My wife has an incredibly difficult time passing bowels for as long as I have known her (9 years). She takes Miralax daily, and if she even skips one day she may not poop for several days in a row.
I wish it were as simple as that. Unfortunately, Miralax won't clear everything out, it will just make her pass enough to not feel so bloated she can't eat. The remainder of bowels stays in her, and she quite literally has a permanent visually obvious bloated state.
We have done a colonic cleanse one time in the past, and it was very effective and cleared everything out. Her abdomen was dramatically flatter and for the first time looked like the abdomen of a healthy person (she is not overweight). Unfortunately this only lasted a few days before the bowels built back up inside her.
She has tried high-fiber diets in the past with few results and she always drinks an incredible amount of water, so its not a matter of lack of fiber or dehydration. She simply doesn't poop and its been a mystery for almost her whole life. Has anyone experienced or heard of a situation like this?
