If left untreated, scleroderma can lead to serious complications, including difficulty breathing, digestive issues, and even kidney failure. As the skin becomes tight and thickened, it can severely limit movement, causing pain and stiffness in the joints. The internal organ involvement can become even more severe, leading to organ failure if not properly controlled. Dr. Anu Daber emphasizes that without timely treatment, scleroderma can progress rapidly, making it harder to manage and increasing the risk of long-term complications.
