In such cases, the target goal might be to prevent the symptoms of hyperglycemia (increased urination, increased thirst, and blurred vision), which can adversely affect quality of life. In addition, blurred vision can lead to medication errors, difficulty performing ADLs, and decreased functionality. On the other hand, the blood glucose level shouldn’t be too high. In addition to increasing the risk of complications of diabetes, hyperglycemia is associated with decreased cognition in older adults. Nutrition. Meal planning for people with diabetes focuses on maintaining consistent carbohydrate intake and adjusting medication, particularly insulin, to this intake. Weight loss or maintenance is often a goal. While many older adults with diabetes are overweight, many others, particularly the old old, are underweight, in part because of age-related changes such as decreased taste sensation and salivation. National nutrition surveys have reported that more than 30% of older adults consume less than two-thirds of the recommended intake of calories, calcium, and vitamin A, and more than 20% have low intake levels of iron and vitamin C. Thus, weight gain, rather than weight loss, and adequate nutrition may be management goals for some.
