Combination therapy using GLP-1 receptor agonists with other hormones (GIP, GCG, or PYY) mimics the beneficial hormonal effects of gastric bypass surgery in non-surgical patients.
New combination drugs that activate multiple gut hormone receptors (like GLP-1, GIP, and Glucagon) are showing strong results in clinical trials for weight loss and blood sugar control, offering a non-surgical alternative to gastric bypass.
GoodSupportsHIGH confidence
Therefore, combination therapy is currently considered as the way to go to mimic the beneficial effects of RYGB surgery in a non-surgical manner [143].
Why this rating
Multiple clinical trials (Phase I/II) are cited showing promise for various combination therapies.

- Roux-en-Y gastric bypass (RYGB) surgery restores gut hormone balance by elevating postprandial GLP-1 and PYY levels, which contributes to sustained weight loss and improved glucose homeostasis.Good
- Obesity is associated with altered nutrient sensing mechanisms in the gut, specifically region-dependent changes in the expression of amino acid and bitter taste receptors, which may contribute to inconsistent gut hormone fluctuations.Moderate

- 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
