Definition

Hemoglobinopathy is a group of genetic disorders characterized by abnormal structure or production of hemoglobin, the protein in red blood cells that carries oxygen. These disorders can lead to various health complications, including anemia and organ damage.

5 Must Know Facts For Your Next Test

1. Hemoglobinopathies are often inherited and include well-known conditions such as sickle cell disease and thalassemia.
2. Nutritional management for individuals with hemoglobinopathies often focuses on preventing iron overload and ensuring adequate intake of folate and vitamin B12.
3. Patients with hemoglobinopathies may require regular blood transfusions, which can impact their nutritional needs and increase the risk of iron overload.
4. Dietary recommendations may include avoiding iron-rich foods or taking chelation therapy to manage excess iron levels.
5. Antioxidant-rich foods can be beneficial for patients with hemoglobinopathies due to their increased oxidative stress.
