Blood pressure does not usually rise after breakfast, but if the patient eats quickly or is overly excited, this can cause sympathetic arousal, which may cause a rise in blood pressure. If you eat too much breakfast, the blood will be redistributed and transferred to the digestive system, in which case the blood pressure will have a mild decline, but not noticeable. Hypertensive patients should not eat too salty food, because it will cause sodium retention and increase blood pressure, usually do not eat too fast at breakfast, chew and swallow slowly, and talk less to avoid blood pressure rise.
