A sudden increase in blood pressure cannot be definitively diagnosed as a patient with hypertension. A patient with hypertension is diagnosed as a patient with hypertension only if the systolic blood pressure is greater than or equal to 140 mmHg, and or diastolic blood pressure is greater than or equal to 90 mmHg, measured on different days, at different times, and multiple times. For a particular increase in blood pressure, it is important to consider whether there is a stressful factor, such as an increase in blood pressure caused by the patient engaging in a lot of physical activity or sudden panic, anxiety, or emotional disturbance. This type of elevated blood pressure is transient and will improve if the patient relaxes, rests in place, and has his or her blood pressure measured again after 15-20 minutes of adjustment. If self-regulation has no effect, and blood pressure is found to be high on different days and at different times, and hypertension is highly suspected, the patient should go to the cardiology department of the local hospital to have the patient seen by a cardiologist to determine if the patient is simply hypertensive or if the hypertension is caused by a combination of other diseases. If other diseases are combined, the patient should be treated for the cause. If primary hypertension is considered, the patient should take antihypertensive drugs under the guidance of a doctor.
