No published record matching the claim that approximately one in three people in the UK avoid discussing bowel symptoms with their doctor due to embarrassment was located; this does not prove the claim false. While embarrassment is widely documented as a substantial barrier to medical help-seeking for gastrointestinal and colorectal symptoms in qualitative and survey literature, peer-reviewed epidemiological data quantifying this exact one-in-three proportion were not identified, suggesting the figure likely derives from unindexed charity or public opinion polling reports.
