Will blood pressure be too low?

Many Americans are so used to hearing about the dangers of high blood pressure that they may not have considered an alternative: low blood pressure.

To be fair, if they were faced with a choice, they would rather have the smaller blood push against the walls of their arteries than the larger blood. Even pompous sources like the American Heart Association say, “Within a certain range, the lower your blood pressure reading, the better.”

But as you might guess, there are exceptions.So take a cue from doctors who tend to look at hypotension in a factual way: only when symptom become a problem.

This article explains what low blood pressure is, its symptoms and causes, and how it is usually treated.

Why low blood pressure is important

For most adults, a healthy blood pressure is 120/80 mmHg, while low blood pressure (also called hypotension) is less than 90/60 mmHg. In contrast, prior to November 2017, high blood pressure or elevated blood pressure (also known as hypertension) was defined as 140/90 mmHg or higher. The American College of Cardiology and the American Heart Association then lowered the standard to 130/80 mmHg or higher.

Some people have low stress and feel good. In fact, they may not even know they even have low blood pressure until they get their stress test at the doctor’s visit. It’s a moment of reckoning like this, or the presence of overt symptoms that make low blood pressure a problem that should be addressed.

symptoms of low blood pressure

Some people may have mild symptoms of low blood pressure. They may feel tired, dizzy, confused or weak. They may even experience blurred vision, headaches, neck or back pain, or nausea. But sitting down may be all they need to do to feel like themselves again.

The real problem with low blood pressure is that vital organs may not be getting all the oxygen and nutrients they need. In this case, the low pressure causes the shock. These signs include:

  • blue skin tone
  • cold skin
  • shortness of breath, shallow breathing
  • Weak or fast pulse

Shock requires immediate medical attention, so call 911 immediately.


Shock is a serious consequence of hypotension. Call 911 if you have blue skin, cold and sweaty skin, shortness of breath, shallowness, or a weak or fast pulse.

Another problem with low blood pressure is that symptoms vary from person to person. Symptoms occur when blood pressure drops so low that blood flow to the organs is compromised. In addition to the symptoms above, please contact your healthcare provider if you experience:

  • Dizziness
  • dehydration and excessive thirst
  • decreased urine output
  • syncope
  • inattention

Causes of low blood pressure

If you feel these symptoms for an extended period of time—say, for a few days—your healthcare provider may want to look for the underlying cause. A treatment plan may depend on it. A variety of conditions can cause chronic low blood pressure, including:

  • Allergic reactions (severe allergic reactions)
  • prolonged bed rest
  • certain drugs
  • blood loss resulting in decreased blood volume
  • endocrine status
  • heart problems
  • Infect
  • Nutritional deficiencies (such as a lack of vitamin B-12 or folic acid)
  • pregnant

keep a record

To help your provider make an accurate diagnosis, keep a record of your symptoms and what you did when your symptoms occurred.

treatment solutions

In healthy people, low blood pressure may not require any treatment. Again, all attention will be on your symptoms. However, your healthcare provider may tell you to sit or lie down before raising your feet above your heart level. The provider can then:

  • If the drug is the suspected cause, change the dose or suggest an alternative. Do not stop taking any medications until you speak with your provider.
  • If you are dehydrated, it is recommended to drink plenty of water.
  • It is recommended that you wear compression stockings, which help prevent blood from pooling in the legs and encourage blood to travel to the upper body.

Severe hypotension due to shock is a medical emergency and you may get:

  • Blood drawn by needle (IV)
  • Medications that increase blood pressure and strengthen the heart
  • other medicines, such as antibiotics

be optimistic

Treatment of low blood pressure is usually very successful.


While a healthy blood pressure is 120/80 mmHg, many people have the opposite: low blood pressure, below 90/60 mmHg. Many people live with low blood pressure without even knowing they have it. They may often feel tired, dizzy or weak, but do not link these symptoms to a disease. If these symptoms persist or escalate into a more serious event, it’s time to consult your healthcare provider. In the worst case, low blood pressure can lead to shock, a medical emergency.

VigorTip words

From the American Heart Association: Unless you’re experiencing other symptoms or problems, a single subnormal blood pressure reading is no reason to panic. Try sitting down, take a few deep breaths, and raise your feet to heart level or above. Then read it again. Like temperature readings, blood pressure readings can vary, so let your symptoms guide your next steps.
