“Risk Factors for Developing Prediabetes – Including Family History”

What is prediabetes?

Prediabetes means your blood sugar is above normal but not yet diabetic. It shows your body is struggling with insulin and sugar, and if ignored, can lead to type 2 diabetes over time.

The good news: lifestyle changes at this stage can often lower sugar and prevent diabetes.

Major risk factors

1. Family history of diabetes

If a parent or sibling has type 2 diabetes, your prediabetes risk increases by about 26–40%, even after adjusting for weight and age.

2. Obesity and belly fat

Extra weight, especially around the waist, strongly links to insulin resistance. A BMI above 25 or high waist circumference is one of the clearest risk factors.

3. Age and inactivity

Risk rises after age 35–45, and sitting too much without exercise significantly raises chances of prediabetes.

4. Poor diet and health conditions

• High sugar, refined carbs, processed foods, and sugary drinks increase risk.

• Gestational diabetes, PCOS, sleep apnea, high blood pressure, and smoking also raise it.

Why family history matters

Family history signals both genetic risk and shared habits (food, movement, lifestyle).

If diabetes runs in your family, your body may be more prone to insulin resistance even at a normal weight, so early testing and stricter habits are important.

Simple ways to lower your risk

• Aim for 5–10% weight loss if you’re overweight.

• Walk or move at least 150 minutes per week and reduce long sitting hours.

• Choose more vegetables, whole grains, dal, pulses, nuts, and healthy fats; cut sugar and refined carbs.

• Get blood sugar tested early if you’re over 35–40 or have a family history of diabetes.
