Why hemoglobin levels may decrease with age

Bone marrow slowdown: Aging bone marrow produces fewer red blood cells.

Vitamin deficiencies: Lack of vitamin B12, folate, or vitamin C.

Iron deficiency: Inadequate dietary iron or poor absorption.

Medications: Certain drugs, such as proton pump inhibitors, can interfere with nutrient absorption.

Chronic inflammation: Ongoing inflammation can lead to anemia.

Chronic diseases: Conditions like anemia, kidney disease, or cancer.

Hormonal changes: Decreased erythropoietin production in the kidneys.

Malabsorption: Impaired nutrient absorption due to gut changes.

Increased oxidative stress: Damage to red blood cells.

 Genetic factors: Inherited traits affecting hemoglobin production.
