When Is Low Blood Pressure Too Low? Hypotension And More


In the human body, the regulation of blood pressure is one of the most important processes that take place.

The heart is responsible for pumping blood and the arteries take it to different body parts.

If there is any kind of disturbance in this series of events, the body might stop functioning normally.

As far as blood pressure measurement is concerned, the normal value is 120/80 for a healthy human being. There are two types – diastolic and systolic.

These are dependent upon the movement of blood to and from the heart respectively. The former is non-oxygenated blood while the latter is oxygenated. 

Causes Of Too Low Blood Pressure

Not all values below 120/80 are considered to be low blood pressure.

Causes Of Too Low Blood Pressure

When there is a huge imbalance, low blood pressure is considered too low for a normal human being. This might happen because of the following reasons – 

Genetic Issues

If adults in the family are suffering from chronic low blood pressure, it is quite common to suffer from the same in the next generation.

Regular checkups will help in regulating the same. 

Heart Disease

People who have undergone heart surgery at some point in time might have issues of regulating their blood pressure.

Other factors like using a pacemaker or suffering from heart holes further aggravate the situation of low blood pressure. 

Sudden Change Of Temperature

At times, suddenly moving from a warm to a cold climate and vice versa might have an adverse effect on blood pressure.

The heating mechanism of the body gets affected to a considerable extent and thus, the functioning of the heart is hampered.

This in turn leads to a sudden drop in blood pressure. Another common occurence in such a situation is missed pulse. 


When the body loses its fluids, a lot of pressure is applied to the heart to make up for the loss.

While trying to make amends, the heart muscles give in at times and thus, the situation goes up to drop in blood pressure levels.

This can easily be cured by taking up enough fluids and resting for an adequate amount of time to replenish the normal working condition of the heart as well as the body. 


The drugs used to control high blood pressure might have the opposite effects at times.

If taken continuously for a prolonged period of time, these medicines might lead to a sharp drop in blood pressure which might become really difficult to manage.

Thus, it is advisable to have routine checkups when taking medicines to control high blood pressure, irrespective of age.  

What Is Hypotension?

When the blood pressure falls below 90/60 on the measuring scale, this is known as hypotension.

With time, hypotension may lead to other health issues like nervous system damage.

The person might faint on the spot and become unconscious for an elongated time period.

In addition to this, there is a high chance of over-sweating followed by vomiting.

If not checked on time, hypotension might turn fatal and lead to partial or permanent paralysis as blood supply to far-off body parts might be cut off.

Shivering in the legs is also a common occurrence. It is worth noting that the heart pumps blood to the brain against gravity which requires a lot of strength.

On the other hand, the feet are the farthest from the heart and thus, too low blood pressure can most easily be spotted from a tingling sensation in the feet which progresses with time.

Whenever you feel that your blood pressure levels are fluctuating, it is best to get the same checked at the earliest.

In addition to regular checks, one must also take care of the lifestyle habits which make the blood pressure drop beyond manageable levels.

On the other hand, taking stress about low blood pressure might further worsen the condition of the body.

This is then known as hypertension or high blood pressure.

Aim at maintaining normal blood pressure and range. This is not a very serious issue and can be solved quite easily if addressed on time.
