Final answer:
Serum ferritin levels rise due to iron overload, which can affect iron absorption and lead to iron accumulation in the body.
Step-by-step explanation:
Serum ferritin increases with iron overload, which interferes with iron absorption. This condition may arise from an excess of iron in the body and can lead to deposits of iron in various tissues like the liver. Serum ferritin serves as a marker for the iron stores in the body and is instrumental in diagnosing iron-related disorders. Iron is vital for various physiological functions, such as oxygen transport to tissues, and is an integral component of hemoglobin which carries oxygen in the blood. When excessive iron accumulates, it can also be deposited as hemosiderin, indicating disturbances in iron metabolism. These abnormalities can stem from decreased formation of hemoglobin or abnormalities in the serum iron concentration, among others.
Serum ferritin is a protein that stores iron in the body. When there is an excess of iron in the body, such as in cases of iron overload, the concentration of serum ferritin increases. Iron overload can occur due to conditions like primary disorders of iron metabolism or secondary factors that result in excessive iron entry into the body. This increase in serum ferritin interferes with iron absorption, which can lead to further iron overload.
The correct answer is c) Iron overload; iron absorption.
