Our understanding of lipedema and its diagnostic criteria has evolved over the years thanks to international studies and the involvement of multidisciplinary working groups. This document summarizes the consensus established in various countries as well as the most recent recommendations for an accurate diagnosis of this still under-diagnosed condition.
The Dutch consensus laid the foundations for understanding lipedema by highlighting the disproportionate distribution of subcutaneous fat between the upper and lower body, sparing the hands and feet. Allodynia (increased sensitivity to touch) and significant thickening of the subcutaneous fat, often marked by an abrupt cutoff at the joints, are key criteria reinforcing the diagnosis.
This consensus broadened the diagnostic criteria by emphasizing pain during the "pinch test" as a fundamental element. According to their research, lipedema presents no free fluid edema on ultrasound, unlike other pathologies such as obesity or lymphedema.
The American criteria include elements such as:
The German guidelines adopt a rigorous clinical approach, emphasizing the following points:
Recent updates (Herbst, 2024) have introduced a paradigm shift. Rather than focusing on a hypothetical edema, the current approach aims to address the primary symptoms:
To establish an accurate diagnosis, it is essential to differentiate lipedema from the following conditions:
Although ultrasound can provide valuable insights into subcutaneous tissues, it should not be considered a standalone diagnostic tool. Current studies show that the tissue structure in lipedema exhibits significant differences compared to other conditions, though standardized criteria are still lacking.
The diagnosis of lipedema relies on a meticulous clinical approach and the rigorous exclusion of other pathologies. Recent advancements highlight the importance of comprehensive care, encompassing both physical and psychological aspects. The improvement of diagnostic tools and international collaboration will continue to play a key role in the recognition and treatment of this complex condition.
