Just going back to the original post, I personally love this programme, in fact I love all things medical. Plus it's how I learn not just for me but one day I may be able to help anther person.
I think really the name is wrong now as it I no longer just people with an embarrassing problem. Many many have been through the NHS mill for years and got nowhere but this programme gets results in return for a person agreeing to appear.
I remember well the case of a child with masses of varrucas who docs had given up on, the doc on the show diagnosed a rare disorder and she needed chemotherapy to save her. Left to the NHS she was likely to have died.
