If Your Vision Goes Dark When You Stand Up — Before Anemia
의료 감수 Dr. Heo Ji-young Representative Director · KMD
If your vision goes dark when you sit and then stand up, there is something to check before anemia.
Anemia is confirmed by a blood test. But if your blood counts are normal and yet you feel dizzy every time you stand up, it may be an autonomic problem — the inability to regulate blood pressure quickly when your posture changes.
- The tests say it isn't anemia, but you keep feeling dizzy
- It's worse when you stand up from sitting, or when you stand for a long time
In cases like these, we need to look together at both blood pressure regulation and circulation.
