Hi, welcome to health care magic You are on 3 medications that would reduce your blood pressure- lisinopril ( which would also protect your kidneys from damage due to diabetes), hytrin and metoprolol ( can be used for hypertension, also used in angina/ chest pain due to blockage of blood vessels in the heart by cholesterol plaques and in heart failure). White coat hypertension is accurately diagnosed by 24 hr blood pressure monitoring where the blood pressure is checked in your doctor s office and then at home or any other settings to see if it varies. White coat hypertension is important because you have an increased risk of developing hypertension later which of course you would know has its risks. When you are checking your blood pressure at home to compare it to the one you get at your doctor s office, you should do the following: no exercising for at least 30 min before, no coffeee, cigarettes before doing reading, sit quietly for at least 5 mins, with your feet on the ground before doing the test. In terms of the blood pressure reading above: blood pressure readings vary from person to person and what may cause symptoms in one person may not cause any in another. Blood pressure readings may vary between 90/60 to 130/80. The possible causes of low blood pressure include: medication, dehydration, fainting, advanced diabetes, heart disease, alcohol, severe allergic reaction, some persons blood pressure may fall when they stand as well. If you are having symptoms such as dizziness, confusion, weakness, lightheadness, sleepiness then you should consider visiting your doctor for a check up and possible modification of your medication. I hope this information is helpful to you, wish you the best
