Meatal stenosis have many causes, one of them being (which I want to inform you) ischemia
to the artery and resulting in inflammation. The same can occur to intestines resulting in ischemic colitis
. Get some endoscopy
test and WBC and serum electrolytes for differential diagnosis. Give more water and ORS and consult a Gastroenterologist
if the symptoms persists and sever.
Have a good health, Thank you.
