Jointly hosted by the Diabetes Association of Thailand under the Patronage of HRH Princess Maha Chakri Sirindhorn, the event saw many NLA members and government officials undertake health checks.
Association president Wannee Nitiyanant said at least four million Thais, or 8 per cent of the population aged over 15, suffered from diabetes.
Wannee said up to eight million Thais risked developing type two diabetes due to their overeating and inactive lifestyles.
