Hi,
Fluctuations in blood pressure levels can be caused by a variety of factors such as stress, anxiety, physical activity, medications,
dehydration, and medical conditions like
heart disease or thyroid disorders. It is possible that the change in medication could be causing fluctuations in your blood pressure levels, but it is best to speak with your doctor about this.
As for when to be concerned about low blood pressure readings, it depends on your health status and medical history. Generally, a blood pressure reading of 90/60 mmHg or below is considered low, but some people may experience symptoms of low blood pressure at higher readings.
Symptoms of low blood pressure can include
dizziness,
lightheadedness,
fainting, and nausea. If you experience any of these symptoms or have concerns about your blood pressure, it is best to speak with your doctor as soon as possible.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
