How is lapband and gastric bypass differant when they work the same way?
Question:
Answers:
Lapband is a small band surgically attached around your stomach to prevent you from eating too much at one time. However, it does not restrict the type of food you eat (i.e. sugar). Over time time band may have to be filled to maintine the size of your stomach. Gastric bypass (roux-n-Y in particular) reduces the size of your stomach and length of intestine during a surgical proceedure. One of the ways it helps you loose weight is to reduce the size of your stomach like the lapband but it also causes dumping syndrome. Early and late dumping has been reported in patients after this procedure. Dumping is caused by rapid passage of food from the pouch into the small intestine. Before surgery, the stomach has a valve at the top and bottom, and serves as an acid-filled storage tank, breaking food intake down into small, component parts and passing it to the small bowel in increments. After surgery, food passes directly into the small bowel, mixed only with saliva and amylase from the mouth, but no stomach acid. The molecules (component parts) of the food remain fairly intact and therefore, large. The small bowel responds by diluting what we eat through a process of ‘water recruitment’ into the bowel space. The ‘richer’ the food, in terms of molecule size or sugar content, the more water will rush into the small bowel to dilute it. This is referred to as ‘early dumping.’ Suddenly, the heart will pound and beat rapidly; you may feel dizzy, and overwhelmingly tired. The bowels may gurgle and churn, and will feel bloated and gassy. This might be followed by loose stools and even vomiting. It is not dangerous, but it can be frightening to the uneducated patient. ‘Late dumping’ is caused by an insulin response to the ingested food. One might feel flushed, sweaty, fatigued, and experience all the signs of hypoglycemia (low blood sugar).
Either way you go as long as you follow the after-proceedure care and plans you should do very well.
They have the same effect, however the gastric bypass is a permanent surgery and the lapband is adjustable and removable.
Hi,
They are totally different, and the effects are also different. With the band you restrict the food intake, so loosing weight. With the gastric bypass you restrict the size of the stomach and you bypass part of the intestines.. in a nutshell, you eat less and you absorb less calories.
I would strongly suggest you talking with your doctor to choose methodology that would suit you best.
