Anemia Symptoms; What Are the Symptoms of Anemia?


Anemia is a condition in which the blood running through your veins contains significantly fewer red blood cells than it should. Red blood cells, also called erythrocytes, are the most plentiful blood cell type in your body and the principal mechanism through which the various organs and tissues receive the necessary hemoglobin for normal function.

Hemoglobin is a type of protein which fulfils the crucial role of transporting oxygen throughout the body, thus ensuring that it has enough energy to power the multitude of metabolic processes necessary for life.

Therefore, when insufficient red blood cells populate the blood supply, hemoglobin becomes scarce and, subsequently, metabolic function breaks down on a multitude of levels. As a result, Anemia manifests with an extensive set of symptoms which carry with them varying degrees of severity.

Anemia may be classified into three categories depending on the mechanisms behind the decreased supply of red blood cells. These are:

  • Blood Loss
  • Impaired production of red blood cells
  • Increased destruction of red blood cells

Acute Posthemorrhagic Anemia
Or Anemia caused by sudden blood loss

Under conditions of significant blood loss, the human body begins to rapidly absorb water from various tissues into the bloodstream to ensure that blood vessels retain sufficient pressure. Consequently, blood is diluted, and the percentage of red blood cells in the bloodstream decreases dramatically.

Two things occur when this happens. First, blood pressure drops dramatically, and the body’s oxygen supply is severely compromised. As a result, the following symptoms begin to quickly manifest.


Can be described as a sensation of insufficient energy, exhaustion, or fatigue. Weakness due to sudden blood loss can dramatically impact cognitive functions and cause loss of memory, difficulty paying attention, difficulty concentrating, and staying vigilant. If blood loss is truly abrupt, loss of consciousness likely.
