If diabetes runs in your family, such that both of your parents have it, it is time to re-examine your habits, diet, and physical fitness, and go for a lifestyle overhaul. Why?
If both parents have diabetes, especially type 2 diabetes, the chances of developing it increase significantly due to both genetic and environmental factors, experts emphasise. “If your parents have type 2 diabetes, your risk of developing the condition increases significantly. Genetics play a major role, and studies show that having two diabetic parents can raise your lifetime risk to over 50 per cent,” said Dr Rajiv Kovil, head of diabetology, Zandra Healthcare and co-founder of Rang De Neela Initiative.
This familial link means you may inherit insulin resistance or beta-cell dysfunction, which affects how the body regulates blood sugar. “Over time, these changes can lead to elevated fasting blood glucose levels or poor glucose tolerance, even if asymptomatic in younger years,” added Dr Hiran S Reddy, consultant physician, diabetologist and critical care specialist, Gleneagles Hospital, Lakdi ka Pul, Hyderabad.
It’s important to note that while the genetic risk is real, diabetes is not inevitable. If parents were diagnosed at an early age, the inheritance is faster and premature, Dr Kovil noted. However, genes are only part of the story—lifestyle plays a critical role in whether or not diabetes actually develops. “We always say hereditary loads the gun, lifestyle pulls the trigger,” said Dr Kovil.
The good news is that type 2 diabetes is largely preventable. “Maintaining a healthy weight is key; even a 5–7 per cent reduction in body weight can dramatically cut your risk. Focus on eating a balanced diet rich in vegetables, whole grains, lean protein, and healthy fats. Avoid sugary beverages and highly processed foods,” Dr Kovil said.
If you’re overweight or have prediabetes, regular check-ups and early medical guidance can help delay or prevent progression.
Regular screening, especially if over 25 or have other risk factors like obesity or a sedentary lifestyle, is crucial for early detection. “Monitoring fasting blood sugar, HbA1c levels, and lifestyle patterns can provide early warning signs,” said Dr Reddy.

To lower risk, adopt healthy habits early.
“A balanced diet rich in fibre and low in refined carbs, consistent physical activity, maintaining a healthy weight, and avoiding smoking or excessive alcohol can all help prevent or delay the onset of diabetes. With the right steps, one can protect long-term health,” said Dr Reddy.
While you can’t change your family history, you can change your future, asserted Dr Kovil. “With conscious effort and regular monitoring, type 2 diabetes doesn’t have to be your destiny,” said Dr Kovil.
