There's a lot of times problems are occurring before you can see it on traditional lab markers. Um, this is like you said with the hypertension, this is a silent thing that's happening in the background are these elevated postprandial responses... So most of the time though, you can't feel these things going on and they're being missed by traditional markers, but there's problems occurring over and over. And so you really have to see the data to know what's happening inside your body.
