6-Rapid heartbeat
The heart has impressive machinery that is automated to execute its functions and maintain the body in an optimal state. It detects low energy levels and low pulse that is common in anemic patients and tries to rebalance the problem by increasing the heartbeat to make up for the deficiency. Patients with anemia that is secondary to blood loss have a severe reduction in the circulating volume of blood, and the heart detects this alteration and tries to provide more oxygen to the body by moving faster the volume of blood that is left, thus leading to a rapid heartbeat.
