Circulatory weakness is classically accompanied by various symptoms: those affected become “black before their eyes”, they feel a more or less pronounced feeling of dizziness, their ears rush, they sweat even though their feet are often cold, in general they feel dazed and occasionally headaches are added to the symptoms. These symptoms of circulatory weakness occur mainly when you move from a lying down to an upright position, typically for example in the morning after getting up. When you stand up, a large part of the blood is lost in the capacity vessels, i.e. the veins of the legs.
As a result, less blood is returned to the heart, which means that less blood can be pumped to the brain. Since the blood is the oxygen carrier in our body, the brain is supplied with too little oxygen for a short moment. This leads to the corresponding symptoms of circulatory weakness.
In order to normalize the blood circulation, the heart increases its beat frequency reflexively to compensate for the resulting lack of volume. For this reason, many patients also experience palpitations as a complaint. In severe cases, especially when the blood pressure drops very rapidly and sharply, fainting can occur: The affected person suffers a collapse and falls to the ground.
However, the problem is, so to speak, no longer a problem because the horizontal positioning of the body ensures improved blood circulation in the heart. Consequently, the affected person recovers quickly and the unconsciousness is only of very short duration. Symptoms of circulatory weakness, which are not only acute but can be generalized to circulatory weakness, are caused by the body activating the sympathetic nervous system, the component of the nervous system that puts the body in an active state that enables it to perform at its best in the event of a fight or flight.
This leads to an increased heart rate, i.e. a high pulse, insomnia and sweating. Due to the fact that the parts of the body far away from the heart in particular are not supplied with sufficient blood, those affected very often have cold hands and feet.
