Vitamin B12 Deficiency Anemia

Vitamin B12 deficiency anemia occurs when the body lacks this vitamin, which is needed to produce healthy red blood cells and maintain the nervous system. As a consequence, the blood carries less oxygen to the tissues.

Common symptoms: persistent tiredness, paleness, shortness of breath on exertion and, in some cases, tingling in the hands and feet or difficulty concentrating.

Common causes: they are usually related to poor intestinal absorption, certain digestive conditions, or a diet low in animal-source foods.

Which specialist treats it? The hematologist studies alterations of the blood, while the gastroenterologist or the general surgeon are involved when the origin is digestive. If you notice unexplained fatigue or these signs, it is advisable to discuss it with a professional who can evaluate your case and guide the pertinent studies.
