The fasting blood sugar of 7.8 is a bit high, because the normal blood sugar level is 3.9~6.1.

So the blood sugar is a bit high, but it is not very high and has little impact.

Pay more attention to your daily diet and lifestyle, and use general dietary therapy to lower blood sugar.

Do the following:

1. Eat more foods rich in potassium and calcium but low in sodium, such as potatoes, eggplants, kelp, and lettuce.

2. Eat foods that help lower blood sugar, such as oats, wheat, buckwheat and other foods.

3. Keep your mouth shut and don’t eat foods high in sugar.
