How To Get Rid Of Divarication Of Recti

I was diagnosed yesaterday as having a divarication of recti. I have read oon the internet that this can be corrected sugically but usually this is not necessary. I am not skinny but wouldn't have considered my self obese which I undeerstand is the usual source for a 54 yr old man. I am 6'1" and weigh 245#. Besides surgery is there anything I can do to get rid of this issue: weight loss, exercise, sit-ups, etc...
