The first thing to consider is that the increase in blood volume is related to the increase in blood pressure. During the eating process, after eating soup, porridge and greasy food, it may lead to an increase in blood volume, which will increase the load on the heart, thus raising the blood pressure. Another aspect should be noted whether there is a problem of increased excitability, after eating, the body’s sympathetic nerve excitation, sympathetic nerve excitation will lead to small arteries throughout the body constriction, which will lead to the patient’s blood pressure rise. In addition, it should be noted that the patient may eat greasy food, such as animal offal, which increases the level of lipids in the blood, and after increasing the level of lipids, it will also increase the patient’s blood pressure.
