Hemophilia and joint bleeds: Preventing damage and preserving your future mobility

Hemophilia, a rare genetic disorder where blood doesn't clot normally, typically presents with symptoms, such as spontaneous bleeding in joints and muscles, frequent and difficult-to-stop nosebleeds, and bleeding gums. Joint health is key for the mobility and comfort of around 33,000 American males living with hemophilia. Joint bleeds can be painful and potentially debilitating for people with hemophilia.

Understanding hemophilia and joint bleeding

Joint bleeds, often affecting the knees, elbows, ankles, or hips, are characteristic of hemophilia. These bleeds may be spontaneous or result from seemingly minor injuries. In mild or moderate hemophilia, the symptoms of joint bleeds may not be immediately evident and sometimes may present as a mere tightness or tingling in the joint without pain or visible signs of bleeding. However, they can progress to joint pain, swelling, and reduced mobility, making early detection and treatment crucial for preventing long-term damage.

What causes joint bleeding in hemophilia?

When a joint undergoes stress during routine activities, the membrane lining the inner surface of the joint can bleed, particularly when pinched or stretched. Normally, the body’s clotting system quickly stops the bleeding. However, this bleeding continues in patients with hemophilia, and if left untreated, may lead to joint damage. The risk of bleeding increases with lower levels of clotting Factor VIII in the blood.

Who can experience joint bleeds?

Joint bleeding is a common symptom of hemophilia, which affects individuals irrespective of their severity. Patients with severe hemophilia often face chronic pain and disability as a result of joint bleeds.

Protect yourself from irreversible joint damage caused by hemophilia

Target joints and hemophilia

A "target joint" is one that experiences repeated bleeds, becoming a site of chronic concern. These joints are more susceptible to damage, leading to a reduced range of motion and chronic joint disease. The resulting pain and mobility issues can significantly impact daily activities.

It is imperative to seek prompt treatment for every joint bleed to mitigate the risk of joint damage. With the right management, people with hemophilia can lead fulfilling lives.

Factor VIII

Understanding the cause and signs of joint bleeds and seeking treatment are critical steps in preserving joint health and mobility in people with hemophilia. By staying informed and proactive, those affected by hemophilia can protect their joints and effectively manage them with their doctor.
