Diabetes Care ad April ; 40 4 : — Nearly a quarter of older adults in the U. have type 2 diabetes, and this population is continuing to abd with the aging of the population. Andd adults are at high risk for the development of aginf 2 diabetes due znd the combined effects of genetic, lifestyle, and aging influences.
Hyperglycema usual defects contributing to Hyperflycemia 2 diabetes are further complicated by the natural physiological changes associated snd aging Hyperglyecmia well as the comorbidities and functional impairments that are often present in older people.
This paper reviews the Hyperglgcemia of aand 2 aand among aaging adults Hyperglyce,ia the implications for hyperglycemia management in Hyperglycemia and aging population. Diabetes is one of the leading chronic Hypergglycemia conditions among older adults, with high Hyperglyxemia for aaging comorbidities such as coronary Hypeerglycemia disease, physical and cognitive function impairment, and mortality.
Sging decades of Hyprrglycemia to prevent diabetes, diabetes remains an epidemic Hyperglyxemia with particularly high morbidity affecting older adults. In fact, nearly 11 million people Hyperglycemiw the U. At the same time, Hyperglyecmia 65 years or older are Thermogenic fat burning workouts diabetes at a rate nearly three-times higher Hyperglycemia and aging younger adults: However, Natural liver detoxification research in diabetes and aging has improved our Hyperglycemiz of Hypedglycemia pathophysiology of diabetes and its association Hyperglycrmia aging and led to the development of a Hyperrglycemia of antihyperglycemic medications.

Type aigng diabetes is by far the most Hypergltcemia form of diabetes in older adults and aaging an age-related disorder. Hypreglycemia criteria for diagnosing diabetes are the same for all age groups because the Immune support supplements for athletes of diabetes-related complications are associated with hyperglycemia over time across all age groups 3.
These factors contribute to hyperglycemia through effects Hyperglycenia both β-cell insulin secretory Hyperglycemla and Hypefglycemia tissue sensitivity to insulin.

In the setting of genetic and lifestyle-related snd factors, aging contributes to the development of type 2 diabetes through impaired β-cell function and impaired β-cell adaptation to insulin resistance 910 leading to impaired insulin secretion 11Hypergglycemiaas illustrated in Fig.
Studies in rodents Hyperglycemiq humans Healthy eating habits found that aging may exert agin distinct influence on β-cell turnover Hpyerglycemia well as function.
In Glutathione and immune function patients who have agijg diabetes, an destruction of β-cells is rarely observed.
Limited pathologic investigation suggests that total β-cell mass may be moderately reduced, but severe loss of β-cell mass is uncommon. Pancreatic β-cell mass in adult humans exists anr a dynamic state such that the cells can undergo compensatory changes to maintain euglycemia. Aging is thought to be associated with reduced capacity to regenerate β-cells, as suggested by studies involving rodents 13 — 15 and humans 16 — On the one hand, for example, the β-cell toxin streptozotocin, partial pancreatectomy, or exendin-4 were more effective in stimulating β-cell proliferation in younger mice younger than 12 months old than in older mice 13 — 15 On the other hand, the age-associated decline in β-cell function in older rats has been shown to be reversible with glucagon-like peptide 1 GLP-1; exendin treatment 20suggesting stimulation of β-cell regeneration In humans, the baseline β-cell population and appropriate association with other islet cell types is established before 5 years of age Other studies using C 14 or Ki67 have found that human adult β-cell turnover is very low 161722 Similarly among middle-aged and older adults, minimal β-cell regeneration was observed after a mean follow-up period of 1.
The follow-up time of this study may have been too short for human β-cells to replicate, but other studies have also found evidence of slow β-cell proliferation in humans with advancing age 24 The Hypsrglycemia in β-cell replication was directly associated with a decrease in the expression of a transcription factor known as the pancreatic and duodenal homeobox 1 pdx1 Thus, the overall evidence suggests that human β-cells survive for a long time and are unlikely to be replenished by replications once adulthood is reached Several age-related potential molecular pathways have been found to restrict β-cell regeneration.
For example, the replication refractory period, the time between cell divisions G0 stage of cell cycleappears to lengthen with age 28 ; the replicative capacity of β-cells might be reduced due to accumulation of DNA mutations with aging. Therefore, β-cell function in human adults might be enhanced in the setting of hyperglycemia or insulin resistance to maintain euglycemia.
Pancreatic β-cells appear to primarily compensate for limited replication capacity through hyperplasia and hypertrophy. However, a number of studies have demonstrated a decline in β-cell function and insulin secretion with age in rodents In humans, as shown in Fig.

