SCD

Definition

Sickle Cell Disease (SCD) is a genetic blood disorder characterized by the production of abnormal hemoglobin, leading to rigid, sickle-shaped red blood cells. These malformed cells can obstruct blood flow and cause various health complications.

5 Must Know Facts For Your Next Test

1. SCD primarily affects individuals of African, Mediterranean, Middle Eastern, and Indian ancestry.
2. Patients with SCD are at increased risk for severe anemia due to the rapid breakdown of sickle cells.
3. Nutritional management for SCD includes ensuring adequate intake of folic acid, omega-3 fatty acids, and antioxidants.
4. Hydration is crucial for people with SCD to help prevent vaso-occlusive crises caused by dehydrated sickle-shaped cells clumping together.
5. Vitamin D deficiency is common in SCD patients and can contribute to bone health issues; supplementation may be necessary.
