Blood pressure of 50 mmHg, if it is systolic pressure of 50 mmHg may be in a state of shock, is very serious. Diastolic blood pressure of 50mmHg is also abnormal. The normal range of diastolic pressure (low pressure) is 60-90mmHg, and low pressure below 60mmHg is called hypotension. If a patient who is normally hypertensive develops a low pressure of 50 mmHg, accompanied by symptoms of hypotension such as dizziness, weakness, blurred vision, etc., it is important to consider over-application of antihypertensive drugs. It is recommended to temporarily stop the use of antihypertensive drugs and gradually increase the use of antihypertensive drugs after the blood pressure has recovered. If the usual state of hypotension, low pressure is around 50 mmHg, not accompanied by dizziness, weakness, black eyes and other symptoms of hypotension, consider that it is caused by poor physical fitness, it is recommended to increase physical exercise, eat more nutritious substances, improve their physical fitness, and try to make the low pressure of blood pressure above 60 mmHg to meet the perfusion of the heart, brain and kidneys.
