Diabetes complications and how to prevent them

IRIS Prévention
16 December 2026
The real danger of diabetes is not sugar itself, but the complications of prolonged hyperglycemia. The good news: they warn each other.

Diabetes is especially worrying because of its long-term complications. Persistently high blood sugar slowly damages blood vessels and nerves, which can affect the eyes, kidneys, heart and feet. But these attacks are not inevitable: good control and regular monitoring can largely prevent them.

1. How excess sugar damages the body

Chronic hyperglycemia damages the walls of small and large vessels, as well as the nerves. These lesions develop silently over years, which makes regular monitoring essential before symptoms appear.

2. The main complications

OrganPossible complication
EyesRetinopathy (damage to the retina)
LoinsNephropathy (kidney damage)
NervesNeuropathy (loss of sensitivity)
Heart and vesselsInfarction, stroke, arteritis
FeetWounds, risk of ulcers

These complications are all the more limited if the diabetes is well controlled and detected early.

3. Monitoring that protects

Regular monitoring makes it possible to detect these conditions before they worsen: eye examination, renal assessment, foot monitoring, cardiovascular monitoring. These checks are part of diabetes management.

4. Prevention levers

Balancing your blood sugar, controlling your blood pressure and cholesterol, not smoking, moving and eating well greatly reduce the risk of complications. Every improvement counts, no matter how small.

The message is optimistic: well-monitored diabetes allows you to live a long and healthy life. The prevention of complications is largely in our hands, with the support of the healthcare team.
