We get so used to hearing about the signs and dangers of hypertension (high blood pressure) that we may falsely believe that low blood pressure is then conversely healthy. Blood pressure is the most healthful when properly regulated and within a small range where there is enough pressure to fully pump blood throughout the body and back to the heart and yet not so much that it adds tension to the veins, capillaries, arteries, veins, and organs.

As a general guide, the ideal blood pressure used to be considered 120/80. Recently, in 2019 the AMA (American Medical Association) has updated its recommendation, lowering it. The ideal is now considered to be between 90/60mmHg and 120/80mmHg.

Hypotension (low blood pressure) would be anything that regularly tests below 90/60mmHg.

For some people having low blood pressure may remain asymptomatic, causing no problems, but for others, especially those with severely low pressure it can be dangerous and even life-threatening.

Causes can range from medical issues to dehydration, to surgical disorders. Finding the cause is vital for proper treatment.

How to detect low blood pressure – Know the signs

• Fatigue
• Inability to concentrate
• Nausea
• Dizziness
• Lightheadedness
• Fainting

Even more severe symptoms may include signs of shock:

• Weak pulse
• Rapid pulse
• Cold clammy hands
• Paleness
• Confusion
• Shallow breathing

If you have signs of possible hypotension its important to check your blood pressure immediately. If it is below 90/60, especially by a lot, and you do not feel well, please see your doctor asap. A change of just 20 mm hg can cause you to faint and falling can be hazardous. Severely low blood pressure can deprive your body of oxygen. Oxygen is needed to carry out its normal functions. This lack can quickly lead to damage of your heart and/or brain.

Possible Medical Causes of Low Blood Pressure:

• Heart problems
• Pregnancy
• Endocrine problems
• Dehydration
• Blood loss
• Infection
• Malnourishment
• Severe allergic reaction

Certain medications may also cause low blood pressure. Water Pills, Alpha Blockers, Beta Blockers, Parkinson’s Disease Drugs, Antidepressants, and Drugs for Erectile Dysfunction all can cause a drop in pressure.

Keeping your blood pressure in check is important. Though a single reading out of range does not mean you need medical help or have a problem repeated out of range readings, either low or high, it should be cause for alarm. Talk to your doctor about how to help control your blood pressure.
