Single large gall stone acceptable for Class1
Hello GSXR1K,
I´m a radiologist in Switzerland. 7 mm is not a big gallstone. Anyway, I would reccommend to wait and see, because we usually find a lot of gallstone when doing ultrasound. When it becomes symptomatic, in 1-80 years, even mild, for instance, getting pain after eating fatty things (like Swss chees fondue...) it´s time to call for the surgeon.
hope that helps
