Abstract:
This review aimed to evaluate the level of fatigue in adults with type 2 diabetes measured by the validated Diabetes Symptom Checklist (DSC)and related factors. Ten studies were included. Both DSC (n = 4) and the revised (n = 6) have been used to measure fatigue. When the latter was used (n = 1082), the pooled level of fatigue was 1.77 (on a 0-5 scale). When the former was used (n = 674), the pooled level of fatigue was 1.73 (on a 0-10 scale). Participant demographics (e.g., gender), health information (e.g., BMI), and diabetes-specific factors (e.g., A1C and diabetes distress) were associated with fatigue. Fatigue was negatively related to self-care behaviors. The prevalence of significant fatigue remains unclear due to a lack of a cut-off point of the instrument. Future research is warranted to identify the threshold for clinically significant fatigue and investigate the causal relationship. Nurses are recommended to perform a routine assessment of fatigue.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
