Blood Pressure, Low Definition

Blood pressure, low (or low blood pressure) is the opposite of high blood pressure. Also known as hypotension, low blood pressure may not necessarily pose a health risk unless it is caused be an underlying medical condition.

Blood Pressure, Low Diagnosis

Low blood pressure can usually be determined through a blood pressure gauge. To identify the underlying cause, the following diagnostic methods may be used: blood tests, electrocardiogram, echocardiogram, stress test, valsalva maneuver, and tilt-table test.

Blood Pressure, Low Symptoms and Signs

Most individuals with low blood pressure are actually in peak physical condition with reduced risk of cardiovascular disorders. However, extremely low blood pressure can indicate the presence of an underlying problem, particularly when low blood pressure is accompanied by the following symptoms: lightheadedness or dizziness; fainting spells; nausea; inability to concentrate; pale and clammy skin; rapid and shallow breathing; fatigue; depression; and constant thirst. Severe hypotension may deprive the brain and other vital organs of oxygen and essential nutrients, causing the body to go into shock.

Blood Pressure, Low Treatment

Low blood pressure that occurs without accompanying symptoms does not require treatment. Therapy for symptomatic cases depends on the underlying cause. Treatment is focused on the primary health problem rather than on the blood pressure itself.
