What is the recommended treatment for an adult male patient diagnosed with iron deficiency anemia without GI bleeding?

The recommended treatment for an adult male patient diagnosed with iron deficiency anemia without gastrointestinal bleeding is the oral administration of ferrous sulfate. This treatment is appropriate because ferrous sulfate is an effective and commonly used iron supplement that helps increase iron levels in the body, thereby addressing the deficiency that causes anemia.

In cases where there is no evidence of GI bleeding, oral iron supplements are typically the first line of treatment. Ferrous sulfate is readily available, inexpensive, and can be taken at home, which enhances patient compliance. The prescribed dosage of 300 mg three times a day (tid) provides sufficient elemental iron to promote the replenishment of iron stores and improve hemoglobin levels over time.

Other treatment options would not be appropriate in this scenario. While iron dextran is an iron supplementation option, it is usually indicated for patients who either cannot tolerate oral iron or have specific reasons that necessitate parenteral iron administration, which is not the case here. Stool guaiac testing is used to detect hidden blood in the stool and would be more relevant if GI bleeding were suspected. Referring to a hematologist would typically occur if the anemia was more complicated or if it did not respond to initial treatments, but in this case, initial management with oral iron is sufficient
