Dr. Francis Faustino is chief of family practice at Winthrop University Hospital, he says you and your doctor should be a team.
"It takes time and it's a physician patient relationship that needs to be developed so that your patient will tell you the truth," he said.

Some people downplay symptoms out of fear of a diagnosis.
Others create symptoms to get a certain test or antibiotics.
And the biggest reason patients lie is because they don't want to disappoint their doctor
But it's not worth it, to disappoint your doctor.
If you're not really taking your medication, fess up or your doctor may raise the dose to a level you don't need.
If you're taking supplements, say so, they may interact with prescription medication.
And if you feel like you can't tell the truth because your doctor is judging you, it's time for a new doctor.
