<s>[INST] My Mum has always had low blood pressure, however the last year through what I believe to be stress related has caused her bllod pressure to be high. Her doctor has put her on blood pressure medication and for the last two days her blood pressure has been really low. She has felt faint and her heart is racing at 99 beat pm should she be going to the hospital? [/INST] hi,it's certainly a matter of concern, get a electronic bp apparatus and monitor bp. Also ask your doctor to decrease the dose of bp medicine. till the time she can salt,sugar water whenever bp goes down. </s>
