My polygenic risk score for type 2 diabetes is in the 95th percentile. Do I need to panic?

No, but pay attention.

A 95th percentile polygenic risk score for type 2 diabetes does not mean a 95% chance of getting diabetes. It means that out of the population the score was calibrated on, your genetic risk is higher than 95% of people. The translation to absolute lifetime risk depends on the population, the model, and your other risk factors.

For type 2 diabetes specifically, the 95th percentile usually translates to roughly 2 to 3 times the average lifetime risk. If the average risk in your demographic is, say, 25%, your genetic baseline is around 50–60%. That is high, but it is not destiny.

What changes the picture significantly - and this is the part that matters most - is lifestyle. Type 2 diabetes risk responds strongly to body composition, dietary patterns (particularly refined carbohydrate intake), physical activity, and sleep quality. Multiple large studies have shown that lifestyle modification can roughly halve the risk even in people with high genetic susceptibility.

What I'd recommend, in order:

- Get baseline labs: HbA1c, fasting insulin, lipid panel, ApoB if available.

- If you are South Asian: get these earlier than the general recommended age. T2D presents earlier and at lower BMI in our population.

- Don't make major dietary changes based on the genetic score alone; make them based on the labs.

- Re-test every 6–12 months for a few years to see where you actually trend.

The score tells you which dial to pay attention to. The labs tell you whether the dial is moving.
