What Is IgG4-Related Disease?

IgG4-RD is a rare, lifelong disease that can progress silently over time. The body's immune system mistakenly turns on itself, causing damage to organs and tissues that are otherwise healthy. Understanding how organ damage can cause symptoms is important in the timely diagnosis of IgG4-RD.

IgG4-RD can affect different parts of your body, and its symptoms may resemble those of other conditions. Learning more about IgG4-RD can help you manage your health and advocate for yourself.
