Normal: It's normal physiology for BP to fall by 10 points on standing initially followed by a rise in diastolic pressure first, then systolic pressure and accompanied by a rise in heart rate by 10 bpm. BP change will vary by hydration state and may be modified by any medications you may be taking. Caffeine, nicotine, alcohol and many herbal otc supplements will also affect it.
