autoimmune diseases prevalence

Autoimmune diseases occur when the immune system mistakenly attacks the body’s own tissues, leading to chronic health issues. Their prevalence varies depending on the specific disease, but collectively, they affect about 5-8% of people worldwide, with women being more commonly diagnosed than men. Factors like genetics, environment, and lifestyle can influence risk. Some autoimmune conditions, like rheumatoid arthritis or Hashimoto’s thyroiditis, are relatively common, while others are rare. Overall, awareness and research continue to improve understanding and management, helping many individuals lead healthier lives despite these complex conditions.
