Pernicious Anemia Definition and Symptoms

Pernicious anemia is a decrease in red blood cells which happens because the intestines cannot absorb vitamin B12 correctly.

Symptoms include confusion, fatigue, problems concentrating, swollen tongue, shortness of breath, constipation or diarrhea, loss of appetite, and the desire to eat non food items.
