And you will know it and you should understand it exactly as to how I'm telling you with diverticular disease. Let's begin. Diverticulum, generically speaking, means an outpouching. Whenever there's a weakness in the mucosa of that particular lumen then with increased intraluminal pressure of that particular structure you are then going to bring about or induce outpouching. Here, with diverticular disease, our focus will be in the colon. It's an acquired herniation of the mucosa and submucosa through the muscular layers of the colon which are the points of weakness. When inflammed, the diverticulum, which at first will be a diverticulosis; and this diverticulum, by the way, is a false diverticulum because you're not moving through all layers of the mucosa. And at some point, we'll talk about how feces gets trapped in your diverticulum, fecalith. And the diverticulosis, when there's enough of this fecalith accumulating. Imagine feces, you have a river of feces passing through your colon. You see that? River of feces. And then you have a diverticulum, why? Because you look like this, right? What happened? Low fiber–high fat diet. Years and years and years and years of the "Western diet," low fiber high fat diet. When you're sitting there on a toilet constipated as such that I just dramatically demonstrated then you have outpouching. So that was my interpretation or impression of constipation. And that outpouching then accumulates your feces and fecalith. Now this may then become infected. When it does so, you have now transitioned into diverticulitis.
