There are many reasons for high blood pressure, which may be due to physiological factors or pathologic factors. It is recommended to consult a doctor for further clarification of the cause of the disease. 1. Physiological factors: If the blood pressure is high after strenuous exercise or emotional stress, physiological factors should be considered and it is recommended to re-measure the blood pressure after resting and calming down. 2. Pathological factors: If there is dizziness, headache or even vomiting, it is necessary to consider whether there are pathological factors, such as primary hypertension, secondary hypertension caused by renal disease and other diseases. Further cardiac ultrasound, renal ultrasound, 24-hour ambulatory blood pressure and other examinations are needed to further clarify the cause of the disease.
