Low blood pressure after eating (postprandial hypotension). Low blood pressure from faulty brain signals (neurally mediated hypotension).
Low blood pressure is defined by a blood pressure reading of 90/60 mm Hg or lower , but a reading this low isn’t necessarily a cause for concern. It becomes a concern if you start to exhibit symptoms of dizziness, shortness of breath, or fainting; if this happens, you should seek medical attention.

A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure — a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher — can damage blood vessels.
Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 140/90. Stage 2 high blood pressure is 160/ 100 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away.
As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
