Lipedema, lymphedema, and obesity are distinct conditions that differ in many characteristics described below. They are also overlapping conditions however where all can coexist, leading to more individual variation in symptoms. This is also a simplification – lymphedema can happen for different reasons including congenital and surgical and will be discussed more elsewhere. Someone with obesity may develop lymphedema, just as lipedema can turn into lipolymphedema at later stages. Conversely, though less common, someone can have lymphedema and not see signs of lipedema until later.
Identifying which condition is present can help tailor treatments that will be most effective.
| Lipedema | Lymphedema | Obesity | |
| Laterality | Bilateral | Unilateral/Bilateral | Bilateral |
| Hand/foot involvement | Spares feet and hands which can sometimes create a characteristic “cuffing” appearance | Involves the feet | Involves feet |
| Change with elevation | No change with elevation | Reduces with elevation | No change with elevation |
| Pitting/Non-pitting | Non-pitting (especially early) | Pitting more likely (non-pitting in later stages) | Pitting more likely |
| Symmetry | Symmetric | Can be asymmetric | Usually symmetric |
| Gender differences | Primarily women | Women and men | Women and men |
| Pain | Tender | Non-tender/Infrequent | Non-tender/Infrequent |
| Dermatologic effects | Skin consistency normal but prone to varicosities, telangectasia, easy bruising | Skin can be thicker/firmer | Skin consistency normal but can be associated with metabolic skin conditions like skin tags, acanthosis nigricans, and striae |
| Inflammation | M2 macrophage anti-inflammatory profile that influences fat cell differentiation and are associated with progressive fibrosis | M2 macrophage polarization that regulates lymphangiogenesis and limits fibrosis | M1 macrophage pro-inflammatory |
| Treatment Response | Resistant to diet/exercise, sometimes responsive to lymphatic massage and compression, lymph-sparing liposuction | Primary treatments are decongestive therapy, lymphatic massage, compression | Typically responds to diet/exercise, metabolic intervention |
Inflammatory differences in lipedema and obesity
Major differences here are related to immune cells called macrophages. These white blood cells have many roles in inflammation regulation and signaling, tissue repair, innate and adaptive immunity, and more. Macrophages can be polarized into M1 or M2 macrophages which have opposing roles with M1 being pro-inflammatory to help do things like fight invaders, while M2 are anti-inflammatory and promote healing.
Lipedema and lymphedema both have an M2 macrophage phenotype while obesity is characterized by an M1 macrophage pro-inflammatory profile. The M2 macrophage polarization in lipedema and lymphedema have different consequences with the M2 macrophages of lipedema having a greater effect on fat cell differentiation and is associated with progressive fibrosis while that of lymphedema has a greater effect on the formation of lymphatic vessels (lymphangiogenesis) and limiting fibrosis. Lipedema favors a more metabolically normal profile despite elevated fat levels, while obesity is more associated with metabolic disorders like diabetes and hyperlipidemia. [1, 2]
Lymphatic impact
Both lipedema and lymphedema can coexist, however lymphedema results from impaired lymphatic drainage causing fluid accumulation, inflammation, fibrosis, and secondary adipose expansion, while early stage (I-II) lipedema shows dilated but functionally intact lymphatics without the dermal backflow characteristic of lymphedema. In later stages of lipedema, the lymphatic pumps can become overwhelmed resulting in lipolymphedema.[3-6]
Response to treatment
Unlike obesity, standard weight loss measures like caloric restriction, exercise, and metabolic interventions have minimal effect on lipedema’s abnormal fat distribution, and bariatric surgery cannot reduce the localized fat accumulation or alleviate pain.[7-10] Lymphedema responds to complete decongestive therapy including lymphatic massage and compression garments, which has a lesser impact on lipedema but currently remains a standard treatment.[4]
