Here are some other ways people could end up with autoimmune disease. It doesn’t always have to be genetic..
• Genetics – Family history raises risk; certain genes (like HLA variants) are linked to specific conditions such as type 1 diabetes, lupus, or rheumatoid arthritis.
• S*x – Women are affected far more often than men, especially during reproductive years, suggesting hormones (estrogen in particular) play a role.
• Infections – Some viral or bacterial infections can trigger autoimmunity, either by damaging tissue or through “molecular mimicry,” where the immune system confuses the body’s own cells with the pathogen.
• Environmental triggers – Smoking, certain chemicals, UV exposure, and pollutants have been linked to conditions like lupus and rheumatoid arthritis.
• Gut microbiome changes – Imbalances in gut bacteria are increasingly tied to immune dysregulation.
• Chronic stress – Prolonged stress can dysregulate immune function and may contribute to onset or flares.
• Diet and obesity – Highly processed diets and excess adipose tissue promote low-grade inflammation, which may increase risk.
• Certain medications – A small number of drugs can induce drug-related autoimmune reactions (e.g., some cases of drug-induced lupus).
