More New Zealanders are using the internet to research their medical woes - and some are using their findings to treat themselves rather than visit a doctor.
TNS research for the Southern Cross Healthcare Group, showed 55 per cent of Kiwis used the internet to research their ailments, and 22 per cent said they did so at least once a week.
The survey of about 2000 people, completed in September and released this week, showed 22 per cent of those questioned went on the internet to identify the issue themselves.
It also showed that 9 per cent of respondents would take their findings to their GP but 7 per cent would diagnose their problems on the internet and not seek any medical help or advice.
The head of the general practice department at Otago University, Christchurch, Professor Les Toop, said self-diagnosis was not new as people had previously gone to libraries to look up their issues.
He said on-line diagnoses could be helpful, but he cautioned against over-reliance on the internet.
"It is a completely unregulated environment ... some of the information is good, some of it's not and some of it is driven by advertising and sales."
He said he didn't have a problem with websites that offered solutions for people with minor irritations.
"Where it would be [a problem] is where people are trying to diagnose themselves for having haemorrhoids when they have got bowel cancer."
Medical Association chairman Mark Peterson said self-diagnoses on the internet were among the biggest Google search categories, and were sometimes helpful in arming patients with more information when they went to visit their GP.
Southern Cross Healthcare Group chief executive Ian McPherson, a former GP, said it was was not surprising people were turning to the internet given the wealth of information available online.
The national TNS survey showed those most likely to search for health information online were people living in Wellington and Tauranga, females and those under 50.
