What is the standard value for hypotension?

Low blood pressure is less common in clinical practice than hypertension, yet its health risks are no less serious. Over the years, clinicians have increasingly identified cases of low blood pressure—indicating that it is posing a growing threat to public health. So, what constitutes the diagnostic threshold for low blood pressure?

What Is the Diagnostic Threshold for Low Blood Pressure?

The generally accepted threshold for low diastolic blood pressure is 60–90 mmHg. Currently, in China, a diastolic pressure range of 60–90 mmHg is considered acceptable. However, strictly speaking, the normal diastolic range should be 60–80 mmHg, with most healthy individuals falling between 70–80 mmHg. As long as diastolic pressure remains within 60–90 mmHg, it is regarded as normal and typically requires no specific intervention. A diastolic pressure consistently exceeding 90 mmHg is classified as hypertension, whereas a sustained diastolic pressure below 60 mmHg indicates hypotension.

To prevent hypotension, patients should move slowly and deliberately, and avoid excessively hot or cold water when bathing. In daily life, regular physical exercise is recommended to enhance the body’s autoregulatory capacity. Patients prone to micturition-induced hypotension should hold onto a stable object while urinating. Nutritionally, patients should consume foods rich in protein, iron, copper, folic acid, and vitamins—such as pork liver, egg yolks, lean meat, milk, soybeans, and brown sugar.

Patients are advised to maintain a light, balanced diet and engage in regular physical activity to improve overall physical fitness. We hope this information proves helpful.
