Holding urine may cause the patient’s blood pressure to rise, so that is why when measuring blood pressure, patients are advised to not only stay in a resting state, but also to urinate before taking the blood pressure, because holding urine itself will cause the patient’s blood pressure to rise, which will affect the accuracy of the blood pressure. Patients are advised not to be active or agitated when measuring their blood pressure, and it is best to measure it in the morning after urinating in a resting state. Patients are also not advised to smoke before taking their blood pressure, as taking their blood pressure just after smoking can also affect it. If you want to objectively assess the patient’s overall blood pressure, it is recommended that the patient have an ambulatory blood pressure monitor if necessary, which can assess the patient’s overall blood pressure over a 24-hour period, so that you can assess whether the patient currently has abnormal blood pressure.
