Residents in Broughty Ferry are struggling to register with a local GP, a councillor has warned.
Liberal Democrat representative Craig Duncan has written to interim NHS Tayside chief executive Malcolm Wright asking for answers.
He is concerned people in the Ferry are consistently unable to sign up with their local doctor, an issue Mr Duncan said would affect elderly and vulnerable people most.
The councillor noted issues with travelling greater distances could prove a problem for those less mobile and said it was time the list sizes were rebalanced in favour of local service users.
NHS Tayside said it was the responsibility of the health centre or GP surgery to determine their own catchment area. Broughty Ferry has two health centres – Broughty Ferry and Grove.
Figures show Broughty Ferry has a list of 8,953 patients and Grove has 6,106. The average list size in Dundee is 6,488.
