High & Low Blood Pressure board


Not knowing anything else about your age or state of health, all I can say go to your doctor and have everything checked out. Thorough thyroid testing - not just TSH as this isn't good enough. Have your potassium, magnesium, vitamin D, and even vitamin B12 checked. Other tests to consider is an EKG, a holter monitor, and even regularly checking your own blood pressure and heart rate.

Has it been hot where you live and have you been out in it? How high is your heart rate getting? The thirst could be directly related to the higher heart rate, possible low blood volume, or the heat if you've been out in it too much lately. What's your average blood pressure and heart rate when sitting and/or standing?
