If the hypertension and hypotension of blood pressure are both low, lower than 90/60mmHg belongs to hypotension. Hypotension is mainly seen in three situations, including physiological hypotension, primary hypotension and secondary hypotension. Physiological hypotension is a physiological state. Although the blood pressure is low, the patient has no symptoms, does not affect health, does not affect life, and does not need special treatment. Primary hypotension, also known as constitutional hypotension, is commonly seen in the elderly and women with weak physique. Secondary hypotension is often secondary to related diseases, including acute secondary hypotension and chronic secondary hypotension. Acute secondary hypotension is often secondary to acute myocardial infarction, massive blood loss and shock caused by various reasons, while chronic secondary hypotension is often secondary to malignant tumors, chronic tuberculosis and severe malnutrition.
