Obesity And Depression Are Entwined, Yet Scientists Don’t Know Why

About 15 years ago, Dr. Sue McElroy, a psychiatrist in Mason, Ohio, started noticing a pattern. People came to see her because they were depressed, but they frequently had a more visible ailment as well: They were heavy.

McElroy was convinced there had to be a connection.

“Many of my [depressed] patients were obese. And they were very upset by obesity,’’ McElroy recalled. ”I looked into the literature, and it said there was no relationship. It didn’t make sense.” 

That sense of disconnect has started to change, promising new avenues for treatment, but also presenting a puzzle: Just how can you chart the mechanics of what ties the two together? And how can treatment be linked for two disorders that exist in totally different parts of the health care system?
