The diastasis repair is going to be by plication: since he has actually lost 70+ lbs from his highest weight (which was 12 years ago) and 30+ lbs in the last 6 months, there shouldn't be as much pressure on his poor fascia. But there is a risk - noting the recurrent inguinal hernia on the right, the new hernia on the left, the umbilical hernia and the diastasis, the surgeon remarked that his fascial integrity sucks - she even poke me in my incisional hernia (remember, I'm 11 years post-op and it just showed up) and said I had better fascia than he does, genetically, and because he smoked heavily. It could come back - I hope they sew him up good and tight.
