blood vessels will be relatively insufficient Bai Haipeng explained.
The common symptoms of postprandial hypotension are sleepiness, dizziness, weakness and even syncope. Bai Haipeng reminded that if the patients themselves have insufficient cerebral blood supply, these symptoms will be more obvious, which may lead to stroke or even life-threatening.
Drink water before meals and lie down after meals
Drinking 350 ml-480 ml water before meals can reduce the range of postprandial blood pressure drop by about 20 mmHg. However, patients with severe heart failure and end-stage renal disease who need to limit water should drink water carefully; eat less and more meals, reduce carbohydrate intake, and increase food rich in protein and fiber, which is conducive to improving postprandial hypotension. Bai Haipeng suggests that the elderly with a history of postprandial hypotension should lie down for half an hour after meals, and do some hand and foot activities in bed to improve heart rate and blood pressure. When the body position changes, they should be slow, and then they should take appropriate exercise such as walking.
Bai Haipeng said that rational drug use is essential to prevent postprandial hypotension. The higher the pre meal blood pressure, the greater the probability of postprandial hypotension. We can reduce the incidence of postprandial hypotension by reasonable antihypertensive treatment (especially effectively reducing morning blood pressure)
