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.
