When and why doctors divorce

I was just reading an article by Dr. Oz on Yahoo. And it occured to me that I had not written a post yet, in six years, about doctors and divorce. I know I wrote one about dentists and divorce, and lawyers and divorce, but not doctors and divorce. I did some research and I found this website called the National Review of Medicine which you can access here:

The author gave some very useful information about why doctors may get divorced, and also she offered tips on how to help doctors have stronger marriages and avoid divorce. To begin with, though, it seems that doctors as a group have a pretty low divorce rate, comparative to the rest of the population. It is well under 50% and doctors who marry other doctors have an even lower divorce rate, like less than 30%. So that is good to know. Also, the type of doctor may have some bearing on their likelihood of divorce. A psychiatrist, for example is more likely to end up divorced than a surgeon who is more likely to end up divorced than a pediatrician.
With doctors, what might be some issue? Well the long hours they work may drive them speedily to marital discord, I’m sure. As is the stress of the job. Psychiatrist in particular, must get pretty stressed with having to listen to everybody else’s stress and angst all day long. It just makes them slightly…nutty? Perhaps? By the time they get home? And then the last thing they want to deal with at home is problems and angst. And, of course, where can you expect to deal with problems and angst mostly if not at home?
In sum, I think if the average doctor wants a better chance at a life-long marriage, eschew psychiatry as a specialty, marry a fellow doctor and have a private practice where you can make your own hours. And as I said, doctors already have a pretty low divorce rate. So they really should be giving themselves a pat on the back when you get right down to it.
