Diastolic blood pressure of 50mmHg blood pressure is low, but if the corporal hypotension, no obvious symptoms, generally no need for treatment, if the pathology of low blood pressure, the need for hospital treatment. Generally speaking, systolic blood pressure below 90mmHg, diastolic blood pressure below 60mmHg blood pressure is low. However, if the diastolic blood pressure stays stable at 50mmHg for a long time without any uncomfortable symptoms, it may be the corporal hypotension, which is relatively common among thin women and the elderly, and does not need treatment. Some elderly people are prone to systolic blood pressure (high pressure) higher than 140mmHg due to arteriosclerosis, but diastolic blood pressure (low pressure) is not high, and there is no obvious discomfort, it is simple systolic hypertension, and you should consult a doctor for treatment of high blood pressure. For people with only mild symptoms of fatigue and tiredness, appropriate nutrition and physical exercise may be considered. If the daily diastolic blood pressure is above 60mmHg, and the diastolic blood pressure decreases to 50mmHg in a short period of time, accompanied by symptoms such as dizziness and darkness in front of the eyes, one should consult a doctor immediately. If the blood pressure is too low due to antihypertensive drugs, it is necessary to reduce the dose of antihypertensive drugs or replace other antihypertensive drugs under the guidance of the doctor; if a large number of body fluids are lost due to diarrhea, vomiting and other reasons, resulting in low blood pressure, it is necessary to replenish body fluids in a timely manner, and the oral rehydration salts are often used, which may cause nausea, vomiting and other adverse reactions. Diastolic blood pressure 50mmHg has many causes, if the patient dizziness, fatigue symptoms are serious, or the symptoms continue and have not improved, should go to the hospital in time for treatment.
