The first aspect of treating patients with iron deficiency anemia is etiological treatment. It is necessary to remove the causes of iron deficiency as much as possible. While simple iron supplementation can restore blood indices, if the primary disease is not actively treated, it cannot fundamentally solve anemia. If left untreated, anemia in patients is prone to recurrence. Secondly, iron supplementation is the clinical priority, with oral iron supplements being the most commonly used treatment. Ferrous preparations such as ferrous succinate and ferrous fumarate are most often used. These medications are generally taken with meals or after meals to reduce gastrointestinal irritation. This raises the issue of whether patients with iron deficiency anemia can drink tea. When iron supplements are taken with tea, they can bind with the tannins in the tea to form an insoluble precipitate that is difficult to absorb. Thus, it is clinically advised that patients with iron deficiency anemia should avoid drinking tea, as it can reduce the absorption of iron and thus result in suboptimal treatment outcomes.
