Sickle cell affects millions of people around the world, but whether it should be classified as a disease or disorder remains a subject of debate. A disease is commonly defined as any deviation from normal health, while a disorder refers to a disruption of normal physical or mental functions. In the case of sickle cell, it is characterized by an abnormal shape of red blood cells, which impedes normal blood flow.
While sickle cell often presents itself in the form of a chronic condition, some experts argue that it is not a disease but instead a genetic variation. Sickle cell is more common among certain populations, and individuals who carry the sickle cell trait are thought to have an evolutionary advantage in regions that are impacted by malaria. However, for those who are symptomatic, sickle cell can be a debilitating condition that causes symptoms ranging from fatigue and pain to an increased risk of infections.
Ultimately, the decision to classify sickle cell as a disease or disorder may not have significant implications for the treatment and management of the condition. Most medical professionals agree that it requires careful monitoring and treatment, but the classification may inform research into new treatments and potential cures. As our understanding of sickle cell continues to evolve, the debate over its classification is likely to continue.
Causes and Risk Factors of Sickle Cell
Sickle cell is a group of inherited red blood cell disorders that affect hemoglobin, the molecule responsible for carrying oxygen in the blood. The disease is caused by a genetic mutation that affects the structure of hemoglobin, causing it to form abnormal, sickle-shaped red blood cells that can clog the blood vessels and cause organ damage. There are several risk factors that may increase the likelihood of developing sickle cell disease.
- Genetics: Sickle cell disease is caused by inheriting two copies of the sickle cell gene, one from each parent. If an individual inherits only one copy of the gene, they may still carry the sickle cell trait, which means they do not have the disease but can pass the gene on to their children.
- Ethnicity: Sickle cell disease primarily affects people of African descent, but it can also occur in individuals of Hispanic, Middle Eastern, or Mediterranean ancestry.
- Family history: Having a family member with sickle cell disease or trait increases the likelihood of an individual developing the disease or carrying the trait.
- Environmental factors: Certain environmental factors, such as extreme temperatures, dehydration, and high altitudes, can trigger sickle cell crises and increase the risk of complications.
It’s important to note that sickle cell disease is not contagious and cannot be contracted from another person. It’s strictly a genetic disorder that is passed down from parents to their children.
While sickle cell disease is a lifelong condition that requires management, individuals with the disease can still lead fulfilling lives with proper care and treatment.
Symptoms of Sickle Cell Disease
Sickle cell disease (SCD) is a group of inherited blood disorders that affect hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. The most common type of SCD is sickle cell anemia, which occurs when hemoglobin forms into long, rigid rods that can cause blockages and damage to blood vessels.
While symptoms of sickle cell disease can vary from person to person, the most common symptoms include:
- Pain Episodes: Pain is the most common symptom of sickle cell disease. These painful episodes, also known as a sickle cell crisis, can last from a few hours to a few weeks and can occur in different parts of the body, including the chest, back, arms, and legs.
- Anemia: Due to the destruction of red blood cells and reduced hemoglobin in sickle cell disease, patients may experience fatigue, weakness, and shortness of breath, all of which are symptoms of anemia.
Sickle cell disease can weaken the immune system, making patients more susceptible to infections such as pneumonia, meningitis, and urinary tract infections. Complications of Sickle Cell Disease
In addition to these symptoms, people with sickle cell disease may experience a range of complications, including:
- Stroke: The blockage of blood vessels in the brain can cause a stroke, a serious and potentially life-threatening condition.
- Acute Chest Syndrome: This condition occurs when sickle cells block blood vessels in the lungs, causing chest pain, fever, and difficulty breathing. This can also be a life-threatening complication.
- Organ Damage: Sickle cell disease can cause damage to various organs, including the spleen, liver, kidneys, and bones. This can lead to a range of complications such as jaundice, aseptic necrosis of bones, and kidney failure among others.
Preventing Sickle Cell Complications
Due to the high risk of complications associated with sickle cell disease, it is essential that patients have regular appointments with healthcare providers to monitor their condition. Treatment options, including medication and blood transfusions, are available to manage symptoms and complications of sickle cell disease. Additionally, staying hydrated, avoiding strenuous activity, and avoiding extreme temperatures may also help prevent complications from occurring.
