Patient's question:
My complexion is particularly bad, giving others the impression that I always look unhealthy. Even after working for several years, my face is still always pale. At work, colleagues often ask if I'm sick, and sometimes I even experience acute blood loss or even shock.Doctor's answer:
Hello, acute hemorrhagic anemia is caused by trauma or diseases leading to blood vessel rupture, or by coagulation and hemostasis disorders, resulting in a significant loss of blood within a short period. This not only affects blood volume but also causes anemia after acute blood loss, with initial iron stores remaining unchanged. When the bleeding amount increases to 1500-2000 milliliters (approximately 40% of total blood volume), even if the patient is very healthy before bleeding and rests in bed afterward, they may still experience thirst, nausea, shortness of breath, severe dizziness, or even brief loss of consciousness.
