It is well known that high blood pressure is a serious problem that puts us at risk of suffering from a good number of cardiovascular diseases, including some that are potentially lethal. However, many people are unaware that the opposite, having the tension excessively lowIt also carries certain risks.

When do we consider it to be too low?

Too low a voltage is called arterial hypotension. As a general rule, it is considered as such when the systolic pressure (at the time of the heartbeat) is less than 90 millimeters of mercury (mm Hg) and the diastolic pressure (in the interval between heartbeats) is less than 60 mm Hg, as as collected by the National Library of Medicine of the United States.

However, it is important to note that optimal blood pressure is actually varies between individuals, depending on their particular characteristics and factors such as age or sex. Therefore, there are people who consistently mark values ​​considered as hypotension, but do not experience any symptoms.

That said, hypotension can also be the result of different clinical events or even in some people from postural changes, which is called orthostatic hypotension. Thus, hypotension is only considered pathological when it causes symptoms.

What symptoms and complications does it cause?

According to the prestigious Mayo Clinic American, when arterial hypotension produces signsThese may include some such as blurred or diminishing vision, dizziness or lightheadedness, fainting, fatigue, difficulty concentrating, and nausea.

If the values ​​are extremely low, hypotension can trigger a serious condition known as shock. In this case, characteristic signs include confusion, clammy skin, paleness, rapid shallow breathing, and a rapid, weak pulse.

The shock supposes a significant decrease in blood flow throughout the body, with the consequent insufficiency in the supply of oxygen to the cells. Therefore, if it is not addressed in time, it can end up causing permanent organ damage or even death.
