Howdy Matthew!
Here is what Lap-Band does. It's a tiny band that is placed around your stomach in order to create what they call a "pouch". You can only eat 4-6 oz of food at a time or else it will make you sick. There are also food restrictions. However, doest prevent you from getting hungry most of the time too.
When the band is placed on your stomach they also put a port in your side. About once a month you go in for what they call a "fil"l. This is a simple shot of saline that is injected into the band around your pouch to make it tighter again. As you loose weight the band slips or loosens, making your pouch bigger and allowing more food intake, which is why you have to get a fill.
When you have reached your goal weight, as long as you maintain within 5 lbs, they let your band become bigger so you can eat "normally" again. You still have eat healthy and learn your portion control.
However, this band is only a tool to help you achieve your success. You, yourself have to realize that this band is not an easy way out. It is a life style change in your eating habbitts.
I am 20 years old and just had lap band 1 week and 4 days ago. It's a tough process, but very worth it!!!!!
