Causes of B12 Malabsorption

Vitamin B12 malabsorption comes from many causes. These include conditions that stop it from being absorbed. Knowing these causes helps in finding and fixing health problems.

Intrinsic Factor Deficiency

Pernicious Anemia

Pernicious anemia is when the body attacks the intrinsic factor makers. This stops B12 absorption. It leads to fewer healthy red blood cells and severe anemia if not treated.

Gastrointestinal Disorders
