Which of the following is NOT a known cause of folic acid deficiency anemia?

Folic acid deficiency anemia occurs when there is insufficient folate in the body, which is crucial for the production of red blood cells. Various factors can contribute to this deficiency.

Chemotherapy is known to affect rapidly dividing cells, including those in the bone marrow that produce blood cells. Many chemotherapeutic agents can interfere with folate metabolism, leading to anemia.

Alcoholism is a significant contributor to folic acid deficiency. Chronic alcohol consumption can impair the absorption of folate and lead to poor dietary intake, both of which can result in anemia.

A poor diet, particularly one lacking in fruits and vegetables, can lead to insufficient intake of folate, contributing to folic acid deficiency anemia.

Acetazolamide, however, is primarily a carbonic anhydrase inhibitor used to treat conditions like glaucoma, edema, and altitude sickness. While it is not commonly associated with causing folic acid deficiency, it may have other side effects related to electrolyte balance and does not directly prevent the absorption or metabolism of folic acid. Therefore, it is not regarded as a known cause of folic acid deficiency anemia.
