Type 2 Diabetes: The Basics

Diabetes & Endocrine • Medically reviewed November 2023by the Cedarcrest Health clinical content committee

Type 2 diabetes is a condition in which the body has trouble using insulin properly, causing blood sugar (glucose) levels to rise above a healthy range. It is the most common form of diabetes and often develops gradually, sometimes over many years, before it is diagnosed.

Why Blood Sugar Control Matters

Glucose is the body’s main source of energy, and insulin is the hormone that helps move glucose from the bloodstream into cells. When cells become resistant to insulin, or the pancreas cannot keep up with demand, sugar builds up in the blood. Over time, this can damage nerves, blood vessels, eyes, and kidneys.

Risk factors for type 2 diabetes include being overweight, having a family history of the condition, carrying extra weight around the waist, and being less physically active. Age also plays a role, though the condition is increasingly diagnosed in younger adults as well.

Managing Day to Day

• Eat regular, balanced meals with attention to portion sizes.
• Stay physically active, which helps your body use insulin more effectively.
• Monitor your blood sugar as recommended by your care team.
• Keep up with recommended eye, foot, and kidney checks.
• Attend regular visits so your care plan can be adjusted as needed.

Many people with type 2 diabetes lead full, active lives by working closely with their care team and making steady lifestyle adjustments. Small, consistent changes in eating habits and activity often make a bigger difference than dramatic short-term efforts.
