A blood pressure reading of 117/49 mmHg shows a systolic pressure (the top number) of 117 and a diastolic pressure (the bottom number) of 49. In general, a normal blood pressure reading is usually around 120/80 mmHg.
While the systolic value of 117 is considered normal, the diastolic value of 49 is on the lower side. This could indicate low diastolic blood pressure (often referred to as diastolic hypotension), which might cause symptoms such as dizziness or fainting in some individuals, particularly if the person is symptomatic.
It's important to consider individual factors such as age, overall health, and any symptoms you may be experiencing. If you have concerns about your blood pressure or any symptoms, it's advisable to consult a healthcare professional for further evaluation and advice.
