What exactly is an autoimmune disease?

TV presenter Teigan Nash looks like she has the Instagram-perfect life - travels to exotic locations for work, is a regular on the red carpet and embraces hardcare adventures. Since 2018, she has been hiding an autoimmune disease (basically, it’s when the immune system attacks the body). In 2018, she was diagnosed with Crohn’s but it was only in late February that she announced her battle on social media. In her first interview since diagnosis, she reveals what an autoimmune disease actually is and how it’s changed her life.    WANT MORE FROM TEIGAN?   To hear today's full interview, where Teigan opens up about her journey to reach a diagnosis and how she manages her mental health...search for Extra Healthy-ish wherever you get your pods.  To find out more about Teigan Nash, check out her website, here, or Instagram @teigannash   WANT MORE BODY + SOUL?    Online: Head to bodyandsoul.com.au for your daily digital dose of health and wellness.