Complication Treatment Pain Episodes Medications, including pain relievers and anti-inflammatory drugs, are used to treat pain episodes. Anemia Blood transfusions can help replace damaged red blood cells and improve anemia symptoms. Acute Chest Syndrome A hospital stay, oxygen therapy, and antibiotics may be required to treat this serious condition. Stroke Stroke is a medical emergency that requires immediate attention. Treatment may include medication to prevent further damage to the brain, blood transfusions, or surgery to repair blood vessels. Organ Damage Treatment for organ damage depends on the specific complication and may include surgical intervention or medication. While there is no cure for sickle cell disease, early diagnosis, proper management of symptoms, and early intervention for complications can help improve the quality of life for people living with this condition.
Diagnosis of Sickle Cell Disorder
Diagnosing sickle cell disorder requires a combination of physical exams, medical history, and laboratory tests. However, it is essential to note that sickle cell disorder is not always easy to diagnose, especially during infancy when some symptoms may not be noticeable. Here are some of the ways in which sickle cell disorder can be diagnosed:
- Newborn Screening: Most babies born in the U.S undergo a screening test for sickle cell disorder before they leave the hospital. This test analyses a sample of the baby’s blood to check for the presence of sickle hemoglobin. If the test is positive, further diagnostic tests are carried out.
- Hemoglobin Electrophoresis: This test is used to identify the different types of hemoglobin in the blood. During the test, a small sample of blood is taken from the patient, and an electric current is passed through it. This separates the different types of hemoglobin present, making it easier to identify sickle hemoglobin.
- Family History: If someone in the patient’s family has sickle cell disorder, there is a high chance that the patient may also have the disorder. Therefore, having a family history of sickle cell disorder can assist in the diagnosis of the disease.
Complications During Diagnosis
While diagnosing sickle cell disorder, physicians may encounter various complications such as:
- Misdiagnosis: There are high chances of misdiagnosis since the symptoms of sickle cell disorder are common in many other diseases. Therefore, it is crucial to perform the necessary tests to ensure an accurate diagnosis.
- Silent Carriers: Some individuals may only have one copy of the sickle cell gene, making them silent carriers of the disorder. However, they may not experience any symptoms, making it challenging to diagnose them without genetic testing.
- Non-Expression of Symptoms: In some cases, patients with sickle cell trait may develop symptoms related to sickle cell disorder under certain conditions such as high altitudes, extreme dehydration, or high-intensity workouts. Therefore, physicians may need to put the patient under these conditions to observe whether they have symptoms of sickle cell disorder.
Laboratory Tests for Diagnosis
Here are some of the laboratory tests that are used to diagnose sickle cell disorder:
Test Name Purpose Hemoglobin Electrophoresis To identify the different types of hemoglobin present in the blood and determine the percentage of sickle hemoglobin. Complete Blood Count (CBC) To count the number of red blood cells, white blood cells, and platelets. Reticulocyte Count To measure the number of immature red blood cells that the bone marrow produces and releases into the bloodstream. Diagnosing sickle cell disorder is a crucial step in understanding the disorder’s severity and implementing the appropriate treatment. Early diagnosis can significantly benefit the patient by ensuring that they receive the correct treatment plan to manage the disorder.
Treatment options for sickle cell
Sickle cell is a genetic disorder that affects red blood cells, causing them to become hard and sticky and form a crescent shape, which can obstruct blood flow and lead to severe pain and many other complications.While there is no cure for sickle cell disease, there are several treatment options available to help manage the symptoms and improve the quality of life for those with the condition. Here are some of the treatment options for sickle cell:
- Pain management: Pain is a common symptom of sickle cell disease, and it could be severe, chronic, and debilitating. Therefore, pain management is one of the critical aspects of treating sickle cell disease. Doctors typically recommend analgesics and anti-inflammatory drugs to alleviate the pain and reduce inflammation caused by sickle cell disease.
- Hydroxyurea: This medication is a disease-modifying treatment that works by stimulating the production of fetal hemoglobin in the red blood cells. Fetal hemoglobin is a type of hemoglobin that is produced in the fetus and newborns, but its production stops after a few months of birth. It is also resistant to sickling. Therefore, increasing its production in patients with sickle cell disease can improve their symptoms and reduce the frequency and severity of crises. Hydroxyurea is also useful for preventing organ damage caused by the disease.
