I wonder what the correct position is?
Sai Baba said that His blood pressure was always a solid 120/80, perfectly normal
Mine is fluctuating like crazy. I have severe kidney insufficiency, hence eating has a huge impact on BP readings. Mine goes as low as 72/36 (lowest), but normally 90/50. Unless I eat very, very little then it's 120/80
IMO, it's best is to check always in the same way, same time,same position, same amount of food eaten (eating is stress, esp. if you have an allergy) etc.
What causes blood pressure to rise and drop quickly?
Anxiety, stress, drugs, alcohol, physical exercise, and a range of medical conditions such as sleep apnea and kidney disease can cause your blood pressure to fluctuate from high to low. It's normal to see some variance throughout the day but you should consult a doctor if you exhibit symptoms of labile hypertension.
