Classification of anemia for gastroenterologists

Area of Science:

• Gastroenterology
• Hematology

Background:

• Anemia is frequently linked to the digestive system through dietary deficiencies, malabsorption, or chronic bleeding.
• Understanding anemia's classification and diagnostic pathways is crucial for effective patient management.

Purpose of the Study:

• To provide a comprehensive review of anemia classification and diagnostic interpretation.
• To propose a hierarchical and logical diagnostic approach for gastroenterologists, focusing on digestive system causes.
• To emphasize diagnostic efficiency and resource optimization.

Main Methods:

• Review of the World Health Organization definition and morphological/pathogenic classifications of anemia.
• Detailed interpretation of laboratory tests, from basic to specialized hematological and biochemical assays.
• Development of diagnostic algorithms integrating clinical, laboratory, and procedural findings.

Main Results:

• An integrated classification system for anemia is presented.
• A structured diagnostic strategy is proposed, prioritizing common gastrointestinal causes.
• Emphasis on efficient management of medical interviews, physical examinations, and laboratory testing.

Conclusions:

• A systematic approach facilitates rapid and accurate diagnosis of anemia, particularly in the context of digestive diseases.
• The proposed methodology aids gastroenterologists in diagnosing the most prevalent causes of anemia efficiently.
• Practical rules are provided to guide diagnosis and care, optimizing resource utilization.
