Hi there ~ Weight loss surgeries like gastric bypass are very effective in losing weight if you are someone who is able to tolerate the same. However you need to have extensive testing done to have the surgery and you need to see a bypass surgeon to make sure you are having a good health to undergo the surgery. I am not sure about the eximia technology or the slimming pills or their effects or side effects, and there I suggest that you see a doctor to get things cleared up. I hope this helped. Take care and have a lovely day!
