Fajr Eutsey Across the United States, about one hundred thousand people live with sickle cell disease. The CDC reports that the condition can shorten life expectancy by more than twenty years, and many people don’t receive the care that could help prevent serious complications. Most of us never think about our blood. It moves through the body, carrying oxygen to every organ and muscle. Because it works in the background, it is easy to forget how much depends on it. Learning about sickle cell disease helps communities and healthcare providers understand what this condition does inside the body and how to support the people who live with it every day.
What Is Sickle Cell Disease?
Sickle cell disease is a blood condition that changes the shape and movement of red blood cells. According to Cleveland Clinic, the hemoglobin inside these cells is different, causing them to become firm and curve into a C shape. Curved cells can stick together and slow blood flow, making it harder for oxygen to reach the parts of the body that need it.
When oxygen delivery drops, the body works harder. This can lead to pain, tiredness, swelling, and other health problems. The condition affects everyone differently. Some people experience symptoms often, while others have them occasionally.
Sickle cell disease is inherited. A person is born with it when they receive certain genes from their parents. It is not contagious, and nothing a person does causes it to develop later in life.
Different Types of Sickle Cell Disease
According to the CDC, sickle cell disease has several types. The type a person has depends on the hemoglobin genes they inherit from their parents. Hemoglobin is the part of red blood cells that carries oxygen.
Hemoglobin SS
This is the most common type. A person inherits two hemoglobin S genes. It is often called sickle cell anemia and is usually the most severe form.
Hemoglobin SC
A person inherits one hemoglobin S gene and one hemoglobin C gene. This type is often milder, but symptoms can still vary from person to person.
Hemoglobin S beta thalassemia
A person inherits one hemoglobin S gene and one beta thalassemia gene. Beta thalassemia is another condition that affects hemoglobin. Some people with this type have more severe symptoms. Others have milder symptoms. The severity depends on how strongly the beta thalassemia gene affects hemoglobin production.
Rare Types
Some people inherit one hemoglobin S gene and another gene that makes a different kind of hemoglobin, such as D, E, or O. These types are less common. The severity can vary from person to person.
Sickle Cell Trait
People with sickle cell trait inherit one hemoglobin S gene and one normal hemoglobin A gene. They usually do not have symptoms. In rare situations such as dehydration or very intense exercise, a person with sickle cell trait may develop health problems. People with sickle cell trait can pass the hemoglobin S gene to their children.
How Doctors Diagnose It
In the United States, doctors usually diagnose sickle cell disease at birth. Hospitals test newborns with a blood test. Doctors can also diagnose it before birth through prenatal testing. Early diagnosis helps families and doctors plan care and prevent complications.
How Sickle Cell Disease Is Managed
People with sickle cell disease can live full and active lives with the right care. Treatment focuses on keeping blood flowing smoothly and preventing complications. This can include staying hydrated, avoiding extreme temperatures, taking medicines that help blood cells work better, and getting regular checkups.
Some people receive blood transfusions. Some take medicines that reduce the chance of pain flares. A few may be candidates for bone marrow transplants or newer gene therapies. Care plans are personal and depend on each person’s needs.
Life with Sickle Cell
Children and adults with sickle cell disease can learn, work, play, travel, and build families. Some days may call for extra rest or specific dietary goals, and every journey looks a little different. Support from family and friends can help. Living with sickle cell disease can be challenging, but it doesn’t take away a person’s abilities or dreams. If you or someone you know is living with sickle cell disease, a little understanding can make a big difference.
