What are people most likely to develop sickle cell anemia?
Who is most likely to develop sickle cell anemia? Sickle cell disease is more common in certain ethnic groups, including: People of African descent, including African-Americans (among whom 1 in 12 carries a sickle cell gene) Hispanic-Americans from Central and South America. People of Middle Eastern, Asian, Indian, and Mediterranean descent.
What part of the body does sickle cell anemia affect?
The abdominal and chest pain experienced by someone with sickle cell anemia is caused by arteries that have become obstructed by a buildup of sickle cells. If sickle cells cause spleen damage, the body may become more prone to infection. Sickle cell anemia can also damage blood vessels in the eyes, decreasing vision.
How is sickle cell anemia influenced by environmental factors?
… The clinical and phenotypic heterogeneity of patients with sickle cell anemia (SCA) is influenced by environmental and genetic factors. Several genetic modifiers, such as the KLOTHO ( KL) gene, have been associated with SCA clinical outcomes.
What happens in sickle cell anemia, exactly?

What is the main cause of sickle cell anemia?
What causes sickle cell disease? Sickle cell is an inherited disease caused by a defect in a 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. A person who inherits just one gene is healthy and said to be a "carrier" of the disease.
What is sickle cell anemia and who does it affect?
Sickle cell anemia is a form of the inherited blood disorder, sickle cell disease. Sickle cell anemia affects your red blood cells, turning them from round flexible discs into stiff and sticky sickled cells. Sickled cells keep red blood cells from doing their job, which is carrying oxygen throughout your body.
How does sickle cell anemia affect daily life?
Some examples include: hearing loss, vision problems, acute chest syndrome, jaundice, priapism (persistent and painful erections), leg ulcers, gallstones, and stroke. Sickle cell anemia also can have a negative impact on the mental health of patients and may lead to depression and anxiety.
What are the 3 main causes of anemia?
Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body. Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.
How does anemia affect the body?
If you have anemia, your body does not get enough oxygen-rich blood. The lack of oxygen can make you feel tired or weak. You may also have shortness of breath, dizziness, headaches, or an irregular heartbeat.

How does sickle cell affect students?
Students with sickle cell disease may miss class time or be absent for doctor visits or hospital stays. Give these students special consideration regarding missed instruction, assignments, and testing. Chronic fatigue or pain can make it appear that students aren't motivated to learn.
What is the most common complication of sickle cell disease?
Pain. Pain is the most common complication of SCD, and the top reason that people with SCD go to the emergency department or hospital. Sickled cells traveling through small blood vessels can get stuck and block blood flow throughout the body, causing pain.
What is sickle cell anemia simple definition?
In sickle cell anemia, some red blood cells look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of inherited disorders known as sickle cell disease. It affects the shape of red blood cells, which carry oxygen to all parts of the body.

