This is a long shot but wth... There was a Maury Povich show from the mid-90s featuring a woman named Happy Leuken (seriously). I've googled her and the only hit is from a book where she's mentioned as an aside, the writer rightfully disgusted by the state of television at the time and society as a whole.
Anyway the show was classic late 20th century sideshow exploitation, Happy a very large, very pear-shaped woman married to a military officer. She was bedbound and the show was about getting her to a treatment center in Boston with the assistence of several soldiers (ungh). So it was sort of a proto-My 600lb Life, but unlike that shitshow, Happy was... happy, and pretty upbeat about life, except that she, you know, couldn't walk. And this being a show about a fat woman the mid-90s, Richard Simmons showed up to help save the day.
I found these screen grabs a while back but it's all I've got. (First 3 are Before, last 2 are After.) I remember there was more to it and would be profoundly grateful to anyone who has the vid, knows where I can find it, or has any further info on Happy herself.
As a bonus, and to maybe kick off a lost TV clip archive thread, here's an old Discovery doc featuring megapear Deborah Harper aka Whimsical Angel:
