Hello!
Thank you for the query.
Pale or whitish stool with
abdominal pain and nausea can be caused by bile ducts obstruction due to gallstones. The pain should be present int he upper right or middle abdomen, radiate to the back. Urine should be dark.
The strang findings in the stool could be also undigested parts of the food. In such case pancreas disease should be also considered.
Sometimes such flecks in the stool can appear due to lots of bananas intake.
Other possible reasons of your symptoms are
intestinal inflammation due to bacterial or viral infection, partial bowels obstruction, inflammatory bowels disease.
I suggest you to visit your doctor and have some basic tests performed.
Abdominal X-ray, abdominal
ultrasound, blood work, liver tests (AST,ALT,GGTP),
bilirubin, amylase, urine amylase, urine analysis should be done at first. Depending of the results other tests and gastroenterologist consult might be necessary.
Hope this will help.
Regards.
