Research
Mixed
There is currently insufficient evidence to determine the specific impact of obesity on central blood pressure and its modification after bariatric surgery, as no studies have evaluated 24-hour central BP changes at medium or long term post-surgery.
While bariatric surgery lowers peripheral blood pressure, we do not yet know how it affects central (aortic) blood pressure over the long term. Future research is needed to understand if central BP improves as much as peripheral BP after surgery.
StrongRefutesHIGH confidence
An exhaustive review of the literature has not shown any study that had analyzed the modifications of the 24-h outpatient central BP after bariatric surgery at either medium or long term post-surgery.
Why this rating
The paper explicitly states the absence of studies.

More from this paper
- Bariatric surgery significantly reduces peripheral blood pressure and leads to hypertension remission in a majority of patients with morbid obesity, primarily through weight loss.Strong
- Central (aortic) blood pressure is a stronger predictor of future cardiovascular risk and target organ damage than peripheral (brachial) blood pressure because vital organs are more directly exposed to central pressure.Good

- 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
