High or low blood pressure after meals

High blood pressure refers to the phenomenon that the pressure of flowing blood on the wall of blood vessels is continuously higher than normal. In younger patients with hypertension

heart pumps more blood to the digestive system after meals, resulting in an increase in heart rate and a short-term increase in blood pressure.
