Continuous blood pressure fluctuations are both individual and normal. It is not uncommon for blood pressure to be higher at the clinic than when you check it at home. If you have diabetes, it is recommendable to get your own blood pressure monitor and use it at home on a regular basis.
You can ask your treatment centre about borrowing a blood pressure monitor, if you do not have one of your own. You can also check your blood pressure at self-care points in health clinics or pharmacies. If necessary, a separate 24-hour blood pressure monitoring can be performed, during which blood pressure is monitored with a portable blood pressure monitor.
If you are elderly or if you have vertigo, you should check your blood pressure while sitting down and a minute after standing up.
