Two people were diagnosed with a condition they never knew they had during a health awareness day held in Swaffham at the weekend.
Medical teams who led the testing at the Assembly Rooms on Saturday were pleased that most were not in danger of more severe health problems.
But they admit that more needs to be done in order to reach more of the people who are most at risk.
Organisers estimate that around 100 people took advantage of the session, which offered screening for diabetes and cardiac health issues.
Among those examined were two patients confirmed to have diabetes, who were previously unaware they had the condition.
Six other people were told they needed further medical tests.
The session was organised by the Swaffham Lions, in conjunction with the Norfolk Community Health and Care NHS Trust, whose medics provided the tests.
And Julie Widdowson, lead diabetes practitioner for the trust, said: “There are more people out there we need to reach who are at risk.
“Today, the majority of clients were below the at risk level which was good.”
The event was the third of its kind to have been hosted by the Lions in a bid to help raise peoples’ awareness of the risks of diabetes and other health issues.
