Understanding Your Blood Sugar

Why High Blood Sugar Is a Modifiable Risk Factor

High blood sugar, also called hyperglycemia, happens when your body has trouble using sugar for energy. Over time, too much sugar in your blood can damage small blood vessels in your eyes, kidneys, nerves, and brain.

  • You Can’t Feel High Blood Sugar: High blood sugar usually does not cause symptoms at first. Many people feel fine, even when their levels are too high. The only way to know for sure is through a blood test done at a lab or doctor’s office.
  • High Blood Sugar Impacts Other Health Conditions: High blood sugar impacts other conditions too, including high blood pressure and high cholesterol. These conditions are closely connected and often occur together, so it’s important to get your blood sugar checked.

You Have Control

The good news is that you can take steps to control your blood sugar. Regular exercise, healthy eating, and good sleep habits all help your body use sugar more effectively.

You can start small by doing some jumping jacks or squats in your own home. There are also at-home workout videos online for 5-10 minutes, if you do not have a lot of time. For healthy eating, you can start with a small step by swapping out one of your meals with red meat, for a lean protein option (e.g., chicken, turkey). Or, if you drink a soda every day, you can start by going one less day without a soda.

Every small action matters. Taking a 10–15 minute walk after meals helps your body use the sugar from food right away and can lower blood sugar levels.

Partnering With Your Doctor

When you see a doctor, they may also check your weight, blood sugar, blood pressure, and cholesterol. These are all related health conditions. Looking at your whole health picture helps your doctor create a treatment plan that fits your needs.

  • Exploring Medication Options: Many people think insulin is the only treatment for high blood sugar. While insulin can be helpful, there are now several newer, non-insulin medications that work very well for many people.
  • Open Communication Is Key: If you start medication, tell your doctor right away if you notice side effects. Some side effects may improve after a few weeks, but your doctor can adjust your treatment if needed.

Getting your blood sugar under control is an important step toward lowering your risk of brain disease.
