Gastric Bypass in Obesity

Stenosis in gastric bypass for morbid obesity.

veloped by many patients with morbid or severe obesity secondary to hyperinsulinism, renders subjects at risk of cardiovascular disease. This, together with osteoarticular disease from overload, sleep apnea, and a long list of potential comorbidities, progressively impairs quality of life with a significantly reduced lifespan. Health resource use because of this condition has grown exponentiall...

Comparison of roux-en-y gastric bypass techniques with and without distal gastric plication in patients with morbid obesity

Human gut microbiota in obesity and after gastric bypass.

Recent evidence suggests that the microbial community in the human intestine may play an important role in the pathogenesis of obesity. We examined 184,094 sequences of microbial 16S rRNA genes from PCR amplicons by using the 454 pyrosequencing technology to compare the microbial community structures of 9 individuals, 3 in each of the categories of normal weight, morbidly obese, and post-gastri...

Neurologic complications of gastric bypass surgery for morbid obesity.

BACKGROUND The number of bariatric procedures is rapidly growing as the prevalence of obesity in the USA is increasing. Such procedures are not without complications, and those affecting the nervous system are often disabling and irreversible. We now describe our experience with these complications and review the pertinent literature. METHODS We describe 26 patients with major neurologic cond...

Hyperinsulinemic hypoglycemia following gastric bypass surgery for obesity

Purpose of review To examine the recently recognized association between bariatric surgery-induced weight loss and postprandial hyperinsulinemic hypoglycemia. Recent findings Postprandial hypoglycemia following gastric bypass for obesity is generally considered a late manifestation of the dumping syndrome and can usually be managed with dietary modification. A rare syndrome characterized by mor...
