A Minimally Invasive Endoscopic Procedure Instead of Bariatric Surgery?

Endoscopic sleeve gastroplasty (ESG) delays gastric emptying, induces early satiation, and significantly reduces body weight, researchers report in the January issue of Clinical Gastroenterology and Hepatology. ESG could therefore be an alternative to bariatric surgery for some patients with obesity. Although bariatric surgery is the most effective therapy for obesity,

How Much Do Antibiotics Increase Risk of Obesity in Young Children?

Administration of 3 or more courses of antibiotics to children younger than 2 years greatly increases their risk for early childhood obesity, researchers report in the July issue of Gastroenterology. Antibiotics have been used to promote weight gain in the agricultural industry for decades. This effect is believed to be

Advances in PSC, NAFLD, and Liver Transplantation for Patients with HCV Infection reported at International Liver Congress

A chemical cousin of an existing drug shows promise for patients with primary sclerosing cholangitis (PSC), a larger waistline increases risk for severe nonalcoholic fatty liver disease (NAFLD), and livers from hepatitis C virus (HCV)-infected donors are safe for transplant into HCV-infected recipients were all among the exciting findings reported

  • A Brain Enzyme That Controls Satiety

A Brain Enzyme That Controls Satiety

Researchers identified a brain enzyme that regulates how much food mice eat in one sitting—deletion of this enzyme caused the mice to increase their food intake to the point of becoming obese. The results could provide new therapeutic target for human obesity. To study brain mechanisms that control meal size

  • What Changes Occur in the Intestine After Gastric Bypass vs Vertical Sleeve Gastrectomy ?

What Changes Occur in the Intestine After Gastric Bypass vs Vertical Sleeve Gastrectomy ?

The intestine adapts differently to Roux-en-Y gastric bypass (RYGB) than to vertical sleeve gastrectomy (VSG), researchers show in the February issue of Gastroenterology. RYGB increases intestinal glucose disposal whereas VSG delays glucose absorption, but each reduces glycemia. Bariatric surgeries such as RYGB and VSG are the most effective ways to resolve

Obesity Appears to Contribute to Increasing Use of Prescription Drugs

Prescription drug use in the United States increased by 8% over a 10 year period, and users of 5 or more prescription drugs almost doubled. Increases in prescriptions for specific agents appears to reflect the growing need for treatment of complications associated with the increase in overweight and obesity. The

6000-Calorie Diet Reveals Mechanisms of Obesity-Linked Insulin Resistance

A study in which researchers place healthy individuals on 6000-calorie per day diets has identified biologic changes that take place during the early stages of obesity and could lead to insulin resistance. The study, published in the 9 September issue of Science Translational Medicine, pinpoints oxidative stress as the potential

  • Researchers Determine how FTO Variant Increases Obesity Risk

Researchers Determine how FTO Variant Increases Obesity Risk

Variants in the FTO gene have been associated with obesity and metabolic disease, but little is known about the function of its product. Researchers now show how this gene regulates body weight. FTO encodes a nuclear protein of the AlkB related non-heme iron and 2-oxoglutarate-dependent oxygenase superfamily. In the NIH

  • What Causes Different Types of Fatty Liver Disease?

What Causes Different Types of Fatty Liver Disease?

Hepatic steatosis and steatohepatitis are increasing in prevalence, and can progress to histologically identical, more severe liver disease. They are associated with 3 main factors: alcohol, obesity or metabolic syndrome, and exposure to toxins. Researchers review the similarities, differences, and pathogenic mechanisms of alcohol-associated steatohepatitis (ASH), nonalcoholic steatohepatitis (NASH), and toxicant-associated fatty liver

What is This Liver Tumor?

Researchers describe a rare liver tumor of vascular origin in the May issue of Clinical Gastroenterology and Hepatology. Laisa Socorro Briongos-Figuero and Tomás Zamora-Martínez describe the case of a 59-year-old man with chronic pancreatitis who was was admitted to the hospital with vomiting and jaundice, without fever or diarrhea. He had a previous history of
