The time it takes for autoimmunity to develop can vary widely depending on the specific autoimmune disease and individual factors. In some cases, autoimmunity can develop over months or years, while in others, symptoms might appear more rapidly.
Autoimmune diseases often result from a combination of genetic, environmental, and hormonal factors, and the onset can be influenced by these elements. For some conditions, like Type 1 diabetes, symptoms can appear relatively quickly after the immune system starts attacking insulin-producing cells. For others, such as rheumatoid arthritis or lupus, the process may be more gradual, with symptoms developing slowly over time.
