Why Is My Blood Sugar High Even When I Don't Eat Sweets?
Table sugar is not the only thing that affects glucose. Starches, portions, illness, stress and medication all matter.
Avoiding sweets does not guarantee that blood sugar will stay in range. Many foods that are not sweet—such as rice, roti, potatoes and other starches—contain carbohydrate that is broken down into glucose.
Common reasons glucose can rise
- A larger amount of carbohydrate than your body or treatment plan can handle at that time.
- Large portions of starches, even when no table sugar is added.
- Illness or infection.
- Stress.
- Not enough insulin or another problem with the medication plan.
““No sugar added” and “no effect on blood sugar” are not the same thing.”
What to do instead of guessing
Record meals, medication as prescribed, activity and readings. Repeated patterns can help you and your healthcare professional identify what needs attention. Do not repeatedly skip meals or change prescribed doses just to force a number down.
Frequently asked questions
Can rice raise blood sugar even though it is not sweet?
