Study Notes
Iron Deficiency Anemia
Causes
- Inadequate dietary iron intake
- Increased iron demand (e.g., pregnancy, growth spurts)
- Blood loss (e.g., menstruation, gastrointestinal bleeding)
- Poor iron absorption (e.g., celiac disease, gastric bypass surgery)
- Chronic diseases (e.g., rheumatoid arthritis, cancer)
Symptoms
- Fatigue
- Weakness
- Shortness of breath
- Dizziness or lightheadedness
- Headaches
- Pale skin
- Cold hands and feet
- Poor appetite
- Restless leg syndrome
Diagnosis
- Complete Blood Count (CBC) to evaluate hemoglobin and hematocrit levels
- Peripheral blood smear to evaluate red blood cell morphology
- Iron studies:
- Serum iron levels
- Total iron-binding capacity (TIBC)
- Transferrin saturation
- Ferritin levels
- Other tests may be ordered to rule out underlying causes (e.g., endoscopy for gastrointestinal bleeding)
Treatment Options
-
Oral Iron Supplementation:
- Ferrous sulfate, fumarate, or gluconate
- Dosage: 100-200 mg of elemental iron per day
- Side effects: nausea, vomiting, constipation, diarrhea
-
Intravenous Iron:
- Indicated for severe anemia, intolerance to oral iron, or malabsorption
- Iron dextran, ferric carboxymaltose, or iron sucrose
-
Addressing Underlying Causes:
- Dietary changes to increase iron intake
- Treatment of underlying conditions (e.g., celiac disease, gastrointestinal bleeding)
-
Blood Transfusions:
- Rarely necessary, typically in severe cases or those with active bleeding
Iron Deficiency Anemia
Causes
- Low dietary iron intake can lead to iron deficiency anemia
- Increased iron demand during pregnancy, growth spurts, and other periods of rapid growth can cause iron deficiency anemia
- Blood loss due to menstruation, gastrointestinal bleeding, and other forms of bleeding can lead to iron deficiency anemia
- Poor iron absorption can occur in people with celiac disease, gastric bypass surgery, and other conditions that affect digestion
- Chronic diseases like rheumatoid arthritis and cancer can increase the risk of iron deficiency anemia
Symptoms
- Fatigue is a common symptom of iron deficiency anemia
- Weakness and shortness of breath can occur due to inadequate oxygen delivery to tissues
- Dizziness or lightheadedness can occur when the brain does not receive enough oxygen
- Headaches are a common symptom of iron deficiency anemia
- Pale skin is a visible sign of iron deficiency anemia
- Cold hands and feet can occur due to poor blood circulation
- Poor appetite can lead to nutritional deficiencies
- Restless leg syndrome can occur due to iron deficiency anemia
Diagnosis
- Complete Blood Count (CBC) measures hemoglobin and hematocrit levels to diagnose anemia
- Peripheral blood smear evaluates red blood cell morphology
- Iron studies include:
- Serum iron levels to assess iron availability
- Total iron-binding capacity (TIBC) to assess iron storage and transport
- Transferrin saturation to assess iron transport and storage
- Ferritin levels to assess iron storage
- Other tests may be ordered to rule out underlying causes of iron deficiency anemia
Treatment Options
- Oral Iron Supplementation: ferrous sulfate, fumarate, or gluconate can be used to treat iron deficiency anemia
- Dosage: 100-200 mg of elemental iron per day
- Side effects: nausea, vomiting, constipation, diarrhea
- Intravenous Iron: iron dextran, ferric carboxymaltose, or iron sucrose may be used for severe anemia, intolerance to oral iron, or malabsorption
- Addressing Underlying Causes: dietary changes to increase iron intake, treatment of underlying conditions (e.g., celiac disease, gastrointestinal bleeding)
- Blood Transfusions: rarely necessary, typically in severe cases or those with active bleeding
Iron Deficiency Anemia
Symptoms
- Fatigue and weakness, a common symptom of iron deficiency anemia
- Shortness of breath, due to decreased oxygen delivery to the body
- Pale skin, a result of reduced hemoglobin levels
- Headaches, dizziness, and lightheadedness, caused by inadequate oxygen supply to the brain
- Cold hands and feet, a symptom of poor circulation
- Hair loss, a consequence of iron deficiency
- Poor appetite, a result of reduced iron levels
- Restless leg syndrome, a common complaint among anemia patients
- Poor concentration and decreased productivity, due to inadequate oxygen supply to the brain
Diagnosis
- Complete Blood Count (CBC) measures hemoglobin and hematocrit levels to diagnose anemia
- Peripheral blood smear examines red blood cell morphology to identify abnormalities
- Iron studies, including serum iron, TIBC, and serum ferritin, help diagnose iron deficiency
- Endoscopy and colonoscopy rule out gastrointestinal bleeding as an underlying cause
Causes
- Inadequate dietary iron intake, a common cause of iron deficiency anemia
- Increased iron demand, such as during pregnancy or growth spurts
- Chronic blood loss, including menstruation and gastrointestinal bleeding
- Impaired iron absorption, often seen in patients with celiac disease or gastric bypass surgery
- Inflammatory bowel disease, such as Crohn's disease or ulcerative colitis, increases iron deficiency risk
- Chronic kidney disease, a common underlying cause of anemia
- Malignancy, including colon cancer, can contribute to iron deficiency anemia
Treatment Options
- Dietary changes: increasing iron-rich food intake, such as red meat, poultry, fish, beans, and lentils
- Iron supplements: ferrous sulfate, ferrous gluconate, and ferrous fumarate are commonly used
- Vitamin C: enhances iron absorption when taken with iron supplements
- Intravenous iron therapy: used for severe cases or those who cannot tolerate oral supplements
- Blood transfusions: necessary for severe cases with severe anemia or cardiovascular instability
- Addressing underlying causes: treating underlying conditions, such as gastrointestinal bleeding or inflammatory bowel disease, is crucial for successful treatment
