Thanks for posting your query.
With the available described symptoms, there appears to be possibility of acute gastroenteritis
or exaggerated gastrocolic reflex.
This problem may be due viral infection in duodenum
or due to hyperactive duodenum and food is pushed immediately further without absorption.
You should consult with internal medicine specialist and should go for thorough check up.
You should take complete antibiotic course, probiotics and antispasmodics.
You should also go for endoscopy
and duodenal biopsy
