Early Action on Diabetes for Young Adults: Why Now Matters

November is Diabetes Awareness Month, and one group often overlooked is young adults.

When people picture diabetes, they often think of someone older - that picture is outdated. Type 2 diabetes was once called "adult-onset," but that label has faded as diagnoses climb among teens and young adults.

The numbers are a wake-up call

• Roughly 6 million U.S. adults aged 18 to 44 have diabetes, and about 2 million of them don't know it.
• Nearly 33 million adults in that age range have prediabetes.
• According to the Centers for Disease Control and Prevention, about 1 in 4 young adults (ages 19–34) and nearly 1 in 5 teens (ages 12–18) are living with prediabetes.
• Rates are higher among Hispanic, Black, Asian, American Indian, and Alaska Native communities.

Why it hits younger people harder

Diabetes that starts early is not milder. It tends to be more aggressive. Early-onset type 2 diabetes leads to complications sooner than diabetes diagnosed later in life. National Institutes of Health (NIH)-funded research on people diagnosed as teens identified serious kidney, heart, eye, nerve, and pregnancy complications emerging in early adulthood, at a pace at least as fast as in people diagnosed later. Someone diagnosed at 25 has decades more exposure to high blood sugar, and the damage adds up.

What it does to the body

Over time, high blood sugar can harm nearly every system:

• Heart and blood vessels: higher risk of heart disease and stroke
• Kidneys: chronic kidney disease, which can progress to failure
• Eyes: vision loss and blindness
• Nerves and feet: numbness, pain, and in severe cases amputation
• Pregnancy: greater risks for both parent and baby

Young adults with prediabetes already show higher cholesterol, higher blood pressure, more abdominal fat, and lower insulin sensitivity. The strain on the body starts before a diagnosis.

The good news: early action works

Complications are not inevitable. The CDC notes that good blood sugar management can cut the risk of eye, kidney, and nerve disease by about 40%. Regular eye exams could prevent up to 90% of diabetes-related blindness, and routine foot exams and education could prevent up to 85% of amputations.

What you can do this month

• Know your risk. Ask your doctor about an A1C or fasting glucose test, especially with a family history, excess weight, or inactivity.
• Move more. Even a daily 30-minute walk improves insulin sensitivity.
• Eat with intention. Choose whole foods, fewer sugary drinks, and balanced portions.
• Sleep and stress matter. Poor sleep and chronic stress both affect blood sugar.
• Join a prevention program. The CDC-led National Diabetes Prevention Program has a strong track record for young adults.

You don't need to wait for symptoms. A simple test today could change your health for decades.
