About Sickle cell anemia:

• It is an inherited blood disorder.
• It affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. 
• People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
• These sickle cells also become rigid and sticky, which can slow or block blood flow.

What causes it?

• • The cause of Sickle cell disease is a defective gene, called a sickle cell gene.
  • A person will be born with sickle cell disease only if two genes are inherited—one from the mother and one from the father.

Symptoms:

• • Early stage: Extreme tiredness or fussiness from anemia, painfully swollen hands and feet, and jaundice.
  • Later stage: Severe pain, anemia, organ damage, and infections.

Treatments:

• • The only cure for this disease is bone marrow or stem cell transplantation.
  • However, there are treatments that can help relieve symptoms, lessen complications, and prolong life.
