What is the diagnostic criterion for hypotension?

Therefore, special attention must be paid in daily life, and one must understand the relevant criteria; otherwise, unnecessary consequences may arise. So, what is the diagnostic criterion for hypotension?

What Is the Diagnostic Criterion for Hypotension?

Hypotension is defined as a systolic blood pressure below 90 mmHg or a diastolic blood pressure below 60 mmHg. For patients with hypotension, the primary focus should be on actively identifying the underlying cause. In many cases, hypotension results from physiological or physical factors and currently requires no specific treatment. However, for severe pathological hypotension—such as that caused by heart failure, myocardial infarction, or shock—blood pressure should be promptly elevated to at least 90/60 mmHg.

This is because such pathological hypotension can lead to severe organ hypoperfusion; particularly under acute hypercoagulable states, it may even precipitate cerebral thrombosis due to low perfusion pressure. Physiological hypotension does not require specific treatment, whereas pathological hypotension necessitates targeted therapy based on its underlying cause. Physiological hypotension refers to chronically low but stable blood pressure—for example, a young woman whose baseline blood pressure consistently measures 88/60 mmHg (i.e., slightly low systolic pressure). This is relatively common and may occur even in individuals with no apparent physical weakness or health concerns.

Even in such cases of persistently low—but otherwise normal—blood pressure, if all other clinical parameters remain within normal limits and daily functioning is unaffected, this condition is classified as physiological (i.e., benign) hypotension. We hope this explanation proves helpful.
