What is a cousin to lupus?

A cousin to lupus is often considered to be other autoimmune diseases, particularly those that share similar symptoms and mechanisms, such as rheumatoid Arthritis, Sjögren's syndrome, and systemic sclerosis. These conditions, like lupus, involve an immune system that mistakenly attacks the body's own tissues, leading to inflammation and damage. They may also share certain risk factors, such as genetic predisposition and environmental triggers. Understanding these related conditions can help in diagnosis and treatment strategies for individuals with lupus.
