Answer: (a) Both Assertion (A) and Reason (R) are the true and Reason (R) is a correct explanation of Assertion (A).

Explanation:

The stomach is essential for iron absorption from the diet. The oxyntic cells in the stomach secrete hydrochloric acid (HCl), which aids in the conversion of ferric iron in meals to the more easily absorbable ferrous form. Iron can be easily absorbed in the upper part of the small intestine once it has been converted to ferrous form.

When a person has a gasterectomy (the removal of the stomach), their ability to make HCl is lost. As a result, iron in the diet cannot be transformed properly into the ferrous form for absorption. As the body's iron stores decline, this can lead to iron deficiency anaemia.

Iron deficiency anaemia occurs when the body does not have enough iron to generate hemoglobin, the protein found in red blood cells that transports oxygen throughout the body. Fatigue, weakness, pale complexion, shortness of breath, dizziness, and headaches are some of the symptoms of iron deficiency anaemia.

Therefore, Gasterectomy can cause iron deficiency anemia because the stomach plays a critical role in converting dietary iron to its absorbable form, and the removal of the stomach eliminates this important function.
