Conversation: The conversation between human and AI assistant.
[|Human|] My 88 year old grandmother has always had high blood pressure, and she is on 2 medications for it.  This afternoon while she was at the dentist, the assistant took Nanas blood pressure and mentioned that it was low -- 111/44.  What could cause this?  Its NEVER been this low.  She thinks its just stress, as my father (her son) died a couple of weeks ago.
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that these blood pressure values are not too low. The low diastolic pressure could be related to her age. Her antihypertensive therapy plays an important role in this blood pressure value too. But, as long as she has no symptoms like lightheadedness, dizziness, or blurring vision, there is nothing to worry about! If she experiences such symptoms and her blood pressure values are low all the time, I would recommend making some changes to her actual antihypertensive therapy. Hope you will find this answer helpful! Wishing all the best,
