Bariatric Surgery

Bariatric surgery is an option for people who are severely obese and cannot lose weight by traditional means or who suffer from serious obesity-related health problems. The operation promotes weight loss and reduces the risk of type 2 diabetes by restricting food intake.

What is Bariatric Surgery?

Exercise and diet alone often fails to effectively treat people with extreme and excessive obesity. Bariatric surgery is an operation that is performed in order to help such individuals lose weight. Evidence suggests that bariatric surgery may lower death rates for patients with severe obesity, especially when coupled with healthy eating and lifestyle changes after surgery.

Bariatric surgery reshapes body fat and muscle more than GLP-1 drugs

Bariatric surgery and GLP-1 treatments reshape body composition differently, emphasizing the importance of sex and treatment choice in muscle preservation.

Postoperative complications of medical tourism place growing financial burden on the NHS

The postoperative complications of medical tourism may be costing the NHS up to £20,000 per patient, suggest the findings of a rapid review of the available data, published in the open access journal BMJ Open.

Weight loss normalizes fat tissue at cellular level

It is well known that obesity typically leads to inflammation and dysfunction of fat tissue that increases the risk of developing metabolic diseases such as diabetes and cardiovascular diseases.

Metabolic BMI reveals hidden health risks in normal weight individuals

People of normal weight may also be at risk of diabetes and similar diseases. A study from the University of Gothenburg reveals that those with an unexpectedly high so-called metabolic BMI have up to a five times higher risk level.

Weight loss drugs and surgery improve body composition in patients with obesity

Both the new weight loss drugs and bariatric (weight loss) surgery improve body composition in patients with obesity by inducing a moderate loss of fat-free mass (including lean muscle) along with a substantial reduction in fat, researchers at Vanderbilt Health have found.

Forever chemicals linked to higher liver disease risk in adolescents

A new study co-led by the Southern California Superfund Research and Training Program for PFAS Assessment, Remediation and Prevention (ShARP) Center and the University of Hawai'i has linked certain common "forever chemicals" to a higher risk of liver disease in adolescents.

Addressing unsustainable food systems can deliver double benefits for health and climate

A major review in Frontiers in Science highlights how tackling unsustainable food systems-reflected by our changing food environment-is urgent for both health and climate.

Higher PFAS levels reduce blood sugar improvements after teen bariatric surgery

A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin A1c (HbA1c), which measures average blood sugar levels over the past 60-90 days.

Brain recordings reveal why food cravings return despite tirzepatide

Researchers investigate the effects of tirzepatide on food preoccupation by influencing the brain’s mesolimbic circuitry.

Brain recordings reveal short-lived effects of tirzepatide on food cravings

A rare glimpse into the brain activity of a patient with obesity and loss of control eating on tirzepatide, marketed as Mounjaro and Zepbound, revealed that the medication suppresses signaling in the brain's "reward center" thought to be involved in food noise – but only temporarily.

Blood biomarkers forecast long-term blood pressure improvement after adolescent bariatric surgery

A groundbreaking study published in Hypertension, the journal of the American Heart Association, has identified a set of blood-based biomarkers that can predict improvements in blood pressure five years after adolescents underwent metabolic bariatric surgery.

Scientists revive diabetic beta cells, revealing a new path to restore insulin function

Researchers demonstrated that pancreatic β cells from type 2 diabetes donors can partially regain glucose responsiveness when cultured outside the diabetic environment. This recovery, driven by specific gene expression changes, identifies JAK inhibitors as potential therapeutic candidates to restore β-cell function.

Study finds surge in the use of weight loss drugs among bariatric surgery patients

New research findings show a significant increase in the use of weight loss drugs among patients undergoing metabolic and bariatric surgery, signaling an evolution in the management of obesity and Type 2 diabetes.

How much apple cider vinegar reduces weight? Meta-analysis points to 30 mL daily

A new meta-analysis of randomized controlled trials shows apple cider vinegar can modestly but significantly reduce body weight, BMI, and waist circumference in adults, particularly those with obesity or type 2 diabetes.

GLP-1 drugs may offer cost-effective treatment for people with knee osteoarthritis and obesity

A new study led by investigators at Mass General Brigham finds that adding novel weight loss GLP-1 drugs semaglutide and tirzepatide to usual care represents a cost-effective treatment strategy for people with knee osteoarthritis and obesity, with tirzepatide providing greater health benefits at lower cost compared to semaglutide.

Ketogenic diets may lower migraine frequency and medication use

This narrative review argues that the migraine brain is hypometabolic, with converging evidence of mitochondrial dysfunction, impaired glucose handling, neuroinflammation, microbiome shifts, and obesity-related pathways. It proposes ketogenic diets as a plausible preventive strategy that may reduce monthly migraine days and medication use, while emphasizing the need for larger, rigorous randomized trials and careful clinical oversight.

Increasing numbers of bariatric surgery patients turn to GLP-1 drugs

Bariatric surgery is usually effective on its own for weight loss, but an increasing proportion of patients who undergo bariatric surgery start taking one of the new glucagon-like 1 peptide receptor agonist (GLP-1) weight-loss drugs in the years after their surgery, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health.

PFAS exposure increases risk of weight regain after adolescent bariatric surgery

Adolescents who undergo bariatric surgery face a higher risk of weight regain, which can undermine treatment success and long-term health, if they have elevated blood levels of per- and polyfluoroalkyl substances (PFAS) prior to the procedure, according to new USC research.
