What People Say About Dr. Gilbert Ong, MD
RecentHighestLowestMost Helpful
Initial visit was great with Dr. Ong. He seemed very kind, professional and caring. A few weeks later, I was extremely ill with a lot of pain and unable to eat for almost 2 weeks at this point, I called his office and his nurse first of all needs to practice some empathy, secondly he just prescribes me pain pills for IBS and waits another week for an exam. By the time i see him i have lost 10lbs and have not been able to eat, he insists its IBS and tells me to go home with no other management or care plan until my colonoscopy. My procedure shows nothing major, again communicated over a week later by a LETTER, and his office JUST tried to set up a follow up appointment when i told him multiple times and my dad at pick up told him i still cannot eat and am having bowel issues. IT is now been 2 months. So regardless if its IBS or not, a patient's care and management of pain and lifestyle should be top of mind as a doctor. Instead of sending me home with no plan, no care.
