I'm 19 years old and i had 4. i also have a lot of the same issues as you do, i would go right back to the doctor and ask for one.
Yes. Have your doctor refer you to a Gastroenterologist (GI DOC) to have a colonoscopy. Because of your genetic makeup, you should especially get a screening because your chances of developing an intestinal/colon condition is higher for you. You may have a mild form of IBD, but that can be treated with medications and diet changes. Good luck to you
I agree with FurballsMom. Request a colonoscopy.
With that kind of family history, you should certainly get a colonoscopy. I think it's reasonable if there is a family history and/or you have symptoms to warrant such a test. Your insurance has to cover it when getting tested is the reasonable thing to do.
