Changes in Ghrelin Levels
Although LRYGBP+FR was associated with lower fasting ghrelin levels at 6 and 12 months, following LRYGBP, fasting ghrelin levels were progressively elevated at 6 and 12 months. However, these results did not manage to reach statistically significant levels (p>0.05). Postprandial AUC ghrelin levels were not significantly changed after both procedures. At 12 months, LRYGBP+FR indicated lower, albeit non-significant, AUC levels, compared to LRYGBP (Figs.
