Severe iron-deficiency anemia after short-term moderate consumption of green tea in woman: A rare case report.

While the mechanisms by which tea consumption hinders iron absorption are well understood, tea-related anemia usually stems from prolonged and excessive intake, which obstructs iron absorption and depletes the body's iron reserves. Consequently, it is uncommon for hemoglobin levels to plummet by 6.9 g/dl solely due to moderate tea consumption over a span of three months. We present a case of severe iron-deficiency anemia in a woman following short-term, moderate green tea consumption. After modifying her tea intake regimen, there was no recurrence of anemia. Clinicians should be mindful that even moderate tea consumption can precipitate severe iron-deficiency anemia in individuals particularly vulnerable to its effects on iron absorption.
