If I have hyperglycemia & HbA1c (type 2 diabetes) can I make desserts with canderel or other artificial sweetener Thanks?

Diabetes. Yes, you can make desserts with those artificial sweeteners. The key thing with diabetes is to avoid overindulgence. You can negate the benefits of using such sweeteners if you eat too much of them. Make sure to keep your portion sizes down and pay back any excess via regular cardiovascular exercises, like walking, swimming, zumba etc., or what ever exercise you enjoy.
