For those not in the UK to explain, NHS means the National Health Service. GPs work for the NHS. Angharad is a health visitor who works alongside GPs for the NHS and they usually work out of the same practices with the same computer systems and medical notes and same patients.
I know there is supposed to be confidentiality when you see your GP but I can understand her fears.
Lets hope she can find a way around this so she can get medical advice without jeopardising her job and career.
