Roux-en-Y Gastric Bypass (RYGB) and Laparoscopic Sleeve Gastrectomy (LSG) induce significantly greater cardiac reverse remodelling (reduction in left ventricular mass and concentric remodelling) than Laparoscopic Adjustable Gastric Band (LAGB) in obese patients.
If you are considering bariatric surgery for obesity, the type of surgery matters for your heart health. Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (LSG) are superior to Gastric Banding (LAGB) in reversing the structural changes in the heart caused by obesity. This benefit is driven by the greater reduction in visceral and epicardial fat, not just total weight loss. Discuss cardiac imaging and long-term heart health with your surgeon when choosing between these procedures.
RYGB and LSG appear to result in greater decreases in visceral adiposity, and greater reverse LV remodelling with larger reductions in LVM, concentric remodelling and pericardial restraint than LAGB.
Why this rating
Multicentre study with CMR (gold standard for cardiac structure), but small sample size for LAGB (n=10) and non-randomized assignment of surgery type.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
