info_outlineIn this episode, Therese Markow and Dr. Fred Miller discuss the autoimmune disease epidemic, highlighting the economic burden and the rise of diseases like juvenile diabetes, lupus, and multiple sclerosis. Dr. Miller explains that autoimmune diseases occur when the immune system attacks the body, affecting various organs. He notes that there are at least 150 types of autoimmune diseases, with prevalence rates varying from 0.1% to 5% of the population - the exact number is unknown due to the need for better registries to track these diseases.

He also mentions new treatments and the importance of lifestyle changes in prevention and management.
Key Takeaways:
-
Virtually any organ system or tissue in the body can be damaged by the immune system, which makes autoimmune diseases difficult to assess, diagnose, and treat, as they can be so varied from person to person, and they can change over time.
-
There are no fully agreed-upon definitions for autoimmune diseases. As such, we don’t know how many there are, but most experts would say at least 150 different types.
-
All of the autoimmune diseases are developed from interactions of many genes and many environmental risk factors in combination.
-
Various environmental exposures might not change the genes themselves, but they might alter the normal way that genes are supposed to be turned on and off.
"We really don't have a way to measure all of these yet, but we are expanding the range of the types of exposures we can measure every year, and there are a few ways of capturing which exposures or mixtures of them we've experienced at what times, and by integrating all these together into a single number, this could help us understand the cumulative exposures that are that are probably important for the development of these diseases." — Dr. Fred Miller
