Has there been any side affects from Byp Slim Ball?

I am thinking of using this product but I am 55 and over 100 lbs overweight . I work in public & I don't want eruptions of gas. Anyone who knows about this product please respond. This decision scares me a bit. Is it healthy or not?This product is a pill swallowed that is pure fiber and expands up to 50% it will cause the stomach to feel full making you eat less without the byp surgery.. The product claims very fast weight loss The claims sound great but I have doubts.
