When you poop and pee at the same time it usually means that you've developed a colovesical fistula.
A colovesical fistula is an abnormal connection between the colon and urinary bladder.
Although they are uncommon, CVFs can cause significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis.
The most common cause of colovesical fistula is diverticulosis; however, it may be caused by malignant diseases, Crohn's disease, radiation, etc.
The underlying mechanism is the direct extension of a ruptured diverticulum or secondary erosion of a diverticular abscess into the bladder
Colovesical fistulae can almost always be treated with resection of the involved segment of colon and primary reanastomosis.
Fistulae due to inflammation are generally managed with resection of the primarily affected diseased segment of intestine, with repair of the bladder only when large visible defects are present.
The goal of conservative treatment is for the fistula to close and heal on its own.
However, surgery may still be necessary in cases where the fistula does not heal on its own.
Because colovesical fistula may be a complication of diverticulitis, make sure you follow the doctor's orders in treating diverticular disease.
Fistula tracts must be treated because they will not heal on their own.
There is a risk of developing cancer in the fistula tract if left untreated for a long period of time.
Most fistulas are simple to treat. Either the tract or fistula can be opened or the tract and the pocket inside are completely removed.
However in some cases when you pee and poop at the same time it can also just mean that you have a weak bladder and or weak bowels.
And sometimes it's normal to pee and poop at the same time if you both need to pee and poop.
If you're suddenly having to pee and poop at the same time and it occurs too often then you should see a doctor about it just to be sure nothing serious is going on.
