Background: Lymphedema is a clinical condition associated with a functional or mechanical deficiency of the lymphatic system,
leading to the accumulation of macromolecules in the interstitial space and the consequent retention of liquids. The objective of the
study was to determine changes in the extracellular water/total body water ratio in all extremities and the thorax after intensive
treatment for lymphedema. Method: A clinical crossover study was conducted involving the determination of the extracellular
water/total body water ratio in all extremities and the thorax of 86 patients with clinical diagnosis lymphedema, stage II and III at
the Clínica Godoy-Sao Jose do Rio Preto-Brazil in January until December 2020. Evaluations were performed with multi-segment
bioimpedance analysis before and after intensive treatment for lower limb lymphedema using the Godoy Method. Results:
Significant reductions were found after treatment using all assessment methods (volumetry, circumference measurements and
bioimpedance analysis). Conclusion: The intensive treatment of lower limb lymphedema using the Godoy Method results in a
reduction in edema throughout the body, as demonstrated by bioimpedance analysis of all extremities and the trunk. Therefore, the
method affects the lymphatic system and the response is systemic.
