The Duchess of Cornwall has officially named a new hospital clinic as part of a day-long tour of Cornwall.
Camilla met patients and staff and toured the newly christened Duchess of Cornwall Centre for Osteoporosis at the Royal Cornwall Hospital in Truro.
During the visit she urged young people to follow a healthy lifestyle to help prevent bone and joint disease.
She also visited the disaster relief charity Shelterbox in Helston and animal charity Cinnamon Trust in Hayle.
The duchess last visited the county in May together with Prince Charles.
Her visit to the hospital on Thursday was delayed by an hour after low cloud forced her helicopter to divert to Mawgan Airport near Newquay.
Camilla is president of the National Osteoporosis Society. Both her mother and grandmother died as a result of the disease.
She said: "It is important to raise awareness of the joint problems of both osteoporosis and arthritis to help prevent these painful, debilitating and sometimes fatal conditions.
"It is vital young people learn regular exercise and a healthy diet is important to their bone health in future."
Professor Anthony Woolf, who provides the clinical services for osteoporosis at the hospital, said the duchess was "keen to see how we are progressing and happy to support us by lending her name to the centre".
