People with insulin-dependant diabetes will be banned from driving taxis in Newcastle-under-Lyme, Staffs, if the borough council approves plans.
Authorities in Stoke-on-Trent and Stafford already stop drivers with the condition from taking on such work.
The private hire association in Stoke claims insulin-dependant diabetics have been going "in droves" to Newcastle.
The plans, which follow a Driver and Vehicle Licensing Agency directive, will be discussed on Monday.
A meeting of the public protection committee will assess the proposals.
Drivers are currently approved in Newcastle on the recommendation of their GPs.
