What is the term for abnormally low blood pressure?

The term for abnormally low blood pressure is hypotension. This condition refers to blood pressure readings that are lower than the normal range, which is typically defined as systolic pressure below 90 mmHg and diastolic pressure below 60 mmHg. Hypotension can lead to symptoms such as dizziness, fainting, and fatigue, as insufficient blood flow may prevent organs and tissues from receiving adequate oxygen and nutrients.

In the context of the other terms: hypertension is the opposite of hypotension, referring to abnormally high blood pressure. Orthostatic hypotension is a specific type of hypotension that occurs when a person stands up from sitting or lying down, resulting in a sudden drop in blood pressure. Elevated BP is a vague descriptor that does not specifically define low blood pressure, as it implies heightened blood pressure levels rather than the low readings that characterize hypotension. This understanding of the terms is essential for recognizing and addressing varying blood pressure conditions effectively.
