A high pressure of 152 and a low pressure of 105 are not normal. The latest diagnostic criteria for hypertension in 2021 are systolic blood pressure greater than or equal to 140 mmHg and/or diastolic blood pressure greater than or equal to 90 mmHg measured three times on non-same day without the use of antihypertensive drugs. Hypertension is categorized into primary hypertension and secondary hypertension. Age, heredity, obesity, alcohol consumption, high salt diet, mental stress, etc. can cause primary blood pressure increase. Adrenal adenoma, renal artery stenosis, endocrine hormone abnormalities, etc. can cause secondary hypertension. It is recommended that patients monitor their blood pressure regularly, and if repeated monitoring reveals that the blood pressure is abnormal or accompanied by uncomfortable symptoms, they should consult a doctor in a timely manner to clarify the cause of the disease and receive timely treatment.
