Hi.
Thanks for your query and an elucidate history.
Hi
Peritoneal dialysis is being done for such a long time, there is a possibility of
peritonitis.
As per your history the other causes can be :
Intestinal infection as you are more prone to.
Increased urea and
creatinine also can cause changes in the intestinal movements, predispose to infection.
I would suggest you the following:
First of all get the stool tested for routine, microscopy and culture and sensitivity.
Secondly get started on appropriate antibiotics as per your
kidney function reports under the guidance of a
Nephrologist.
Get other blood tests to see for CBC, Kidney, liver function test.
X-ray of the abdomen in standing position.
The proper diagnosis can lead to a proper treatment and you will be fine.
