Eating too much has an effect on blood pressure, but the change in blood pressure is small, only mildly elevated and remains within the normal range, and some people may have problems with postprandial hypotension.
Blood pressure mainly refers to the lateral pressure of flowing blood on the wall of a blood vessel per unit area, which can be divided into systolic and diastolic blood pressure. Normal values for systolic blood pressure are 90-139 mmHg, and normal values for diastolic blood pressure are 60-89 mmHg. Factors affecting blood pressure include the volume of the heart per beat, peripheral resistance, heart rate, the role of elasticity of large arteries reservoirs, and the volume of circulating blood.
When eating too much, a large amount of food will cause strong gastrointestinal peristalsis, leading to an increase in its blood demand, the heart also increases the amount of blood discharge, and then there can be a slight increase in blood pressure of the phenomenon, but generally does not exceed the normal value, is a physiological situation, without special treatment.
Part of the population, especially the elderly is common, due to circulatory problems, after meals, a large amount of blood into the digestive tract to ensure digestion, prone to postprandial hypotension.
To summarize, eating too full has a small effect on blood pressure. If blood pressure fluctuates greatly after a meal, it is necessary to suspect the existence of other diseases, and please consult a doctor in time.
