What is Sickle Cell Disease?
Sickle cell disease is a genetic condition that affects how red blood cells carry oxygen through the body. Instead of being soft and round, the cells become stiff and shaped like a crescent. These abnormal cells can block blood flow and reduce oxygen delivery, leading to pain and possible organ damage.
More serious complications may include lung problems, stroke, or damage to organs like the spleen, kidneys, or eyes.
Symptoms
Sickle cell disease is present at birth and develops due to inherited genes. Symptoms can range from mild to severe and may change over time.
Common symptoms include:
- Ongoing tiredness or weakness from anemia
- Episodes of intense pain, often in the chest, arms, or legs
- Yellowing of the skin or eyes (jaundice)
- Frequent infections
- Swelling in hands and feet
- Shortness of breath
How is it diagnosed?
Sickle cell disease is often detected early through routine newborn screening. Providers may also use blood tests to evaluate red blood cells and confirm the diagnosis.
A specialized test called hemoglobin electrophoresis helps identify the type of hemoglobin in the blood and determines whether someone has the disease or carries the gene.
How is it treated?
Treatment focuses on managing symptoms, preventing complications, and improving quality of life.
Common approaches include:
- Medications to relieve pain during flare-ups
- Staying well-hydrated to reduce the risk of pain episodes
- Preventive care such as vaccines and antibiotics
- Medications like hydroxyurea to decrease symptom frequency
- Blood transfusions for severe anemia or complications
In certain cases, a bone marrow or stem cell transplant may offer a potential cure. This option is typically considered for younger patients with severe disease and a suitable donor.
Because sickle cell disease is lifelong, ongoing care and regular checkups are essential. Healthy habits like staying hydrated, eating well, and avoiding extreme temperatures can help reduce complications.
