Hi Welcome to Health care magic forum. A fasting blood glucose
level according to the site you have seen represent the pre diabetic range, and it could be an error also as it is a minor increase. So it is not a major health problem, it is to be estimated again to evaluate the condition with out loading with sweets prior night.
If it is at this level also not much of importance, and P.P glucose level is to be found on that it decided. if that is normal, and fasting level is 105only diet controle and exercise will do to combate the rise.
If you want a clear idea about this you can consult an endocrinologist
for confermation or exclsion of the disease.
Besides i advise you some diet recommendations as controle the intake of sweets, potato and other tubers, and flushy fruits like banana, guva, etc.
Wishing for a clean chit about diabetis and thanks for calling.
