How much blood pressure will rise at 2000 meters above sea level cannot be determined due to individual differences, comorbidities and other differences. Normal healthy people at an altitude of 2,000 meters may experience an increase in blood pressure, but not necessarily beyond 140/90mmHg; hypertensive patients with significant fluctuations in blood pressure may be more than the normal obvious, an abnormal increase in blood pressure.
The altitude of 1520~3500 meters above sea level is regarded as high altitude. At 2000 meters above sea level, the lack of oxygen can cause many kinds of stress changes, resulting in the activation of the RASS system, and at the same time, the secretion of vasoconstrictive substances increases, and the sympathetic excitability also increases significantly, resulting in the increase of the heart rate accompanied by the increase in blood pressure, and the blood pressure of a normal healthy person may be elevated, but may not necessarily be more than 140/90mmHg.
Normal healthy people may have elevated blood pressure, but not necessarily beyond 140/90mmHg. Those who suffer from hypertension, especially those with unstable blood pressure control, are more prone to significant fluctuations in blood pressure than normal people, and may even suffer from dizziness and headache, with blood pressure as high as 180/120mmHg, accompanied by renal and craniocerebral damages in hypertensive emergencies.
If the patient’s blood pressure rises beyond the normal range at an altitude of 2,000 meters, accompanied by headache, panic and other discomforts, it is recommended to go to the hospital as soon as possible and follow the doctor’s instructions for treatment.
