NASH is a disease without a therapy. It's a situation where there's an inflammatory response in your liver. Type 2 diabetes and obesity are our large contributors to this, and sometimes you can have obesity and Type 2 diabetes and you'll never develop liver disease. And sometimes, all of a sudden, you will develop an inflammatory response that will cause scar tissue formation in your liver and that can lead to liver failure. That's kind of what NASH is and there's no therapy. And because there's no therapy, doctors under-diagnosed, because what's the point in diagnosing you?
