What level constitutes hypotension?

Many individuals suffer from hypotension due to malnutrition. In fact, if hypotension is severe, it can significantly impair daily life and academic performance—and adversely affect work productivity as well. Therefore, prompt treatment is essential upon diagnosis of hypotension. Since numerous factors can cause hypotension, what blood pressure values constitute hypotension?

What Constitutes Hypotension?

Generally, hypotension is defined as a systolic (upper) blood pressure below 90 mmHg and a diastolic (lower) blood pressure below 60 mmHg. However, some elderly individuals may have baseline blood pressures not lower than 90/60 mmHg; yet, due to antihypertensive medications or conditions such as orthostatic hypotension, they may suddenly experience dizziness, fatigue, visual darkening (e.g., “blackout”), chest tightness, or shortness of breath during physical activity. In such cases, even if the measured blood pressure remains above 90/60 mmHg, it is considered clinically low relative to the individual’s normal range—thus qualifying as hypotension.

Following onset of hypotension, symptoms often improve through lifestyle modifications and traditional Chinese medicine (TCM) therapy. Additionally, elderly patients with orthostatic hypotension should rise slowly from lying, sitting, or squatting positions to prevent falls and potential serious injury. If hypotension persists over time, medical evaluation is recommended to rule out underlying diseases. In daily dietary practice, increasing intake of salt and protein-rich foods—as well as maintaining adequate hydration—can help expand intravascular volume and thereby support improved blood pressure regulation.

In everyday life, maintain regular, balanced meals; avoid spicy, stimulating, or overly rich foods; refrain from binge eating; and ensure sufficient sleep by avoiding late-night activities. We hope this information proves helpful.
