Suggest Treatment For Gallstones Which Show No Symptoms

Hi I have just been diagnosed with gall stones. I have some small ones and one is 14mm. I have no symptoms and am healthy. I am a 44 year old female. My doctor says I must have my gall bladder removed. I don t want to as I have no symptoms and feel fine. He says if I don t I will get a blockage in the future, will be extremely I ll, and will have to have it out anyway. He says it will have to come out at some point whether now or in the future. I feel scared now but as I say feel physically fine. Any suggestions what to do? Thanks
