The poll of 400 doctors found that 48% of GPs said they were stressed and significantly overworked every day, compared with around a third of medical professionals overall.
Three out of 10 doctors responding to the poll said the stress they were under had affected how they deal with patients, according to the British Health Report, commissioned by a legal services firm.
The findings echo the results of the BMA's largest-ever poll of GPs, which found that one in three GPs planned to retire within five years amid soaring workload pressure that nine out of 10 GPs believe is undermining patient care.
Reacting to a finding from the BMA poll that 16% of GPs report 'significant and unmanageable stress', GPC deputy chairman warned that soaring GP stress was 'an alarm bell that should be ringing across the country'
RCGP chairwoman Dr Maureen Baker has warned that heavy workload and stress among the profession is a 'genuine danger to patient safety' as well as to the 'wellbeing of hardworking family doctors and our teams'.
The latest poll was commissioned to coincide with the start of depression awareness week.
