What exactly is hemophilia—and why can a seemingly minor injury become a serious medical concern? In this Rehealthify video, we break down hemophilia in a clear, easy-to-understand way, including Hemophilia A vs. Hemophilia B, symptoms, genetic causes, diagnosis, treatment options, and inhibitors that can interfere with treatment. Hemophilia is a bleeding disorder in which blood doesn't clot properly. The two most common inherited forms are Hemophilia A, associated with low levels of clotting factor VIII, and Hemophilia B, associated with low levels of clotting factor IX. We'll explain what's happening inside the body—and why bleeding into joints, muscles, or other tissues can be an important complication. ⏱️ CHAPTERS 00:00 — Hemophilia: What You Need to Know 00:32 — Overview 01:14 — Types A and B 01:39 — Signs and Symptoms 02:31 — Who Is at Risk? 03:20 — Causes 03:39 — Diagnosis 04:38 — Treatment 05:20 — Inhibitors to Treatment Products 05:59 — Key Takeaways & Summary 06:36 — Final Takeaway & Subscribe 🩸 Hemophilia A vs. Hemophilia B The distinction is important: Hemophilia A → Factor VIII deficiency or low factor VIII Hemophilia B → Factor IX deficiency or low factor IX The amount of clotting factor in the blood is also used to determine the severity of hemophilia. 🧬 Is hemophilia genetic? Most inherited hemophilia is related to changes in genes involved in producing clotting factors VIII or IX. These genes are located on the X chromosome, which is why inherited hemophilia occurs much more frequently in males, although females can also have hemophilia and can experience bleeding symptoms. 🧪 How is hemophilia diagnosed? Diagnosis generally involves blood testing to determine whether blood is clotting normally, followed by specific clotting-factor tests, also called factor assays. These tests can help determine the type and severity of hemophilia. 💉 How is hemophilia treated? Treatment can include replacement of the missing clotting factor, preventive treatment known as prophylaxis, non-factor therapies for certain patients, and gene therapy for appropriate patients with Hemophilia A or B. Treatment decisions should be individualized with qualified healthcare professionals experienced in bleeding disorders. ⚠️ What are inhibitors? One particularly important complication is the development of inhibitors. Inhibitors are antibodies that interfere with clotting-factor treatment, potentially making bleeding episodes more difficult to control. The CDC reports that approximately 15%–20% of people with inherited Hemophilia A or B develop an inhibitor.
