Hypotension: When blood pressure is too low


Some people naturally suffer from low blood pressure. However, when hypertension suddenly becomes hypotension, it can be cause for concern.

Hypotension can be a sign of good health and a reduced risk of heart disease. But it’s not always the case. Sometimes persistently low blood pressure or a sudden drop in blood pressure can lead to worrying symptoms and even serious health problems.

What is hypotension

A blood pressure reading consists of two numbers: the systolic pressure and the diastolic pressure. Systolic pressure is the first number of your blood pressure. It shows the pressure in your arteries as your heart pumps blood. The diastolic pressure is the bottom number. It shows the pressure in your arteries when your heart fills with blood.

If your blood pressure is at or below 120/12 millimeters of mercury (mm Hg), it is considered normal . In general, if the blood pressure is lower than 90/60 mm Hg, it is abnormally low and we then speak of hypotension. Some adults regularly have low blood pressure but have no symptoms and do not need treatment. In severe cases, however, hypotension can lead to decreased oxygen and nutrient delivery to the brain and other vital organs. This can eventually have serious consequences.

Anyone can develop hypotension, but certain groups of people are more likely to suffer from it. There are different types. For example, orthostatic (positional) hypotension, which occurs when you get up from sitting or lying down, is more common in older people. In general, your body has some compensating mechanisms to prevent your blood pressure from dropping when you stand up. But, orthostatic hypotension is a problem for some people because these reflexes that should happen, don’t happen. Dehydration or blood loss can also cause orthostatic hypotension.

Symptoms of hypotension

Most doctors do not consider low blood pressure as a problem, unless associated with certain signs and symptoms:




Concentration problems

A Blurred vision


Pale clammy skin

Shortness of breath

What is a dangerously low blood pressure number?

It doesn’t There is no precise figure from which the daily blood pressure is considered too low. However, when low blood pressure is accompanied by any of the dangerous symptoms listed above, it’s time to see a doctor.

When can low blood pressure strike?

Some people have naturally low blood pressure, and have no symptoms. But for those who are used to having high blood pressure, a sudden drop in blood pressure can signal a problem and cause the symptoms listed above.

An episode of low blood pressure is more likely to occur under these conditions:

– Resuming an upright posture after a long bed rest

– Being in the 29 first weeks of pregnancy

– Loss of a large amount of blood

– Being dehydrated

– Taking of certain medications. Such as drugs to lower blood pressure, drugs for the heart, drugs for Parkinson’s disease, tricyclic antidepressants or drugs to treat erectile dysfunction.

– Having a heart problem, such as a very slow heartbeat, heart valve problems, heart attack or heart failure

– An endocrine problem, such as hypothyroidism, parathyroid disease, Addison’s disease (an adrenal gland disorder), low blood sugar, or diabetes

– A serious infection that gets into your blood

– Anaphylaxis, a life-threatening allergic reaction

-Having a neural disorder that affects your blood pressure

-Having a nutrient deficiency, for example low vitamin B

Can low blood pressure make you tired?

Hypotension can cause fatigue. A feeling of overwhelming fatigue and lack of energy. There is a link between hypotension and chronic fatigue syndrome, a condition characterized by profound fatigue, pain and sleep disturbances that are often aggravated by exertion.

There is no There is no cure for this type of fatigue. But doctors may suggest treating underlying causes, such as trouble sleeping or mental health issues. Treating low blood pressure with changes in diet and appropriate physical activity can also help.

When do you need medical attention for low blood pressure?

If your blood pressure is still low and you don’t have any of the dangerous symptoms, there is usually nothing to worry about. Likewise, if you have a single home blood pressure reading that is abnormally low without any symptoms, you probably don’t need to see your doctor. It is normal for your blood pressure to rise and fall over time. Your body is usually able to bring it back to normal.

But when you feel there is a recurring problem, or there is no clear explanation for what happened, you need to see a doctor. If your blood pressure suddenly drops and you experience symptoms such as dizziness, it’s time to consult.

Immediate measures in the event of a drop in blood pressure

The treatment of hypotension will depend on the cause of the hypotension. Immediate actions may include the following:

    lying down with feet above heart

  • Drink Water

  • Avoiding Triggers hypotension such as prolonged standing
  • After evaluation, a doctor can make these recommendations:

  • Avoid alcohol.
  • Adjust your diet.

    Adapt your medications (possibly by reducing the doses of medications that lower blood pressure).

  • Take medication that increases blood pressure
  • Wear compression stockings.
  • People who experience a drop in blood pressure will need emergency treatment to restore blood flow to their organs and bring their blood pressure back to normal. It is important to determine whether your low blood pressure is “a primary or secondary problem.” A primary problem means that the body’s reflexes are not working as they should. Secondary causes mean that low blood pressure is the result of things like dehydration or the effects of certain medications.

    Keep track of your blood pressure readings. Even if you don’t have any health issues. This is to find out what your personal normal measurements are. And if your blood pressure is being monitored, ask your doctor what target blood pressure range is best for you.
