Yea I think it means a sigmoidoscopy. In french they just write it as "short colonoscopy"
Unfortunately I don't have the privilege to ask my doctor for what to do. I'm 23 years old, so they most likely don't judge it necessary to have a full check. They also usually don't allow you to question them around here. And nope, no calcium, though I do enjoy some cheese here and then. But It's not as if I eat some all the time.
Plus, I been waiting so long for the sig, imagine how long I would've waited for a full. I should be glad they decide to shove anything there at all.
