Patients with hypertension are not recommended to go to places with high altitude. This is because higher altitude will lead to hypoxia, and hypoxia in the body will react to vasoconstriction, causing a continuous increase in blood pressure. Long-term hypertension or sudden increase in blood pressure causes hypertensive crisis, which can cause cerebrovascular damage and aortic coarctation, and even inadequate perfusion of important organs, and once these conditions occur, the patient may have a life-threatening condition. Therefore, once hypertension occurs, while actively taking medication, you should also pay attention to a light diet, regular living, and refrain from going to high altitude places and doing dangerous recreational activities. While taking hypertension medication, you should have regular reviews and adjust the dose of medication according to the fluctuation of blood pressure.
