Causes, symptoms, diagnostic procedures and criteria, treatments and prognoses for sickle cell disease, a genetic disorder that results in sickle-shaped red blood cells.

Sickle Cell Disease, Topic Overview - WebMD

Sickle cell disease changes normal, round red blood cells into cells that can be shaped like crescent moons. The name "sickle cell" comes from the crescent shape of the cells. (A sickle is a tool with a crescent-shaped blade.)

Sickle cell disease is the most common inherited blood disorder in the United States. Approximately 100,000 Americans have the disease.

What Is Sickle Cell Disease? - NIH

The term sickle cell disease (SCD) describes a group of inherited red blood cell disorders. People with SCD have abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in their red blood cells.

Facts About Sickle Cell Disease - CDC

SCD is a group of inherited red blood cell disorders. Healthy red blood cells are round, and they move through small blood vessels to carry oxygen to all parts of the body. In someone who has SCD, the red blood cells become hard and sticky and look like a C-shaped farm tool called a âsickleâ.

Sickle Cell Disease Information - Center for Sickle Cell Disease

Sickle cell disease, often called sickle cell anemia or just "sickle cell", is an inherited condition that affects hemoglobin within the red blood cells. The presence of sickle hemoglobin (HbS) leads to the formation of crescent or sickle-shaped cells that are rigid and sticky and which tend to occlude (clog or close up) small blood vessels. Depending on the organ involved, this occlusion leads to episodes of pain, death of tissue and serious complications.

Sickle Cell Disease - Genetics Home Reference

Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

Sickle Cell Disease - Kid's Health

Thanks to advancements in early diagnosis and treatment, most kids born with sickle cell disease grow up to live relatively healthy and productive lives.

Sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell disease have red blood cells that contain mostly hemoglobin* S, an abnormal type of hemoglobin. Sometimes these red blood cells become sickle-shaped (crescent shaped) and have difficulty passing through small blood vessels. Learn more here.

Sickle Cell Anemia: Learn About SCD Symptoms and Treatment - Medicine Net

Read about sickle cell anemia (sickle cell disease), a blood disease which shortens life expectancy, is caused by an inherited abnormal hemoglobin. Symptoms may include bacterial infections, painful swelling of the hands and feet, fever, arthritis, leg ulcers, fatigue, anemia, eye damage, and lung and heart injury. Treatment for sickle cell anemia aims to manage and prevent the worst manifestations of the disease and focuses on therapies that block red blood cells from stacking together, which can lead to tissue and organ damage.

Sickle cell disease
Other names	Sickle cell disorder; drepanocytosis (dated)

Figure (A) shows normal red blood cells flowing freely through a blood vessel. The inset shows a cross-section of a normal red blood cell with normal haemoglobin. Figure (B) shows abnormal, sickled red blood cells sticking at the branching point in a blood vessel. The inset image shows a cross-section of a sickle cell with long polymerized sickle haemoglobin (HbS) strands stretching and distorting the cell shape to look like a crescent moon.
