Hi.
Thanks for your query.
Noted the history about your friend and understood your concerns.
Distension of abdomen to the size of kid's football in upper abdomen, nausea, burping and lots of gas in your friend indicate that there is an
intestinal obstruction unless proved otherwise.
Hence I would advise her the following in such a situation:
Take her to ER or at least a Family Physician for clinical evaluation, examination and investigations.
X-ray of abdomen in standing position,.
Ultrasonography.
Tests of blood, stool and urine.
All these will lead to an appropriate diagnosis for planning a proper management.
This can not be due to H pylori.
She may need surgery if there is no obstruction that does not respond to medical management for three days.
IF no acute obstruction but other causes like acidity related problems with or without intestinal infection she will need a course of an antibiotic,
metronidazole, probiotics, activated charcoal tablet, PPI like
Omeprazole and
Domperidone to regularize the bowel movements.
