Autoimmune Disease Is Rising in Young People
Autoimmune disease isn’t just affecting older adults — it’s increasingly impacting teens, college students, and young professionals. In fact, a major NIH-supported analysis found that markers of autoimmunity in U.S. adolescents have tripled over recent decades. This means more young people are showing early immune system changes that increase the likelihood of developing an autoimmune disease.
This pattern is consistent worldwide. Global studies show a steady rise in autoimmune diagnoses among adolescents and young adults from 1990 through the 2020s, reflecting broader changes in the environment, infection patterns, stress, and immune vulnerabilities. While researchers are still exploring why this is happening, one thing is clear: today’s young adults are being diagnosed at higher rates than ever before.
The environment also affects how people manage their disease. For instance, extreme weather like heatwaves or storms can cause power outages. This is a problem for people who need to keep their medicine cold, like certain shots or insulin. Poor air quality can make it harder to breathe and increase tiredness in people with autoimmune conditions. As these problems happen more often, it becomes harder to keep symptoms under control.
Scientists are studying this link between the environment and autoimmune diseases more closely, hoping to find better ways to prevent and treat these illnesses. It’s important for patients to learn how their surroundings can affect their health. By staying informed, they can take steps to protect themselves—like keeping medicine safe during power outages, avoiding known triggers, or planning for bad weather. Understanding the environment’s role is an important part of living well with autoimmune disease.
