Some anemia patients also have functional heart murmurs. The doctor hears a heart murmur with the stethoscope while the heart pumps the blood, but this usually disappears as soon as the anemia has been resolved and there are no heart murmurs due to other diseases.
The stress on the heart can range up to heart failure. Characteristics are shortness of breath (Dyspnea), Water retention (edema) and nocturnal urination (Nocturia). Initially, the shortness of breath only shows up during exertion, in the advanced stage also at rest.
