Is sjogrens a form of lupus?

Sjögren's syndrome and lupus are both autoimmune diseases, but they are not the same disease. Lupus is a systemic autoimmune disease that can affect many different parts of the body, including the skin, joints, kidneys, lungs, and heart. Sjögren's syndrome is an autoimmune disease that primarily affects the exocrine glands, which produce saliva and tears.