- Blood transfusion: Blood transfusion is a treatment option where a patient receives healthy blood from a donor to replace their sickled blood. Blood transfusions can help increase the oxygen-carrying capacity of the blood and improve the symptoms of sickle cell disease. It is also beneficial for preventing or treating complications such as anemia, acute chest syndrome, strokes, and other organ damage.
Patients with sickle cell disease are also advised to adopt a healthy lifestyle and avoid triggers that can cause crises. They are encouraged to eat a healthy diet rich in fruits, vegetables, whole grains, and lean protein sources, stay hydrated, get regular exercise, and avoid excessive consumption of alcohol and smoking. Furthermore, patients should receive regular medical checkups and follow their doctor’s advice and treatment plan to manage their condition effectively.
It is essential to note that treatment options for sickle cell disease vary from person to person, depending on their symptoms, medical history, age, and overall health status. Therefore, it is crucial to consult a doctor or a sickle cell specialist to determine the best treatment plan and options for each patient.
Treatment Options Benefits Risks Pain management Alleviates pain and reduces inflammation May cause adverse side effects such as nausea, dizziness, and constipation Hydroxyurea Stimulates fetal hemoglobin production, reduces the frequency, and severity of crises, prevents organ damage May cause side effects such as anemia, hair loss, and increased risk of infections and other cancers Blood transfusion Increases oxygen-carrying capacity, improves symptoms, prevents/treats complications such as anemia and organ damage May cause allergic reactions, infections, iron overload, and other complications In summary, treatment options for sickle cell disease are essential to manage the symptoms, prevent complications and improve the quality of life for patients. Pain management, Hydroxyurea, and blood transfusion are among the most commonly used treatment options for sickle cell disease, and they come with benefits and risks that patients and doctors need to weigh. Patients should work closely with their doctors to determine the best treatment plan and options for their condition.

As more is learned about the underlying mechanisms of sickle cell disease, and new technologies become available to facilitate research, the outlook for those with sickle cell disease grows increasingly optimistic.
Advocacy and Awareness for Sickle Cell Disease and Disorders
Sickle cell disease (SCD) is a genetic blood disorder that affects millions of people worldwide, mostly of African descent. Due to the lack of awareness and advocacy, many individuals affected by SCD are often misunderstood and overlooked, leading to delayed diagnosis and inadequate treatment.
Here are some advocacy and awareness efforts that can help improve the lives of individuals with SCD:
- Education: Raising awareness about SCD is crucial, starting from schools, primary care facilities, and communities. This can be achieved by incorporating comprehensive SCD education in healthcare curriculums and organizing community forums that offer education and information about SCD.
- Advocacy: Advocating for SCD research and funding is essential in promoting better understanding, treatments, and eventually finding a cure for the disease. It would require increasing government funding and collaboration among patient advocacy groups, healthcare providers, and research institutions.
- Access to Care: People with SCD often struggle to access the care they need to manage their condition. Advocacy efforts should aim to improve access to healthcare for people with SCD while reducing the disparities in care. This can be achieved by increasing the number of trained providers, improving health insurance coverage, and increasing the awareness of the disease in the medical community.
Sickle Cell Disease Vs. Disorder
Sickle Cell Disease (SCD) is often interchangeably used with Sickle Cell Disorder (SCD). However, there is a subtle difference between the two. SCD encompasses all conditions where an individual inherits sickle hemoglobin from one or both parents. The term SCD includes all symptom variations, ranging from asymptomatic cases to severe ones that may cause more health complications.
SCD is not a single disorder but a group of inherited blood disorders. The most common form is Hemoglobin SS disease. There are also other sickle cell forms, such as SC disease, Sβ-thalassemia, and sickle cell trait (SCT). Sickling of the red blood cells makes them more prone to causing blockages in blood vessels, leading to multiple complications.
Sickle Cell Disease and Disorders Complications Table
Complications Description Anemia The body lacks enough healthy red blood cells to carry oxygen throughout the body Avascular Necrosis This is a painful condition that occurs when there is a loss of blood supply to the bone, leading to bone death. Pain Crisis It’s a hallmark of SCD. Painful episodes can last from a few hours to several weeks and can happen more frequently in some individuals. Stroke SCD patients are at higher risk of developing a stroke due to blocked blood vessels in the brain and decreased oxygen supply. Acute Chest Syndrome A life-threatening condition that occurs when sickle cells block the blood vessels in the lung There are numerous other complications caused by SCD, such as organ damage, infections, and complications in pregnancy.
