Brief Answer:
You can often control your blood sugar with diet

Detailed Answer:
Hello,
A fasting blood sugar of 125 is considered elevated and a risk factor for diabetes, and it is possible that you do have diabetes, and so I would recommend getting your hemoglobin A1c checked, which gives an average of your blood sugar over the last 3 months and is a more accurate way of determining if you have diabetes. Otherwise, there are ways that you can lower your blood sugar with diet, there are many ways to approach it, but for example you can read about the diet you should have here: https://www.diabetes.org.uk/guide-to-diabetes/enjoy-food/eating-with-diabetes/what-is-a-healthy-balanced-diet. If you are overweight at all, losing weight can also have a significant impact on your blood sugar. Finally, exercise is another way you can improve your blood sugar, for example, by performing 30-60 minutes of moderate-intensity aerobic activity, such as walking or cycling.

I hope that helps, please let me know if you have any other questions about that, and I would be glad to discuss it with you further.
Thanks.
