If they do not receive timely treatment, as the amount of blood loss increases, they will become pale, weak, dizzy, weak, have memory loss, and even have blurred vision and tinnitus. Suddenly standing up after sitting or squatting for a long time may lead to collapse or fainting. In severe cases, there is a decrease in appetite, abdominal distension and lower abdominal edema.
