Gastric Banding Surgery for Teens Gastric banding is a form of bariatric surgery. It is used to treat people with severe obesity who have trouble losing weight through diet or exercise alone. Laparoscopic Adjustable Gastric Banding Laparoscopic adjustable gastric banding (LAGB) is one of the least invasive operations available for obesity. It is also one of the more effective. Laparoscopic Sleeve Gastrectomy Overview This surgery takes out the part of your stomach that curves outward, called the fundus.

Adjustable Gastric Band: What Happens If You Don’t Follow Your New Diet Food intolerance means that after surgery you may have problems eating foods that you once ate or that are part of your new diet. This can make it hard to stick to your new diet and keep the pounds off. Dumping Syndrome After Gastric Bypass Surgery Dumping syndrome is a problem for many people who have had gastric bypass surgery. It happens when the solid parts of a meal get “dumped” directly from the stomach into the small intestine without being digested. Iron Deficiency After Gastric Bypass Surgery Most of the iron from foods like meats, legumes, and iron-fortified grains is absorbed in the stomach and the first part of the small intestine. But after a gastric bypass procedure, food often bypasses this part of the body before minerals and vitamins can be absorbed. Afferent Loop Syndrome Afferent loop syndrome is a complication of stomach surgery. If you have had or are going to have a procedure called gastrojejunostomy, also known as Billroth II gastrectomy procedure, you should know that afferent loop syndrome most commonly occurs after this type of stomach surgery. Efferent Loop Syndrome After Gastric Bypass Surgery Efferent loop syndrome is one of two “loop syndromes” that can occur after some types of gastric bypass surgery. In a loop syndrome, a portion or “limb” of the small intestine becomes blocked. Risks of Bariatric Surgery: Anemia Anemia is a common side effect of weight-loss surgery. It’s a condition in which your blood contains lower than normal levels of red blood cells or red blood cells that contain too little of the protein hemoglobin. Risks of Gastric Bypass Surgery: Anastomotic Leaking One risk of gastric bypass surgery is that the anastomosis, the new connection created in your intestines during the bypass surgery, will leak. Leaking of digestive juices and partially digested food through an anastomosis is one of the most serious complications after bypass surgery. Stomal Stenosis After Gastric Bypass Surgery After a gastric bypass procedure for weight loss, some patients may have a narrowing of the new connection between the stomach and the lower intestine. This complication is called stomal stenosis. Problems with Digesting Fat After Weight-Loss Surgery Certain types of weight-loss surgery change the way your body deals with the nutrients in the foods you eat. This causes a rapid amount of weight loss, but also may lead to complications.
