Defective red blood cells due to stomach enzyme deficiency?

There is no direct link between stomach enzyme deficiency and the production of defective red blood cells. Red blood cell production primarily occurs in the bone marrow under normal circumstances and is regulated by various growth factors and nutrients such as iron, vitamin B12, and folate. Stomach enzyme deficiencies usually manifest as digestive issues affecting the breakdown and absorption of certain nutrients in the stomach and small intestine. They typically do not have a direct impact on red blood cell production unless they lead to nutrient deficiencies or systemic conditions that indirectly affect bone marrow function or nutrient utilization.
