You can’t go to Tibet if your blood pressure is not under control, but you can consider going to Tibet after it is under control.
Whether patients with high blood pressure can go to Tibet or not should be decided according to the degree and control of individual’s blood pressure condition, and cannot be generalized.
Patients with high blood pressure who have been taking antihypertensive drugs for a long time and whose blood pressure can be controlled within the target range, i.e., systolic blood pressure is lower than 140mmHg and diastolic blood pressure is lower than 90mmHg, these patients can go to Tibet.
Patients with high blood pressure have recently increased significantly, especially systolic blood pressure is higher than 180mmHg, diastolic blood pressure is lower than 110mmHg or more, reaching the degree of grade 3 hypertension, blood pressure is not completely controlled before the stable is not recommended to go to Tibet.
Tibet has a cold climate, thin air, and a lack of oxygen, so hypertensive patients going to Tibet are prone to vasoconstriction, which can lead to blood vessel rupture and cause intracranial hemorrhage and other dangerous situations.
The specific situation varies from person to person, you can consult a specialist physician to make a comprehensive assessment before making a judgment.
