Autoimmune diseases occur when the body's immune system mistakenly attacks and destroys healthy body tissue. The exact cause of autoimmune disorders is unknown, but it is believed to involve a combination of genetic and environmental factors. Some factors that can cause an autoimmune disease include:

  1. Genetic Predisposition : Certain genes may make some people more likely to develop an autoimmune disease
  1. Environmental Triggers : Factors in the environment, such as viruses, certain chemicals, and sun exposure, may trigger an autoimmune disease in individuals who are genetically predisposed
  1. Gender and Hormonal Factors : Women develop many types of autoimmune diseases much more often than men, suggesting that hormonal and gender-related factors may play a role

While there are theories about why autoimmune diseases occur, the precise cause is not completely understood

. The interplay between genetic susceptibility and environmental triggers is thought to contribute to the development of these conditions
