! (and sorry for late reply- only just saw this)
pity enough ... it is still rather common to get a med bod that doesnt know the difference between being hypermobile and having hms, nor has a real understanding of EDS and its various forms
(lots of similar experiences/posts on here

)
if you feel up to doing something to educate that prof and her staff (I hope you do)... you could print out and send her this:
http://www.dwp.gov.uk/publications/spec ... -syndrome/(which includes info on gastrointestinal probs (as well as other non musculosceletal probs) being associated/being a sign/symptom of HMS)
and maybe so that she can see for herself (by comparing) why the DWP info includes "It is indistinguishable from Ehlers-Danlos Syndrome – Hypermobility type (previously known as Ehlers-Danlos type III)" this:
http://www.ncbi.nlm.nih.gov/books/NBK1279/and for more re the "indistinguishable" - she might want to look up a paper published in 2009 in the "american journal of medical genetics" titled
"The Lack of Clinical Distinction Between the Hypermobility Type of Ehlers–Danlos Syndrome and the Joint Hypermobility Syndrome (a.k.a. Hypermobility Syndrome)"
'authored' by Brad T. Tinkle (Cincinnati Children’s Hospital Medical Center, Cincinnati, Ohio), Howard A. Bird (University of Leeds, West Yorkshire, UK) , Rodney Grahame (University College Hospital, London, UK), Mark Lavallee (Memorial Sports Medicine Institute, South Bend, Indiana),
Howard P. Levy (Johns Hopkins University, Baltimore, Maryland), and David Sillence (Connective Tissue Dysplasia Management Service, The Children’s Hospital at Westmead, Westmead, New South Wales, Australia )
good luck!
