    Due to my symptoms, perhaps order blood work to rule out a bacterial infection?

    She did not show genuine concern. She did not listen to my concerns.treated me like a transaction. Based all findings off of act scan instead of here current and persistent issues of health. Did not tell me any thing different than my primary care physician. Defended previous gastric doctors practice without showing concern about the experience I had . Needs better bed side manner.

    I like that she is exploring my condition. But she is not in the office regularly and they only have one gastrologist in the office. So if I need something urgent, I am out of luck.
