Understanding Low Blood Pressure Readings

Mar 26, 2008
Understanding the difference between low blood pressure readings ( hypotension) and high blood pressure (hypertension) can be confusing, the two medical terms sound very similar. Although they are complete opposites both have serious medical consequences.

The autonomic nervous system controls your blood pressure using a vast network of hormones, receptors and nerves to control the sympathetic nervous system ( increases blood pressure) and your parasympathetic nervous system (lowers blood pressure) these two systems work together to constantly control your blood pressure while exercising or resting.

What Are Some Of The Triggers

The three main triggers, or causes for low blood volume. Hypovolemia is by far the most common and is simply reduced blood flow. The cause of reduced blood flow can result from many different events such as massive blood loss or hemorrhage, or something as simple as not consuming enough fluids and even persistent diarrhea can create reduced blood volume. Another possible answer is extended use of diuretics which cause the body to expel larger amounts of body fluid through urine than would normally take place.

There are 2 prime triggers, or causes, of low blood pressure readings. The most prevalent trigger is reduced blood volume, and can have various causes. Massive blood loss through injury is number one. Persistent diarrhea or Not drinking enough fluids, vomiting can lead to reduced blood volume.

The third trigger for low blood pressure readings is decreased cardiac output. Usually caused by some type of heart failure. This trigger for hypotension can produce cardiogenic shock caused by a lack of blood circulation. Arrhythmias, or an irregular heartbeat, the electrical activity of the heart is irregular or is faster or slower than normal, and may cause cardiogenic shock.

Some types of commonly prescribed medicines are Beta Blockers which lower blood pressure by slowing the heart rate or beats of the heart. This is why talking honestly with your doctor about the medicines you are taking is so important.

Postural hypotension and orthostatic hypotension are the most common types of low blood volume. In Orthostatic hypotension the decrease in pressure occurs with rapid changes in body position such as standing up quickly from a seated position and is usually temporary, and most commonly caused by low blood volume.

A simple blood test can determine many problems ranging from Anemia to low blood sugar. Other tests will reveal many problems lying dormant with your heart or cardio vascular system. To read more information about low blood pressure readings click the link below.
