Newly diagnosed question

Hi I was just diagnosed with colitis after my colonoscopy. I have no symptoms, but my Dr wants me to go in and talk about getting on medication. Do I really have to be on medication if I have no symptoms? I really do not want to take more meds if I don't have to, I already take meds, for blood pressure, cholesterol and thyroid I really don't want to add more. What is the point of the medication is it for symptoms? What is the negative on not going on medication?

Thanks

Your doctor is absolutely correct. First line of medications have very few side effects. The disease is tricky. Flares become harder to treat and control. This is a serious and possible life changing diagnosis so getting ahead of the disease now could save you pain, agony in the future. I regret not taking it as serious as I should have when I was first diagnosed.
Good luck
