Auntie Wang is 57 years old this year.
Recalling the course of the disease, Aunt Wang was squatting in the yard and peeling corn kernels.
Clinically, it is not uncommon for Aunt Wang to have this situation.
The problem of blackening in front of the eyes is mostly here
In fact, the blackness in front of the eyes is a manifestation of cerebral ischemia
When the human body is squatting or sitting for a long time, the blood vessels of the lower extremities are compressed and the blood circulation is blocked.
For normal people, the body will immediately activate the blood pressure regulation mechanism at this time, speed up the heartbeat, strengthen the contraction of the heart, increase the blood pressure, send more blood to the whole body, and avoid insufficient blood supply
This kind of blood pressure drop when the body position changes and standing up quickly is called "orthostatic hypotension" in medicine
These people are more likely to get dizzy after squatting for a long time
Clinically, orthostatic hypotension is often screened by the supine-to-stand test
Generally speaking, people who are weaker, thinner, do not exercise for a long time, or are older are prone to orthostatic hypotension
Does "orthostatic hypotension" need medicine?
However, even if you belong to the above-mentioned vulnerable groups, don't worry too much
Slow down and change positions slowly, don't stand up suddenly, and give your body a little time to react
Keeping exercise and exercising more regularly can strengthen the blood pressure regulation ability in the body and reduce the risk of orthostatic hypotension
Regular work and rest should ensure adequate sleep every day to avoid staying up late and causing blood pressure fluctuations
Regular monitoring and timely medical treatment are recommended for middle-aged and elderly people to regularly monitor blood pressure in different positions at home
knock on the blackboard
If you stand up after squatting for a long time, your eyes will turn black, which is probably due to cerebral ischemia symptoms caused by orthostatic hypotension
Postural hypotension can be screened for by measuring supine and standing blood pressure at home
Change the position to slow down, do more exercise every day, develop normal work and rest habits, regularly monitor blood pressure, and seek medical attention in time if symptoms are found, which can avoid serious events such as syncope and falls caused by orthostatic hypotension
