I had the fumdo done in oct of 2000 and had to go back and have it done again in April 2001 because it did not stay in tack. You cannot throw up or belch for about 4 weeks just because it can come apart. I am verey happy with the results. I have been heartburn free after sufferinf for about 10 years. You do lose some weight also. So what it comes down to is do it and you will be happy.
