Take my strong hand <| sep |> It ' s pretty amazing how little this has been studied . In the late 70 ' s and early 80 ' s right after RNY started becoming more widely available for weight loss there were a couple , but since then almost nothing . The only study I could find that supports the claim but not the numbers actually states that WLS improves marital satisfaction during the 3 years after WLS . It notes that marital satisfaction starts off about 5050 before surgery which is higher dissatisfaction than in the normal population but then improves postop year to year and winds up being about normal 3 year out . But in seeming contradiction to that satisfaction rating , a slightly higher divorce rate occurs within 3 years postop . They note that the divorces are more common in marriages that were rated as troubled before WLS . So seemingly , WLS improves satisfaction in most marriages but exacerbates preexisting marital discord . Now bear in mind this was 54 RNY patients in 1982 . Hardly definitive today .
