Common Causes of Highs

Carbs break down into sugar, and that sugar enters your blood after you eat. Think of your blood as a sink. A bigger carb portion is like turning the tap higher.

Bread, rice, pasta and fruit all raise blood sugar in larger portions, not just sweets. A large bowl of plain rice can push a reading up, even with no dessert.

Illness, stress and poor sleep add extra load to your body. Think of it like carrying a heavy bag up the stairs.

Illness can push blood sugar up even when your meals stay the same. Poor sleep and stress can push readings higher too.

A single reading shows one moment. A pattern across many days tells you more, like a weather log. One rainy day says little, but a month shows the season.

Keep notes of meals, sleep, illness and missed doses. If you miss a dose, call your care team for advice.

Key takeaways

• Large carb portions, even of plain foods, can raise blood sugar.
• Illness, stress, poor sleep and missed medicine can all push readings up.
• A pattern across many days helps your team more than any single reading does.

Try it

Today, write down your meals, how you slept and any stress or illness, then look at the note tomorrow.
