The hidden danger of low blood pressure

When people think of blood pressure problems, high blood pressure (hypertension) often comes to mind. But low blood pressure (hypotension), while less discussed, can be just as dangerous—especially when left unchecked.

Low blood pressure is generally defined as a reading below 90/60 mmHg. While some people may naturally have lower readings without symptoms, others may experience troubling effects like dizziness, fainting, blurred vision, nausea, fatigue, or even shock in severe cases.

One of the greatest risks is that low blood pressure can deprive the brain and other vital organs of adequate blood flow, potentially leading to confusion, falls, or even long-term damage in elderly individuals. It can be caused by dehydration, heart problems, blood loss, or side effects of medications.

In younger, healthy individuals, hypotension might not be a concern. However, when symptoms are present, it may signal an underlying issue that requires attention. For example, orthostatic hypotension—a drop in blood pressure when standing up—can be a warning sign of neurological or cardiovascular conditions.

Treatment often involves simple changes like drinking more fluids, adjusting medications, wearing compression stockings, or increasing salt intake (under medical supervision). But the key lies in recognition.

In short, don’t ignore low numbers on your blood pressure monitor. If you regularly feel lightheaded, weak, or faint, it’s time to consult your doctor. Low blood pressure may be quiet, but its effects can be serious.
