Postural hypotension is blood pressure instability caused by mechanical reasons, not hypotension. After we squat down, the blood vessels in the legs will contract, and the blood circulation in the legs will not be smooth, so we can't participate in the blood circulation of the whole body quickly. When we suddenly stand up, the blood in the upper body will quickly circulate to the lower limbs, leading to blood loss in the head and dizziness.
The second reason is low blood pressure.
In fact, hypotension is not a disease, but it is also a disease, because hypotension can cause many diseases, especially vascular diseases. Hypotension leads to systemic blood circulation compensation, and the heart will be affected to some extent.
The most uncomfortable thing is poor blood circulation for a long time, which leads to head ischemia and often dizziness. Then there is slow response, frequent fatigue and fatigue, and you can't do too tired work to avoid physical discomfort. Hypotension does not need drugs or surgery, but can be adjusted through food supplement and routine, so as to achieve stability and rehabilitation.
The third reason is anemia.
Anemia has many sources, mainly the uneven number of different cells or the "blood disease" caused by some cells. Anemic people are sallow or pale, giving people a feeling of malnutrition, which is caused by the different distribution of blood cells in the body. Deficiency of qi and blood can make people look unbalanced. Anemia causes blood not to flow to the brain normally, which leads to dizziness.
The fourth reason is arrhythmia, cervical spondylosis and brain diseases.
Arrhythmia, cervical spondylosis, brain diseases and other diseases are not trivial matters, and the symptoms of these diseases are obvious. If you often feel dizzy and your eyes are uncomfortable, you must go to the hospital for diagnosis, instead of simply thinking that you are postural hypotension. For example, arrhythmia can easily lead to shortness of breath and difficulty breathing. For example, cervical spondylosis can easily lead to long-term head ischemia and brain diseases. More serious cases may lead to paralysis of the upper part of the head, and brain diseases can not be ignored.
