Noted the history about your daughter suffering from pain in abdomen and nausea for three weeks.Ultrasonography
is normal for gallbladder
and appendix. Ultrasonography can miss on many disease as these can not be seen like colon, intestines.
Hence I would advise her the following:w
Send the stool and blood samples for tests.
If there is any evidence of an intestinal infection then a prescription based course may help a lot.
Add on antispasmodic and probiotic
If there pain still persists and additional CT scan of abdomen and colonoscopy
along with upper GI Endoscopy may be required.
Further management can be done as per the findings and thus get properly cured.
If all the investigations are normal then a possibility of IBS that is irritable bowel syndrome
to be kept in mind and treated accordingly.
Also ask her to watch for the foods and beverages that cause problems and stop these altogether.
Hope I have answered your query. Let me know if I can assist you further.
