Diabetes and Aging - Confronting Geriatric Syndromes in Older Adults

Introduction

Older adults with diabetes are at an increased risk of developing certain geriatric syndromes. Diabetes itself can contribute to developing or exacerbating these syndromes, while age-related changes further compound the risk. These syndromes can have a significant impact on the well-being and functional status of older adults with diabetes.

What Are Geriatric Syndromes?

Geriatric syndromes refer to a collection of health conditions or issues that are commonly seen in older adults. These syndromes are not specific diseases but rather a combination of various symptoms and functional impairments that can affect the overall well-being and quality of life in older individuals. Geriatric syndromes are often multifactorial, meaning they result from a combination of physiological, psychological, and social factors. They can be caused by age-related changes in the body, chronic medical conditions, functional decline, cognitive impairment, and other factors.

Here are some geriatric syndromes commonly seen in older adults with diabetes:

• Falls and Fall-Related Injuries: Diabetes can affect balance, sensation, and muscle strength, increasing the risk of falls. Additionally, complications like diabetic neuropathy (nerve damage) can lead to reduced sensation in the feet, making it harder to detect hazards and increasing the likelihood of falls and subsequent injuries.

• Frailty: Older adults with diabetes may be at a higher risk of frailty due to the chronic inflammatory state associated with diabetes, metabolic changes, and complications like cardiovascular disease and kidney disease. Frailty can lead to functional decline, increased vulnerability, and adverse health outcomes.

• Cognitive Impairment: Diabetes has been linked to an increased risk of cognitive impairment and dementia. Chronic high blood sugar levels and poor glucose control can contribute to brain-related changes and vascular damage, increasing the risk of cognitive decline.

• Incontinence: Diabetes can affect the nerves and muscles involved in bladder control, leading to urinary incontinence. It also increases the risk of urinary tract infections, which can further contribute to incontinence.

• Polypharmacy: Older adults with diabetes often have multiple comorbidities and may require multiple medications. This increases the risk of polypharmacy, potentially leading to drug interactions, medication non-adherence, and adverse effects.

• Malnutrition: Older adults with diabetes may face challenges in managing their diet due to factors such as poor appetite, difficulty preparing meals, or dietary restrictions. This can increase the risk of malnutrition and nutrient deficiencies.

• Delirium: Older adults with diabetes are at an increased risk of developing delirium, particularly during acute illness or hospitalization episodes. High or low blood sugar levels, medication changes, and other factors can contribute to delirium in this population.

What Are the Complications of Geriatric Syndromes in Older Adults?

Complications related to diabetes can be particularly significant in older adults due to age-related changes, reduced physiological reserves, and the presence of other comorbidities. Some common complications that older adults with diabetes may experience include:

• Cardiovascular Complications: Diabetes significantly increases the risk of cardiovascular diseases such as coronary artery disease, heart attack, stroke, and peripheral artery disease. Older adults with diabetes are more likely to have underlying cardiovascular risk factors and may experience more severe manifestations of these complications.

• Diabetic Neuropathy: Nerve damage caused by diabetes, known as diabetic neuropathy, can lead to various complications. Peripheral neuropathy affects the nerves in the feet and legs, leading to loss of sensation, foot ulcers, and an increased risk of infections and lower limb amputations. Autonomic neuropathy can affect various bodily functions, including digestion, bladder control, and blood pressure regulation.

• Diabetic Retinopathy: The blood vessels in the retina can be damaged by diabetes, leading to diabetic retinopathy. In advanced stages, it can cause vision loss or blindness. Older adults with diabetes may already have age-related eye conditions, which can further complicate the management of diabetic retinopathy.

• Kidney Disease (Diabetic Nephropathy): Diabetes is one of the leading causes of kidney disease. Over time, high blood sugar levels can damage the small blood vessels in the kidneys, impairing their function. Older adults with diabetes and kidney disease may require specific interventions, such as medication adjustments and dietary modifications, to manage their condition.

• Cognitive Impairment and Dementia: Diabetes is associated with an increased risk of cognitive impairment and dementia, including Alzheimer's disease. Older adults with diabetes may experience accelerated cognitive decline compared to those without diabetes.

• Infections and Delayed Wound Healing: Diabetes can weaken the immune system and impair the body's ability to fight infections. Older adults with diabetes are more sensitive to skin infections, urinary tract infections, and respiratory infections. Poor circulation and nerve damage can also lead to delayed wound healing, increasing the risk of infections and complications.

How to Manage Older Adults With Uncontrolled Diabetes?

Managing older adults with worsening glycemic control requires a comprehensive approach that addresses both medical and non-medical factors. Here are some strategies to consider:

• Medication Adjustment: Review the individual's current diabetes medications and consider adjustments if necessary. This may involve titrating the dosage of existing medications, adding new medications, or switching to alternative medications that may be more effective in controlling blood sugar levels. Consult with an endocrinologist or diabetes specialist for expert guidance in medication management.

• Nutritional Counseling: Collaborate with a registered dietitian or nutritionist to provide individualized nutritional counseling. Assess the individual's dietary habits, preferences, and challenges and develop a meal plan that supports better glycemic control. Emphasize portion control, balanced meals, and the importance of carbohydrate counting or glycemic index/load awareness.

• Physical Activity: Encourage regular physical activity tailored to the individual's capabilities and preferences. Engaging in regular exercise can help improve insulin sensitivity and glycemic control. Consult with a physical therapist or exercise specialist to develop an exercise plan that is safe and appropriate for the older adult.

• Self-Monitoring of Blood Glucose: Reinforce the importance of self-monitoring of blood glucose levels. Ensure that the individual understands how to use a glucose meter, interpret the readings, and take appropriate actions based on the results. Regular monitoring allows for better tracking of glycemic control and enables adjustments to the treatment plan as needed.

• Adherence Support: Assess medication adherence and address any barriers that may be affecting the individual's ability to adhere to their prescribed treatment plan. Simplify medication regimens when possible, provide medication reminders, and educate the individual and their caregivers on the importance of consistent adherence.

• Geriatric Assessment: Consider a comprehensive geriatric assessment to evaluate other factors that may impact glycemic control, such as cognitive function, functional status, polypharmacy, and social support. Addressing these factors through appropriate interventions, such as cognitive aids, medication reconciliation, and caregiver involvement, can help improve glycemic control.

Conclusion

Older adults with diabetes should receive regular comprehensive geriatric assessments to identify and address these geriatric syndromes. Multidisciplinary care involving healthcare providers, including endocrinologists, geriatricians, and other specialists, can help optimize diabetes management and prevent or manage geriatric syndromes in this population. Lifestyle conversions, medication adjustments, and coordination of care are vital components of a comprehensive approach to the health of older adults with diabetes.
