Clear liquid diet 4d how long b4 bowels r cleaned out. still passing stools small thin & mushy...cld that be from old trapped stuff hx: diverticulitis?

Old food: 4 days of a clear liquid diet results in no residual non absorbable products in small intestine. When this liquid material is partially absorbed in the 12 or more feet of colon which contains suface colonocyte cells and bacterial, it comes out as you describe as small thin and mushy. Has nothing to do with a resolved diverticular problem.
