Greetings from healthcaremagic.com
I have gone through the case scenario of your wife and i do believe we need to rule out gall bladder
pathology primarily for her though any pathology from intestine, liver , pancreas
and heart may present in this fashion.
I do believe she has to undergo an ultrasonography
of the upper abdomen ( please take a note-- the interpretation of the exam will depend exclusively on her preparation ) to see if there is gall stones
, sludge or mucocele
of gall bladder.
Women in late thirties who are over weight and sometimes who are not over weight too can land up at the Emergency with pain in right abdomen either radiating to upper abdomen or the lower abdomen due to gall stones.
Surgery is the treatment of choice for gall stones .
Long term patients with gall stone may suffer from gall bladder carcinoma , so please do get an appointment with her physician at the earliest.
Hope my information is useful to you.
