Long-term bariatric surgery (≥5 years) significantly reduces the incidence of macrovascular complications, cardiovascular events, and myocardial infarction in severely obese patients with type 2 diabetes compared to conventional medical therapy.
For severely obese individuals with Type 2 Diabetes, bariatric surgery offers significant long-term protection against heart attacks, strokes, and other cardiovascular complications compared to standard medical treatment alone. This benefit persists for at least five years post-surgery. While surgery is a major intervention, the data supports its use for reducing major cardiovascular risks in this specific population.
Patients in the bariatric surgery group as compared to the conventional treatment group had lower incidence of macrovascular complications (RR = 0.43, 95%CI = 0.27~0.70), cardiovascular events (CVEs) (HR = 0.52, 95%CI = 0.39~0.71), and myocardial infarction (MI) (RR = 0.40, 95%CI = 0.26~0.61).
Why this rating
Meta-analysis of 4 RCTs and 6 cohort studies with long-term follow-up (5-20 years), though heterogeneity was high in some metrics.

More from this paper
- Bariatric surgery leads to greater long-term weight loss and better glycemic control (lower HbA1c, HOMA-IR) compared to conventional medical therapy in severely obese T2DM patients, with specific surgical types (RYGB, BPD) showing superior metabolic effects.Good
- Bariatric surgery does not significantly reduce all-cause mortality compared to conventional medical therapy in severely obese T2DM patients over the long term, although it reduces specific macrovascular events.Moderate

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
