The environment seems to be spinning, cold sweats are breaking out on the skin, and little stars are dancing in front of the eyes. Circulatory problems are a common symptom that often accompanies complaints like dizziness or nausea. Most of the complaints are caused by a low blood pressure (hypotension). But there are other causes that can be behind circulatory problems. We inform you comprehensively about the topic and give tips on what you can do to prevent circulatory problems.
Possible causes of circulatory problems
Circulatory problems are often triggered by low blood pressure. Low blood pressure is referred to when it falls below a value of 105 to 60 mmHG. Due to the low blood pressure, it can happen that the brain is no longer supplied with enough blood and thus enough oxygen. This can lead to symptoms such as dizziness, sweating or blackening.
However, in addition to low blood pressure, circulatory problems can have a number of other causes. This includes:
- infectious diseases
- Inflammations in the body
- Mental disorders
- Disorders of the metabolism (for example through diarrhea)
- Disorders of blood flow or blood pressure
- bronchial asthma
In addition, circulatory problems can also be caused by high blood loss, severe hypothermia, poisoning and drug abuse.
Low blood pressure as a cause
Depending on whether it is known which cause is behind the low blood pressure, one differentiates between a primary and a secondary hypotension.
In primary hypotension, the causes of the usually permanently low blood pressure are unknown. Young, slim women often suffer from such a primary hypotension - they get circulatory problems, among other things, at high temperatures, large temperature fluctuations or prolonged bed-rest.
Secondary hypotension, on the other hand, is known to trigger it. In the first place are diseases of the heart, the vessels or the nervous system as well as hormonal disorders. Such disorders can cause the blood to return to the heart or disrupt cardiac output. In addition, certain medications can also lead to a drop in blood pressure and associated circulatory problems.
Circulatory problems as a symptom of low blood pressure
Low blood pressure can either be acute or chronic. Symptoms associated with chronic low blood pressure include listlessness, rapid fatigue, dizziness, and loss of appetite. Furthermore, weather sensitivity, inner restlessness, an increased need for sleep, increased irritability and depressive moods can be felt.
Acute hypotension is triggered by a sudden, sharp fall in blood pressure. Typical symptoms of acute hypotension include sweating, dizziness, eye flutter and fainting. Such an acute drop in blood pressure may be caused, for example, by orthostatic hypotension.
In orthostatic hypotension - also known as orthostatic dysregulation - the adaptability of the blood pressure to the upright body position is disturbed. This can lead to circulation problems when getting up quickly from sitting or lying down. One cause of the discomfort is a malfunction of the venous valves in the legs, which in healthy people support the return of the blood to the heart.
However, orthostatic hypotension can lead to circulatory problems not only when getting up, but also in other situations. This is the case, for example, when standing in large crowds or in the blazing sun. Then it can cause symptoms like
- unsteady gait
- blurred vision
In the worst case, a circulatory collapse (fainting) is the result of a drop in blood pressure.
For frequent circulatory problems to the doctor
Occasional circulatory problems caused by low blood pressure are usually harmless. However, if you are more likely to have circulatory problems or are particularly violent, you should definitely consult a doctor - may be a disease requiring treatment behind the complaints.
