Lipedema is a chronic and often misunderstood fat disorder that primarily affects women. It involves the abnormal accumulation of fat, typically in the lower body—hips, buttocks, thighs, and sometimes the arms—while sparing the hands and feet. It often leads to pain, tenderness, easy bruising, and a disproportionate body shape. Importantly, lipedema fat is resistant to diet and exercise and is not the result of lifestyle choices alone.
Key Characteristics of Lipedema:
- Symmetrical fat accumulation: Often from the waist down, sparing the feet.
- Pain and tenderness: Affected areas may be painful to touch.
- Bruising: Easy bruising due to fragile capillaries.
- Resistance to weight loss: Fat persists even after significant weight loss through diet or exercise.
- Progressive condition: It may worsen over time, particularly with hormonal changes (e.g., puberty, pregnancy, menopause).
How does bariatric surgery interact with lipedema?
Bariatric surgery is a powerful tool for weight loss in individuals with obesity. However, its impact on lipedema specifically is complex and depends on the individual’s condition. Potential benefits of bariatric surgery for lipedema include:
- Weight loss in non-lipedema areas:
- Bariatric surgery helps reduce general body fat, particularly visceral and subcutaneous fat in unaffected areas (like the abdomen).
- This may improve mobility, joint pain, and overall health.
- Improved comorbidities:
- Obesity-related conditions (diabetes, hypertension, sleep apnoea) may improve, which can indirectly ease the overall burden of lipedema. This can also increase the safety of future surgeries.
- Better eligibility for surgical treatments like liposuction:
- Some providers prefer patients reach a stable post-bariatric weight before undergoing lipedema-specific liposuction, which is more targeted.
There are however some limitations and risks when treating lipedema with bariatric surgery. The main point to note is that lipedema fat usually persists after bariatric surgery. The aim of bariatric surgery in these cases is to decease the burden of obesity fat so that the lipedema pathological fat can be more easily and effectively addressed by the plastic and reconstructive surgeon. During this time body disproportion may become more pronounce. I.e. As non-lipedema fat is lost, the contrast with affected areas can increase.
So what is the evidence and/or expert opinion?
- A 2020 study in Obesity Surgery found that lipedema patients lost less fat in the affected limbs post-surgery compared to other regions.
- Bariatric surgery does not treat the pathophysiological cause of lipedema—namely, the abnormal fat cell behaviour and lymphatic issues.
- Lipedema-specific liposuction (tumescent or water-assisted) is currently the most effective surgical treatment for directly addressing lipedema fat.
Therefore bariatric surgery can help with obesity-related health issues and improve quality of life, but it does not effectively treat lipedema fat. However, patients with both conditions may still benefit from surgery but should have realistic expectations and consider lipedema-specific interventions (e.g., specialized liposuction, compression therapy, lymphatic drainage) after the weight loss post bariatric surgery has plateaued. It is important to engage with a multidisciplinary team including bariatric specialists, vascular surgeons, plastic surgeons and lymphedema therapists to ideally manage these complex cases.
