Thank you for your query at AskTheDoctor.com
I understand your concern.
A FBS of 164 definitely warrants further investigation with at least a repeat FBS/PPBS along with a HBA1c count.
HBA1c count will help us understand the average blood glucose levels over the past three months, and reject any possibility of sporadic rise in Blood Sugar.
Also, get your BP levels checked.
Feel free to discuss further.
