Types of Sickle Cell Disease

Types of Sickle Cell Disease

Not everyone with sickle cell disease has the exact same type. There are actually a few different types, and the type you have depends on the genes you inherited from your parents. Some types cause more severe symptoms than others, but all of them are manageable with the right care and knowledge.

Here is a simple breakdown of the most common types:

HbSS (Sickle Cell Anemia)

This is the most common and usually the most severe type of sickle cell disease. It happens when you inherit a sickle cell gene from both parents. People with HbSS tend to experience more frequent pain episodes and complications. When people talk about sickle cell disease in general, they are usually referring to this type.

HbSC

This type happens when you inherit one sickle cell gene from one parent and a different abnormal hemoglobin gene called "C" from the other parent. HbSC is generally considered milder than HbSS, but it can still cause serious complications. Do not let the word "milder" fool you into thinking it does not need attention, because it does.

HbS Beta Thalassemia

This type happens when you inherit one sickle cell gene from one parent and a beta thalassemia gene from the other parent. There are two versions of this type. HbS Beta Zero Thalassemia tends to be more severe, similar to HbSS. HbS Beta Plus Thalassemia tends to be milder. Your doctor can tell you which version you have.

Rarer Types

There are also rarer types like HbSD and HbSE. These happen when the sickle cell gene is paired with other less common abnormal hemoglobin genes. They are less common but still important to understand if that is your diagnosis.

What does my type mean for me?

Knowing your type helps you and your doctors create the best plan for your care. It can affect how often you have pain crises, what medications work best for you, and what to watch out for. If you are not sure what type you have, ask your doctor. You deserve to know exactly what is going on in your own body.

No matter what type you have, one thing stays the same: knowledge is your superpower. The more you understand about your diagnosis, the better prepared you are to live your healthiest life.