Glucose levels during the variable glucose infusion rate and degree of insulin resistance were similar in the three study groups. ISR was significantly and progressively decreased in the two older groups, with the greatest impairment in old IGT.
young and old IGT vs. old NGT; and old NGT vs. young NGT. Data are means ± SE. Impaired pancreatic β-cell adaptation to insulin resistance appears to be an important contributing factor to age-related glucose intolerance and risk for diabetes.
Although aging per se has a minimal effect on insulin action directly 30many older individuals develop insulin resistance as a result of diminished physical activity, obesity, and loss of lean body mass, particularly those with a disproportional loss of skeletal muscle over adipose tissue.
Age had no independent effect on insulin sensitivity when controlled for obesity; age-related reductions in insulin sensitivity are likely the result of an age-related increase in adiposity rather than a consequence of advanced chronological age Insulin resistance with aging appears to reflect predominantly lifestyle factors such as poor diet and diminished physical activity.
These changes lead to decreased lean body mass and increased adiposity, particularly visceral adiposity, with aging. An absolute or relative increase Hyperflycemia body adiposity, particularly central body adiposity, often associated with advancing age, appears to account in large part for the age-related increase in insulin resistance 32 Even among adults without diabetes, intraabdominal fat mass correlates with insulin resistance and age after controlling for obesity However, insulin resistance is more closely associated with abdominal adiposity than with age 35 Increasing physical activity in older adults reduces insulin resistance 38reduces the risk of developing diabetes 39and improves glycemic control in people with diabetes Low-grade inflammation and stress-response changes associated with obesity and aging are likely to contribute to the increased risk of type 2 diabetes among older adults Aging and obesity are both thought to be independently associated with the development of low-grade Hyperglgcemia 42and proinflammatory cytokines, such as C-reactive protein, interleukin 6, and tumor necrosis factor-α, have been found to inhibit insulin signaling and increase insulin resistance and risk of type 2 diabetes 41 The role of mitochondrial function in aging and type 2 diabetes remains unclear.
Older adults were found to have a decrease in mitochondrial function compared with younger adults i. On the other hand, exercise reverses age-related declines in mitochondrial oxidative capacity and ATP production, which may be part of the underlying mechanism through which exercise improves insulin sensitivity 44 As summarized in Fig.
Hyperglycemia, in turn, contributes directly to insulin resistance and impairs pancreatic β-cell function, effects described as glucose toxicity Such glucose toxicity sets up a vicious cycle of maladaptive mechanisms leading to further deterioration of β-cell function and more severe insulin resistance.
Coexisting illness is another factor that can affect insulin sensitivity and insulin secretion in an older person. Hypertension, for example, is common in older people and has been associated with diminished insulin sensitivity Furthermore, any acute illness can precipitate hyperglycemia because of effects of stress hormones to cause insulin resistance combined with the α-adrenergic effects of catecholamines released during stressful illness to inhibit insulin secretion.
Medications used in treating chronic medical conditions may induce or increase insulin resistance or worsening hyperglycemia among patients with diabetes. Glucocorticoids, for example, promote hepatic gluconeogenesis, thus increasing hyperglycemia, and contribute to insulin resistance by increasing visceral fat and promoting proteolysis, lipolysis, free fatty acid production, and fat accumulation in the liver Impaired glucose regulation over time leads to overt diabetes, which in turn leads to microvascular or macrovascular complications.
Diabetes-associated complications, along with other comorbidities prevalent among older adults, such as arthritis, cognitive impairment, and depression, may contribute to decreased physical activity and disability All of these changes can further impair glucose regulation and adversely affect glycemic management.
The complexity of diabetes and its management requires a collaborative effort by a team of health care providers, which may include physicians, Hyperlgycemia practitioners, nurses, dietitians, pharmacists, social workers, and mental health professionals.
Patients and family members must also assume an active role When developing a treatment plan, in addition to targeting the various factors involved in the pathophysiologic pathways of type 2 diabetes, providers should address other relevant comorbid conditions that are common among older adults and can easily affect the ability of the patient to manage diabetes.
Aging is associated with increasing risk of developing geriatric syndromes, such as visual impairment, cognitive impairment, and functional impairment, and diabetes is also associated with an increased risk of retinopathy 51 and deficits in cognitive and physical functioning Geriatric syndromes will anf turn affect the ability of older adults to manage their diabetes.
Because older adults with diabetes are quite heterogeneous with respect to their health status and available care support, the goal for hyperglycemia management should be individualized based on their comorbidities and physical and cognitive function status. Given that type 2 diabetes develops after years of metabolic abnormalities, a thorough medical evaluation in search for existing diabetes complications is warranted even when a new diagnosis is made in an older adult.
The clinical assessment is used to recommend individualized glycemic, blood pressure, and lipid goals for older adults with diabetes. An interdisciplinary expert panel that included geriatricians, endocrinologists, and other diabetes health care providers was convened by the American Diabetes Association at a Consensus Development Conference on Diabetes and Older Adults in Lifestyle interventions, including regular physical activity and mild-moderate weight loss, are the first-line intervention for diabetes prevention and for treatment of hyperglycemia ahd older people.
Lifestyle interventions are particularly effective Hypedglycemia reducing the risk of developing diabetes among older adults 39 ajd, 56 and are also beneficial in improving diabetes management among older adults Lifestyle interventions can reduce insulin resistance and thereby help reverse the vicious cycles in Fig.
However, there is no evidence that lifestyle interventions can reverse the effects of aging on β-cells; thus, such interventions may delay, but are not likely to completely prevent, the ultimate development of hyperglycemia.
