My Parents Have Diabetes. Am I Next? Understanding Type 2 Diabetes Risk and Prevention

If one of your parents has type 2 diabetes, you may have wondered: “Will I get diabetes too?”

Having a parent or sibling with type 2 diabetes increases your risk but it does not mean diabetes is inevitable.

Type 2 diabetes is influenced by multiple factors, including genetics, age, body weight and composition, physical activity, lifestyle, and metabolic health. You cannot change your family history. But there are risk factors you may still be able to change.

Is Type 2 Diabetes Hereditary? Type 2 diabetes has a genetic component, and having a first-degree relative with diabetes is an important risk factor. But increased risk does not mean certainty.

The American Diabetes Association (ADA) considers family history alongside other factors such as body weight, physical activity, blood pressure, and conditions associated with insulin resistance when assessing the need for diabetes screening.

So instead of asking only: “Did I inherit diabetes?”

Consider asking: “Where does my diabetes risk stand today?”

Prediabetes Can Develop Before You Notice It

You can feel perfectly healthy while your metabolic health is beginning to change. Prediabetes occurs when blood glucose is higher than normal but has not yet reached the diabetes range and it can develop without obvious symptoms. You may still be working, traveling, and exercising normally without realizing that your glucose regulation has changed. This is why waiting for symptoms may mean waiting too long to start paying attention.

Not Overweight? You May Still Be at Risk

Body weight is only one part of diabetes risk.

Doctors may also consider abdominal fat, physical activity, blood pressure, lipid levels, age, PCOS, previous gestational diabetes, family history, and other factors associated with insulin resistance.

This is particularly relevant for people of Asian ancestry. The ADA uses a BMI threshold of ≥23 kg/m² for individuals of Asian ancestry when considering risk-based screening in adults with additional risk factors. So “I'm not overweight” does not necessarily mean “I'm not at risk.”

When Should You Get Tested for Diabetes? Diabetes screening is not only for people who already have symptoms. The ADA recommends screening from age 35 for adults who do not already meet criteria for earlier risk-based testing. Earlier testing may be appropriate when additional risk factors are present.

Common tests include:

• Fasting Plasma Glucose (FPG): measures blood glucose after fasting.
• HbA1c: reflects average blood glucose over approximately 2–3 months.
• Oral Glucose Tolerance Test (OGTT): assesses the body's response to a glucose load.

The appropriate assessment depends on the individual. Preventive medicine isn't about doing the most tests. It's about knowing what to test, for whom, and when.

Can Type 2 Diabetes Be Prevented If It Runs in Your Family?

You cannot change your genetics, but some risk factors are modifiable. For people with prediabetes or increased risk, appropriate nutrition, regular physical activity, and weight management when relevant can help reduce the risk or delay the development of type 2 diabetes. This does not guarantee prevention. But understanding your risk earlier may give you more time to act on the factors you can still change.

Don't Wait for a Diagnosis to Start Paying Attention

If diabetes runs in your family, prevention can start with understanding where you are today.

At R3 Life Wellness, a physician may recommend appropriate laboratory testing, such as blood glucose, HbA1c, lipid profile, and other relevant markers, while considering your family history, blood pressure, body composition, lifestyle, and overall metabolic health together.

The goal is not simply to label a result “normal” or “abnormal.” It is to answer a more useful question:

“What can I still change?” If results suggest increased metabolic risk, your physician can help identify appropriate next stepsfr om nutrition, physical activity, and weight management to follow-up testing and ongoing metabolic health monitoring.

This World Diabetes Day, 14 November, if type 2 diabetes runs in your family, don't wait for a diagnosis to become the reason you start paying attention.

Know your numbers. Understand your risk. Start with what you can change.

Family history is a risk factor. It is not your destiny.

FAQ

If my parents have type 2 diabetes, will I get it too?

Not necessarily. Family history increases your risk, but it is only one factor. Lifestyle, age, body composition, blood pressure, and overall metabolic health also matter.

Can I have prediabetes without symptoms?

Yes. Prediabetes can occur without obvious symptoms, which is why screening may be important if you have risk factors.

If my results are normal, do I still need to monitor my diabetes risk?

A normal result reflects your health at that point in time. If you have a family history or other risk factors, your physician can advise when to reassess and which modifiable factors may be worth addressing.
