Diabetes in the elderly: diagnosis, pathogenesis, and therapy

Area of Science:

• Gerontology
• Endocrinology
• Metabolic Diseases

Background:

• Diabetes mellitus prevalence significantly increases with age, affecting 10% of those 60+ and 16-20% of those 80+.
• An additional 20% of elderly individuals exhibit age-associated hyperglycemia, potentially representing a spectrum leading to Type II diabetes.
• Approximately 40% of the senior population has abnormal carbohydrate tolerance, increasing risk for chronic diabetic complications.

Purpose of the Study:

• To highlight the prevalence of diabetes and hyperglycemia in the elderly population.
• To discuss the multifactorial basis of these conditions, involving insulin secretion and action.
• To outline challenges and a rational approach for managing glucose homeostasis in older diabetic patients.

Main Methods:

• Review of epidemiological data on diabetes and hyperglycemia prevalence in aging populations.
• Analysis of physiological and pathological changes associated with aging and their impact on glucose metabolism.
• Consideration of factors complicating treatment in elderly patients, including comorbidities and polypharmacy.

Main Results:

• High prevalence of diabetes mellitus and age-associated hyperglycemia in individuals aged 60 and above.
• Identification of multifactorial causes for abnormal carbohydrate tolerance in the elderly.
• Recognition of unique challenges in treating diabetes in older adults due to physiological changes and comorbidities.

Conclusions:

• A significant portion of the elderly population faces risks associated with abnormal carbohydrate metabolism.
• Effective diabetes management in seniors necessitates a comprehensive approach addressing age-specific factors.
• A rational strategy for glucose homeostasis maintenance is crucial for older patients with diabetes.
