Factor IX is a protein used to treat which condition?

Explanation:
Factor IX is a coagulation protein essential for proper blood clotting. When it’s missing or deficient, as in hemophilia B, the intrinsic coagulation pathway can’t generate enough thrombin to form a stable clot, leading to excessive bleeding. Replacing Factor IX with a concentrate brings back the missing component, restoring the clotting cascade and helping stop bleeding. That made-for-therapy relationship is why Factor IX is used to treat haemophilia. The other conditions listed—diabetes, anemia, and hyperlipidemia—are not about the coagulation cascade, so Factor IX wouldn’t be used for them.
