Protestors gathered outside the gates of Waterford Regional Hospital this morning.
The peaceful protest was being held in frustration at long waiting lists at the hospital.
The father of an 11-year-old girl, who was among the protestors, says his daughter has already been waiting two-and-a-half years to get her tonsils removed.
The girl is currently in hospital receiving treatment for severe tonsillitis, which could be relieved if her tonsils were removed.
She has asked Health Minister Mary Harney to come to her bedside and explain to her why she must wait another possible two to three years to have her operation.
