    Postoperative fatigue affects one-third of patients after abdominal surgery, persisting for a month. This fatigue correlates with weight loss and lower serum transferrin levels, indicating potential nutritional impacts.

    Area of Science:

    • Surgical outcomes
    • Patient recovery
    • Metabolic changes

    Background:

    • Postoperative fatigue is a common yet poorly understood complication following elective surgery.
    • Understanding the factors contributing to fatigue is crucial for improving patient recovery and quality of life.

    Purpose of the Study:

    • To quantify subjective fatigue levels in patients undergoing elective abdominal surgery.
    • To identify potential correlations between postoperative fatigue and various physiological and nutritional markers.

    Main Methods:

    • A cohort of 36 healthy patients undergoing elective abdominal surgery were assessed.
    • A constructed fatigue scale was used to measure subjective fatigue preoperatively and at 10, 20, and 30 days postoperatively.
    • Body weight, triceps skinfold, arm muscle circumference, and serum transferrin levels were measured.

    Main Results:

    • One-third of patients experienced significant fatigue throughout the first postoperative month.
    • Fatigued patients exhibited greater weight loss (P < 0.001) and lower serum transferrin levels (P < 0.02).
    • No significant correlation was found between fatigue and changes in hemoglobin, lymphocyte count, albumin, electrolytes, or minerals.

    Conclusions:

    • Postoperative fatigue is a notable syndrome following abdominal surgery, linked to nutritional status indicators.
    • Predicting the development of late postoperative fatigue based on preoperative factors was not possible in this study.
    • Further research into therapeutic interventions for postoperative fatigue syndrome is warranted.
