Hypotension is a condition that appears when an individual's blood pressure (the pressure from the blood against the blood vessels walls) is lower than normal.
This situation can cause the so called "low blood pressure symptoms", which include:

• Dizziness, or feeling of losing balance
• Fainting
• Nausea
• Rapidly becoming pale and feeling cold
• Difficulty concentrating, feeling anxious, feeling confused
• Change of breathing patterns

As you can see, hypotension has easily recognizable symptoms, unlike high blood pressure which goes unnoticed most of the time.
These signs and symptoms appear when the pressure of the blood is at a fairly low point, and they are a signal from our body that we need to check our health.
A visit to a doctor is important to determine the underlying causes and follow proper treatment.
If you experience sudden fainting and permanent dizziness, you should go to a doctor immediately, and emergency should be called if you present various symptoms at the same time, including vomiting and chest pain.
Sudden drops of low blood pressure levels, doesn't require being on low levels for symptoms to start developing.
In these cases the symptoms appear quite rapidly and with a reason - when there are sudden drops of pressure we are at risk and need medical attention.
This rapid change can occur for example as a consequence of blood loss or severe trauma.
It is important to get to know all the mentioned symptoms of low blood pressure, because it will help us react better to possible problems.
