    Sickle cell disease is a blood disorder in which the hemoglobin is damaged and can't carry oxygen to the tissues. These blood cells with the defective hemoglobin are sticky and can build up and block small blood vessels leading to pain and other complications of the disease.

    Defining Sickle Cell Disease and Its Economic Burden. Sickle cell disease (SCD) is the consequence of homozygosity for a single amino acid change in the β-globin chain that results in structurally abnormal hemoglobin S, or by compound heterozygosity for hemoglobin S and another β-globin chain abnormality, typically hemoglobin C or β-thalassemia.

    Sickle cell anemia is an inherited disease that affects red blood cells with an abnormal version of hemoglobin, the protein that carries oxygen throughout the body. The altered hemoglobin is known as hemoglobin S, or sickle hemoglobin, because it causes normally oval-shaped red blood cells to...

    Mar 25, 2020 · Sickle cell disease is an inherited disorder causing normal red blood cells to deform into stiff, crescent shapes that get stuck in small blood vessels blocking blood flow and oxygen delivery to many parts of the body. This ‘sickling’ is triggered by events such as viral illnesses, cold weather, stress, and low oxygen, among others.

Sickle Cell Crisis (Inpatient Care) - What You Need to Know

    https://www.drugs.com/cg/sickle-cell-crisis-inpatient-care.html
    Feb 03, 2020 · A sickle cell crisis is a painful episode that occurs in people who have sickle cell anemia. It happens when sickle-shaped red blood cells (RBCs) block blood vessels. Blood and oxygen cannot get to tissues, causing pain. A sickle cell crisis can also damage your tissues and cause organ failure, such liver or kidney failure.
