Researchers at the University of Utah Health have conducted a survey suggesting that a large proportion of people have a tendency to lie to their doctors about information that could be relevant to their health.
Up to 80% of the participants admitted to not having been forthcoming about lifestyle factors such as exercise and diet. The study also found it was common for respondents to not speak up when they disagreed with the recommendations their doctor made and for them to fail to admit they had not understood the instructions.
