[Lipedema pain-the neglected symptom].

Pain, which is a central characteristic of lipedema, allows differentiation from other fat tissue diseases. The analysis of the multiple aspects of pain beyond a quantification of pain scale scores could make molecular disease and therapy mechanisms accessible. Lipedema pain is causally linked to lipedema fat. First robust data show peripheral sensory changes. Tissue weight and systemic inflammation are becoming less likely as causes for the experianced pain. Furthermore, genetics and hormonal influences need to be investigated. Lipedema pain cannot currently be treated with drugs. Physical therapy shows transient relief. Liposuction has been shown to have a long-term effect on pain. The potential of modulating the perception of pain with psychotherapeutic approaches is emerging as a potentially effective new therapeutic approach.
