Effects of MGB on Obesity-Related Co-Morbidities: Lipids, Hypertension, Non-Alcoholic Fatty Liver, etc.

  • Jean-Marc ChevallierEmail author


Data on effects of MGB on obesity-related co-morbidities are scarce. The metabolic syndrome is responsible for a high mortality in morbidly obese patients. In all reports, the type 2 diabetes (T2D) remission rate after MGB was between 80 and 90% at 2 years, and stable at 10 years, outperforming sleeve gastrectomy. Hypertension and hyperlipemia decreased between 70 and 80%. Severe OSA no longer required CPAP in more than 90% of the patients. Joint pain decreased also mainly, but vitamin D deficiency must be screened and supplemented. There are until now no data on the efficiency of the MGB on non-alcoholic fatty liver disease, but a recent article showed that MGB resulted in greater weight loss, with a transitional deterioration of several liver parameters in the first postoperative year, which was not associated with weight loss. In summary, MGB results in great improvement in dangerous obesity-related co-morbidities, such as T2DM, hyperlipemia, hypertension and joint pain, but requires continuing surveillance.
