Thanks for posting your query.
With the available described symptoms, there could be possibility of acute gastroenteritis
or chronic pancreatitis
Presence of recently diagnosed diabetes
with abdominal pain
suggest the diagnosis.
As he has increased frequency of defecation, possibility of gastroenteritis should also be kept in mind.
You should consult with internal medicine specialist and should go for thorough check up.
He should also go for complete blood count
, serum amylase and lipase, CT/ MRI scan abdomen and renal function test.
He should also go for endoscopy for better clarification.
He should take complete antibiotic therapy, antispasmodics and proton pump inhibitors.
He should take Tramadol when ever needed.
