Psych. evaluation.  Munchausen Syndrome comes to mind.  And, I only watched the last 5 min. of the interview.

     So, the obese patient that was on tonight that has been undiagnosed and has had GI issues for a long time and ophthalmologic issues recently.  I did only catch the last few minutes of the episode but I think that she needs an intensive Psych. Evaluation. She appears to have Munchausen's Syndrome.
