In simple words: Iron deficiency anemia means your body doesn't have enough iron to make healthy red blood cells. These cells carry oxygen throughout your body.A shortage of these cells can make you feel tired and weak.

Iron deficiency anemia is a condition characterized by a deficiency of iron in the body, leading to a reduction in the number of red blood cells and a decrease in hemoglobin levels. This results in insufficient oxygen delivery to the body's tissues and organs.

Example 1: A 25-year-old female presents with fatigue, shortness of breath, and pale skin. Blood tests reveal low hemoglobin and hematocrit, along with low serum iron and ferritin levels. She reports heavy menstrual periods. Diagnosis: D50 Iron deficiency anemia., A 60-year-old male experiences fatigue and weakness. After further investigation, including a colonoscopy, he is diagnosed with colon cancer. Blood tests also reveal iron deficiency anemia. Diagnosis: D50 Iron deficiency anemia secondary to colon cancer., A 1-year-old child is brought in for a check-up due to pallor and poor appetite. The child primarily drinks cow's milk. Blood tests indicate low hemoglobin and iron levels. Diagnosis: D50 Iron deficiency anemia due to inadequate dietary iron intake.

Documentation should include signs and symptoms, relevant medical history (e.g., heavy menstrual bleeding, gastrointestinal issues, dietary habits), laboratory results (CBC, iron studies), and any diagnostic procedures performed (e.g., endoscopy, colonoscopy).
