Subtle signs that signal diabetes risk in older adults

Type 2 diabetes affects a growing proportion of seniors in Romania, and endocrinology specialists are warning about the importance of early detection of prediabetes — the stage that precedes the full development of the disease.

The subtle signs of prediabetes

Prediabetes often presents through mild symptoms that many older adults may dismiss as normal for their age: chronic fatigue, persistent thirst, frequent urination, and slow healing of minor wounds. These symptoms appear when blood glucose levels fall between normal values and those considered diabetic.

From a medical standpoint, prediabetes is diagnosed when fasting blood glucose falls between 100–125 mg/dl, compared to the normal threshold of under 100 mg/dl. Additionally, a glucose tolerance test may indicate values between 140–199 mg/dl two hours after glucose administration.

Specific risks for older adults

In people over 65, prediabetes can progress more rapidly towards full type 2 diabetes, given the metabolic changes specific to the ageing process. Loss of muscle mass and reduced physical activity contribute to insulin resistance, facilitating the progression of the disease.

A diet rich in processed foods and hidden sugars — increasingly common in modern eating habits — accelerates the development of metabolic imbalances. Seniors are particularly vulnerable, given that their metabolism processes excess glucose more slowly.

Prevention and management

Specialists recommend regular blood glucose checks for all people over 45, and for those with risk factors — obesity, family history, or a sedentary lifestyle — monitoring should begin earlier. Lifestyle changes can reverse prediabetes in up to 70% of cases.

For older adults, adopting a balanced diet, engaging in adapted physical activity, and losing as little as 5–10% of body weight can prevent or delay the onset of type 2 diabetes. Regular consultation with a GP and an endocrinologist remains essential for monitoring progress and adjusting the treatment strategy.
