Study Notes
Blood Loss and Destruction
- Decrease in red blood cell (RBC) production can occur due to deficiencies in precursor substances or impaired bone marrow function.
Iron Deficiency Anemia (IDA)
- Common causes include malabsorption of iron, high gastric hydrochloric acid, gastric surgery, and vitamin C deficiency.
- Increased iron requirements during pregnancy, infancy, lactation, and menstruation can lead to IDA.
- Blood loss may result from ulcers or prolonged menstruation.
Alpha Thalassemia
- Alpha thalassemia trait: Caused by two mutated genes of alpha globin chain; typically presents with mild symptoms.
- Hemoglobin H disease: Results from three mutated genes of alpha globin chain; manifests with moderate to severe symptoms.
Chronic Blood Loss
- Chronic blood loss is the primary cause of IDA in adults, leading to microcytic hypochromic anemia.
Symptoms of Anemia
- Fatigue characterized by a lack of energy or easily tiring.
- Difficulty walking due to weakness.
- Numbness or tingling sensations in hands and feet.
Megaloblastic Anemia
- Complications of untreated or chronic megaloblastic anemia can result in permanent neurological damage due to neurodegeneration.
- Potential neurological issues include gait ataxia, which affects balance and coordination.
