    Dr Cheng notes on my visits rarely match what we talk about in office- the way she notes make it sound like im doing well. Im not sure how having 15- 20 BMs a day is doing well. My quality of life if low due to my constant BMs. I have shared with her for years that adding fiber or using diarrhea meds only makes matter worse - she never remembers this

    I was informed that I would get a Mychart message about feedback and topics discussed. I have not received that expected feedback.

    I started meeting yearly with Dr Cheng, once my previous gastroenterologist retired. She has been a joy in taking care of me and I feel like I'm in great hands. She asks lots of questions to reaffirm how my ulcerated colitis is going and affecting my life. Dr Cheng is great!

    Appointment with doctor really consisted of Q&A. Thought it would have been more convenient to have answered all questions online instead of going to office appointment.
