Why Does My Blood Pressure Fluctuate?

Most trips to the doctor’s office will include a blood pressure reading. That’s because your blood pressure can tell your doctor a lot about your health. A number that’s a little low or a little high may be a sign of potential issues. Changes in your blood pressure between visits can be an indication of health issues, too.

Your blood pressure is a reading of the force with which blood is passing through your circulatory system. Blood pressure changes naturally many times a day. Most changes are normal and predictable. When these spikes and valleys in your blood pressure occur, you may not experience unusual signs or symptoms. These fluctuations may be brief and fleeting. Learn more about blood pressure readings.

However, if you notice that the high pressure readings are really high or the low pressure readings are unusually low, you may want to speak with your doctor. When you notice these changes, it’s important you record them in a log. Write down your numbers, your activities, and how long it took for the number to reach normal again. This information may help you or your doctor detect a pattern or a problem.


Fluctuating blood pressure can be caused by several issues.


Emotional stress and anxiety can temporarily increase blood pressure. Over time, excess stress can take a toll on your cardiovascular system and might lead to permanent blood pressure problems. Find out more about the effects of stress on your body.
