A high pressure of 105mmhg and a low pressure of 69mmhg are considered normal blood pressure. It is recommended that blood pressure should be measured several times to avoid missing the diagnosis due to accidental errors. Normal blood pressure systolic blood pressure should be 90~120mmHg, diastolic blood pressure should be 60~80mmHg, so the blood pressure 105/68mmHg is normal blood pressure. Diagnosis of hypertension requires multiple measurements of blood pressure, measurement of three blood pressure non-same day, systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg. Hypertension cannot be diagnosed based on a single blood pressure value, and should be measured multiple times. In daily life, one should quit smoking and limit alcohol, try to avoid a diet high in oil and salt, it is recommended to eat less than 6 grams of salt per person per day, and eat less food with high salt content such as pickled food. Eat more fresh vegetables and fruits. If there are symptoms of dizziness and other discomforts, you should seek immediate medical examination.
