Knowra Bariatric surgery Bariatric surgery Bariatric surgery comprises operations that treat obesity by changing digestive anatomy, food intake, nutrient absorption, or metabolic signaling. Procedures differ in how they produce weight loss and affect obesity-related disease.
Roux-en-Y gastric bypass : An operation that creates a small stomach pouch and reroutes the small intestine. It combines restriction and intestinal rerouting, with substantial effects on gut hormones.
Obesity : A chronic disease characterized by excess or dysfunctional body fat that can impair health. It is the condition bariatric procedures are designed to treat.
Anti-obesity medication : Prescription drugs used alongside lifestyle measures to reduce excess body weight or its health effects. Medication can treat obesity without permanently altering digestive anatomy.
Dumping syndrome : A group of symptoms caused by rapid movement of food from the stomach into the small intestine. Some operations can cause it after meals, especially those rich in sugar.
Long-term outcomes of bariatric surgery : Health, weight, and survival outcomes measured years after bariatric procedures. Long follow-up clarifies durability, late complications, and effects on chronic disease.
Sleeve gastrectomy : An operation that removes much of the stomach, leaving a narrow tube-shaped stomach. It reduces stomach volume and changes appetite signaling without bypassing the intestine.
Type 2 diabetes : A metabolic disease in which insulin resistance and inadequate insulin secretion cause high blood glucose. Bariatric procedures can improve diabetes, sometimes before major weight loss occurs.
Lifestyle medicine : Clinical care that uses nutrition, physical activity, sleep, and behavioral change to prevent or treat disease. Lifestyle treatment remains necessary, but does not involve an operation.
Micronutrient deficiency : A shortage of essential vitamins or minerals in the body. Reduced intake or absorption can require lifelong supplementation and laboratory monitoring.
Bariatric surgery eligibility : Clinical criteria and individualized assessments used to determine suitability for bariatric procedures. Eligibility standards continue to evolve beyond thresholds based solely on BMI.
