Quizplus · Accepted Answer

Pernicious anemia is primarily caused by a deficiency of vitamin B12, which can occur due to a variety of reasons such as poor absorption in the gastrointestinal tract, autoimmune disorders, or insufficient intake through diet. Cretinism is a congenital condition caused by an iodine deficiency, malaria is a mosquito-borne infectious disease, and diarrhea can lead to dehydration and electrolyte imbalances but is not directly linked to pernicious anemia.
