What Causes Persistent High BP Levels?
Not a bad idea to use BP monitors...
I went through the details. If your mom had recorded high BP numbers on more than 2 occasions, then it is not a bad idea to buy and regularly monitor blood pressures. There are various digital BP monitors available to choose from. You can buy one which is easy to handle / use. Please note that almost all BP monitor would show a fluctuation of 10mmHg from actual readings.
If there is no known cause of high BP, then she has essential or primary hypertension which is not uncommon. If her BP is above 140/90 mmHg on more than two occasions, it is better to consider starting antihypertensive drugs.
Hope I have answered your question. Let me know if you were looking for any other information.
Thank you for the reply.
