Detailed answer

Yes, dark spots can be a sign of an autoimmune disorder. Autoimmune disorders occur when the body's immune system mistakenly attacks normal healthy cells. In some cases, this immune response can result in the overproduction of melanin, the pigment responsible for skin color. This overproduction can lead to the appearance of dark spots or patches on the skin, known as hyperpigmentation. It is important to note that dark spots alone are not conclusive evidence of an autoimmune disorder, as they can also be caused by other factors such as sun damage, hormonal changes, or age. If you suspect an autoimmune disorder, it is crucial to consult with a healthcare professional for accurate diagnosis and appropriate treatment.
