Low Blood Pressure: What's Considered Too Low?

Generally, a blood pressure reading below 90/60 mmHg is classified as hypotension, or low blood pressure. In some cases, individuals may naturally have lower blood pressure due to genetic factors or general constitution. When this occurs without any symptoms or underlying conditions, it typically doesn't affect life expectancy and may only require regular monitoring.

Understanding the Causes of Low Blood Pressure

When low blood pressure is caused by serious medical conditions—such as severe trauma leading to hemorrhagic shock, advanced heart failure, or other critical illnesses—prompt medical intervention is necessary. Treatment in these cases focuses on addressing the underlying condition while also managing blood pressure to stabilize the patient's health.

Orthostatic Hypotension: A Special Case

Some individuals may experience a sudden drop in blood pressure when changing positions, especially when standing up from a seated or lying position. This condition, known as orthostatic hypotension, can lead to symptoms like dizziness, lightheadedness, or even fainting. Identifying the root cause is essential for effective management.

Orthostatic hypotension is often linked to issues such as autonomic nervous system dysfunction, dehydration, or certain medications. In more complex cases, it may also be related to structural problems like arterial malformations or heart valve disorders. Patients experiencing frequent symptoms should consult a healthcare provider for a thorough evaluation and personalized treatment plan.