What is the first sign of sickle cell anemia?
Fever. People with sickle cell anemia have an increased risk of serious infection, and fever can be the first sign of an infection.
What does sickle cell anemia look like?
Overview. Normal red blood cells are rounded and disk-shaped. In sickle cell anemia, some red blood cells become deformed, so they look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of disorders known as sickle cell disease.
What happens if you have sickle cells in your eyes?
Tiny blood vessels that supply your eyes can become plugged with sickle cells. This can damage the retina — the portion of the eye that processes visual images — and lead to vision problems.
How long do sickle cells last?
Red blood cells usually live for about 120 days before they need to be replaced. But sickle cells usually die in 10 to 20 days, leaving a shortage of red blood cells (anemia).
What is the name of the substance that is produced by the breakdown of red blood cells?
Gallstones. The breakdown of red blood cells produces a substance called bilirubin. A high level of bilirubin in your body can lead to gallstones.
Can anemia cause a stroke?
Sickle cell anemia can lead to a host of complications, including: Stroke. Sickle cells can block blood flow to an area of your brain. Signs of stroke include seizures, weakness or numbness of your arms and legs, sudden speech difficulties, and loss of consciousness.
What is sickle cell anemia?
Sickle cell anemia causes the body’s red blood cells to form a thin, sickle shape, making it hard for them to move easily through the blood vessels. These sickle-shaped red blood cells are fragile and deteriorate quickly, lasting only around 10-20 days—a short lifespan when compared to a typical red blood cell, which lasts around 120 days.
Which group has the highest risk of sickle cell anemia?
African Americans are at the highest risk for contracting sickle cell anemia with 1 in every 500 African American children developing the disease.
How long do sickle cells last?
These sickle-shaped red blood cells are fragile and deteriorate quickly, lasting only around 10-20 days —a short lifespan when compared to a typical red blood cell, which lasts around 120 days.
What is the condition that affects the way blood cells carry oxygen through the body?
Anemia, a common blood disorder that affects the way blood cells carry oxygen through the body, affects over 3 million Americans. In anemic individuals, red blood cells are unable to adequately nourish the tissues and organs with oxygen, which can result in symptoms like dizziness, fatigue, and accelerated heartbeat.
What happens when blood flow is blocked to the hands and feet?
Swelling of hands and feet. When blood flow is blocked to the hands and feet, swelling may occur.
Is sickle cell anemia dangerous?
Sickle cell anemia has intense, uncomfortable, and dangerous effects on the body. Although typically diagnosed in infancy, if someone develops fever, episodes of severe pain, swelling of the hands, feet or abdomen, yellow tint to the skin, or any signs/symptoms of stroke, they should consult a medical professional immediately as it could be signs of anemia.
Can sickle cell anemia cause shortness of breath?
Since the disease limits blood flow to various parts of the body, it can cause shortness of breath, more frequent infections, general discomfort, or extreme pain. It can also affect lung performance, putting those with sickle cell anemia at extreme risk for complications from COVID-19.
When do sickle cell anemia symptoms appear?
Symptoms of sickle cell anemia usually show up at a young age. They may appear in babies as early as 4 months old, but generally occur around the 6-month mark. While there are multiple types of SCD, they all have similar symptoms, which vary in severity. These include:
What is sickle cell disease?
Sickle cell anemia, or sickle cell disease (SCD), is a genetic disease of the red blood cells (RBCs). Normally, RBCs are shaped like discs, which gives them the flexibility to travel through even the smallest blood vessels. However, with this disease, the RBCs have an abnormal crescent shape resembling a sickle.
How long do sickle cells live?
This breaking apart of RBCs is called chronic hemolysis. RBCs generally live for about 120 days. Sickle cells live for a maximum of 10 to 20 days.
What is the most common type of sickle cell disease?
Hemoglobin SS disease is the most common type of sickle cell disease. It occurs when you inherit copies of the hemoglobin S gene from both parents. This forms hemoglobin known as Hb SS. As the most severe form of SCD, individuals with this form also experience the worst symptoms at a higher rate.
Why do sickle cells deform?
The red blood cells are more likely to deform and assume the sickle shape if you’re dehydration . Treating underlying or associated infections is an important part of managing the crisis, as the stress of an infection can result in a sickle cell crisis. An infection may also result as a complication of a crisis.
How to help sickle cell pain?
There are things you can do at home to help your sickle cell symptoms: Use heating pads for pain relief. Take folic acid supplements, as recommended by your doctor. Eat an adequate amount of fruits, vegetables, and whole-wheat grains.
Is beta zero thalassemia the same as Hb SS?
Sickle beta-zero thalassemia is the fourth type of sickle cell disease. It also involves the beta globin gene. It has similar symptoms to Hb SS anemia. However, sometimes the symptoms of beta zero thalassemia are more severe. It is associated with a poorer prognosis.
What are the symptoms of sickle cell anemia?
What are the symptoms and complications of sickle cell anemia? 1 Periods of pain that can last a few hours to a few days. 2 Blood clots. 3 Swelling in hands and feet. 4 Joint pain that resembles arthritis. 5 Chronic neuropathic pain (nerve pain). 6 Life-threatening infections. 7 Anemia (decrease in red blood cells).
What happens to red blood cells when they become sickle shaped?
The sickle-shaped red blood cells: Clog blood vessels, causing episodes of pain and cutting off oxygen to tissues and organs. Get trapped in the spleen (an organ that gets rid of old cells) where they are destroyed.
What is the name of the disease that causes red blood cells to change shape?
Sickle cell anemia is a blood disease that affects red blood cells. Normal red blood cells are round. In people with sickle cell anemia, hemoglobin – a substance in red blood cells – becomes defective and causes the red blood cells to change shape. The faulty hemoglobin is called hemoglobin S (HgbS), and it replaces normal hemoglobin which is called hemoglobin A (HgbA). Over time, the red blood cells become rigid and shaped like crescent moons or sickles.
Why do we need to test for sickle cell disease?
The testing is done right away so that children born with sickle cell disease can receive treatment to protect them against life-threatening infections.
How many chances do sickle cell patients have children?
If two people with sickle cell trait have children together, there is a 1 in 4 chance that their children will have sickle cell anemia.
What is the chance of a child being born with sickle cell anemia?
If you and your partner both have sickle cell trait, your child has a 25% chance of being born with sickle cell anemia. If only one of you has sickle cell trait, your child cannot be born with sickle cell anemia, but there is a 50% chance that your child will be born with sickle cell trait.
Can sickle cell anemia be passed on to children?
People with sickle cell anemia inherit the disease, which means that the disease is passed on to them by their parents as part of their genetic makeup. Parents cannot give sickle cell anemia to their children unless they both have the faulty hemoglobin in their red blood cells.
In the United States
The exact number of people living with SCD in the U.S. is unknown. Working with partners, the CDC supports projects to learn about the number of people living with SCD to better understand how the disease impacts their health.
