You should check your blood pressure at home at least once a day, three to five times a week. Two to three measurements a day would be ideal, but at least one, at different times of the day, is okay. The morning blood pressure may be different than the afternoon blood pressure, which may be different than the evening blood pressure.
If a larger size is needed then contact the company supplying your blood pressure device. Always measure your blood pressure at the same site (thigh, calf or ankle) and at the same time of day. Do it at least once, and preferably twice, each day and keep a record. (Ideally this is for 7 days before you go to your GP)
