“A Comprehensive Review of Anaemia Associated with Hypothyroidism”

Abstract

Background: Thyroid hormones play a crucial role in erythropoiesis, both directly and indirectly, with reduced secretion potentially causing anaemia—a commonly overlooked symptom of hypothyroidism. By compiling existing data, discussing recent advancements, identifying root causes, and proposing potential treatment options, this work acknowledges the complexity of the issue and aims to serve as a foundational reference for those in the early stages of research or clinical practice. Methods: To comprehend the concept of this disease condition, a number of medical textbooks were consulted. Various search engines, such as PubMed, Google Scholar, Research Gate, Science Direct, Scopus, etc., were cited to explore the recent advancements and obtain data on the topic in question. Later, all the information and data gathered were organised into a review article. Conclusion: Anemia, often referred to as the “haematological mask” of hypothyroidism, can manifest even before hypothyroidism is clinically diagnosed. Hypothyroidism must be considered as a potential cause when confronted with refractory anemia, as its treatment is pivotal for achieving comprehensive and lasting improvements in haematological parameters.
