Anemic syndrome is a description used for symptoms that occur by anemia. It is a consequence of the lack of hemoglobin (blood protein contained within red blood cells which is able to transport oxygen) leading to disruption of oxygen supply to tissues. An individual with anemic syndrome is therefore pale (pale skin and mucous membranes like in conjunctiva), tired and lethargic. A feeling of coldness is often present as well as dizziness, fainting, shortness of breath and palpitations by physical exercise. That is because increased activity of the heart which tries to supply tissues with oxygen. Further information can be found in more extensive text dedicated to anemia.
