Definition
Suddenly standing up from a sitting or lying position may cause dizziness or blackness. This is due to a temporary reduction in the blood flow to the brain caused by the blood sinking into the veins of the legs and the resulting drop in blood pressure. One can distinguish different types of dizziness, among others rotary vertigo or swindling vertigo.
What forms of vertigo are there?
Vertigo can be divided into different forms. These are the most common: the sinking of blood into the veins of the legs and the resulting low blood pressure is to a certain extent common when changing position. However, this should trigger a reaction in the body that causes an increase in activity of the autonomic nervous system, more precisely of the sympathetic nervous system.
This ensures that the drop in blood pressure is contained. Furthermore, the heart rate increases so that the sufficient blood supply to the organs is maintained. However, if the body’s reaction is not sufficient, the insufficient blood pressure can cause complaints.
Symptoms would be dizziness, ringing in the ears or blackening of the eyes. If this occurs, one speaks of a so-called orthostatic dysregulation. and symptoms of low blood pressure
- Attack deception
- Permanent fraud
- Vertigo with hearing disorders
- Swindling
- Positional vertigo
- Dizzy feeling
Associated symptoms of dizziness when getting up
Nearly everyone knows it and has experienced it himself at least once: getting up too suddenly from a lying or sitting position makes you dizzy. Accompanying the dizziness often occurs a blackening before the eyes or eye flickering. These symptoms are typical of so-called “orthostatic dizziness”, which is caused by a sudden drop in blood pressure when changing position.
Due to the rapid rising, the blood sinks into the legs and cannot be transported from there quickly enough against gravity back to the heart. As a result, the blood pressure drops rapidly and the brain receives too little oxygen for a short time. In order to compensate for the drop in blood pressure, the heart beats faster and those affected have palpitations.
The sympathetic nervous system is also activated. The sympathetic nervous system puts the body on alert and ensures that blood pressure rises again by narrowing the blood vessels. Other typical signs of circulatory decline are therefore sweating and ringing in the ears. In rare cases, a very strong drop in blood pressure can also lead to brief fainting fits (syncope).
