Hi, how are you doing today ?
As for your question , the condition you are presenting with may be either inflammatory bowel disease or
gluten sensitivity syndrome.
So ask the doctor to take a biopsy of the gut and examine for gluten sensitivity or any other food allergy .
Gluten is a malt protein present in many of our day to day food products , so if she is having that then just
avoiding such foods itself will cure her.
Lactulose solution is a synthetic sugar which is used in patients with constipation or in liver disease.
Go for a thorough full body testing including colonoscopy, spinchter pressures, blood testing and
electrolytes.
Hope this clears out your question, hope to converse with you again.
Have a nice day.
