Introduction
Lipoedema is a chronic, progressive disorder of adipose tissue, often misdiagnosed as obesity or lymphedema.(figure 1)
Characterized by symmetrical fat deposition in the limbs—sparing the hands and feet. It causes pain, easy bruising, and mobility challenges. Early diagnosis is crucial to halt progression and prevent debilitating complications.[1]
Unlike edema, lipoedema stems from a genetic disruption in fat distribution. First described by Dr. Allen in 1940 as 'bilateral leg enlargement due to subcutaneous fat accumulation,' it remains underrecognized despite its profound physical and psychological toll.[2]

Prevalence
The true prevalence of lipoedema remains uncertain and is a subject of ongoing research due to challenges in clinical recognition, underreporting, and frequent misdiagnosis—often as general obesity. While some large-scale estimates suggest that lipoedema may affect 11–18% of adult women, with virtually no prevalence in men, other studies report considerably lower rates, reflecting inconsistencies in diagnostic approaches.[3]
A review by Cifarelli et al. (2025) emphasizes the widespread underrecognition of the condition, noting that many affected individuals are either overlooked or misclassified.[4] Similarly, Carvalho (2024) suggests that lipoedema, though often unrecognized, may be relatively common, citing prevalence figures of 5–15% in selected European populations.[5]
Meanwhile, observational studies in clinical settings show even greater variation: prevalence in outpatient clinics has been estimated at 7–10%, and hospital-based cohorts report rates between 8% and 18%.[6][7][8]
For instance, a regional survey in southern Germany identified a 10% prevalence among adult women, further supporting the possibility that lipoedema is significantly more common than currently documented in healthcare databases.[9]
Aetiology
Lipedema is considered as genetic inheritance, either X-linked dominant or autosomal dominant. A study made on 330 family members of patients with lipoedema by Child et al., described the Autosomal dominant as a major mode of inheritance, with a few described the instances of the X-linked dominant.[10]
A limited number of cases with POU1F1/PIT-1 gene mutations in short-staffed mothers, with no phenotypic features identified in affected male offspring who inherited the gene, as well as in affected daughters who possess normal height, have been documented. In addition, lipoedema has been associated with Williams syndrome, due to a microdeletion in approximately 1.6 million base pairs in chromosome arm 7q11.23, encompassing the ELN (elastin gene).[11]
Classification
Lipoedema is classified into 5 types and 4 main stages according to a review by Buso G et al.(2019).[12](figure 2)
The 5 types of liboedema based on distribution are :
- Type 1: lipoedema fat tissue accumulates around the hips and buttocks.
- Type 2: accumulation involves the area from hips to knees.
- Type 3: a hip to ankle phenotype is observed.
- Type 4: Approximately 80% of affected women have an additional involvement of arms.
- Type 5: while it is rare to find fat dominating the calf region only.
Depending on severity, the lipoedema is classified into 4 stages:
- Stage 1: skin may be smooth and soft, but the underlying hypodermis is enlarged.
- Stage 2: skin may be indented over palpable pearl‐sized nodules (“peau d'orange”).
- Stage 3: characterized by folds and divots over deforming, larger fat masses, frequently associated with functional limitations.
- Stage 4: characterized by the development of concomitant lymphedema (lipolymphedema); as presents with foot oedema, a hallmark positive Stemmer sign, and often accompanying features like cellulitis or papillomatosis characteristic of advanced lymphedema.
Clinical Presentation
As lipoedema is characterized by gynoid-type fat tissue localization, typically affecting the hips, buttocks, thighs, and lower legs, leading to a disproportionate waist-hip ratio (<1) and a marked circumference disparity between the hips and waist (“riding breeches”), with a distinct “cuff sign” at the ankle where normal and abnormal tissue sharply separate.[12]
The disease progression is heterogeneous and highly variable from one individual to the other. Some women in certain instances showing fixed, mild symptoms in the long run, while in other instances there is slow progression with stress-induced sudden exacerbations, such as in surgical cases or pregnancies.[13]
- Patient Symptoms and Complains[12]:
- Pain and Sensitivity: Patients commonly report easy bruising, moderate to severe pain upon digital pressure on affected limbs, and spontaneous pain.
- Orthostatic Edema: A hallmark feature causing leg heaviness, fatigue, and discomfort, exacerbated by warm weather and exercise, unrelieved by limb elevation, but significantly alleviated by lipoaspiration.
- Pain Mechanisms: Pain may result from mechanical forces, biochemical effects on sympathetic nerve fibers, inflammation, or microangiopathy causing inadequate blood supply to peripheral nerves, leading to protopathic sensibility disturbance.
- Obesity and Psychological Impact: Increased risk of morbid obesity, with obesity itself as a risk factor for lipoedema; minimal effect of weight loss measures on abnormal fat distribution, often leading to eating disorders, depression, and other psychological complaints.
- Gait and Joint Issues: Excessive fat on buttocks, hips, thighs, and lower legs alters gait, causing mechanical leg axis malalignment, joint stress, knee valgus osteoarthritis, antalgic gait, and feet overpronation, worsened by prevalent hypermobility.
- Skin Complications: Bulging tissue and deep skin folds may lead to skin lesions, maceration, and infections
- Cardiovascular and Metabolic Profile:
- Less severe cardiovascular profile with gynoid fat distribution negatively correlating with insulin resistance compared to abdominal fat.
- Lower fasting triglyceride-rich lipoprotein, lower triglyceride levels, and smaller chylomicron particle size in gynoid fat distribution.
- Low diabetes prevalence despite high average BMI (39 ± 12 kg/m²).
- Normal lipid profile in most patients, with only 11.7% having total cholesterol ≥ 240 mg/dL, compared to higher rates (up to 33.5%) in the general female population.
- Hypertension rates below 30% in stages 2 and 3 lipoedema, absent in stage 1, compared to higher rates (32.4%–60%) in women of similar age and BMI.
- Aortic stiffness reported in one study, potentially contradicting lower cardiovascular risk, possibly due to geographic differences in study populations.
Assessment & Diagnosis
The diagnosis of lipoedema is based on clinical evidence and exclusion criteria. In 2017 [14], the Dutch guidelines firstly extended the list of 6 diagnostic criteria that had proposed by Wold et al. in 1951[15]. Then Buso G et al. proposed a slightly modified version of the list that had published by Halk and Damstra in the Dutch guideline.[12] Diagnostic criteria table of lipedema :
| Medical history (A) (criteria of Wold et al.) | |
| A | 1 Disproportionate body fat distribution |
| 2 No or limited influence of weight loss on fat distribution | |
| 3 Limb pain and bruising | |
| 4 Increased sensitivity to touch or limb fatigue | |
| 5 Nonpitting edema | |
| 6 No reduction of pain or discomfort with limb lift | |
| Physical examination (B, C, D, E) | |
| B | Proximal part of the lower limb |
| 1 Disproportionate fat distribution | |
| 2 Circumferentially thickened cutaneous fat | |
| C | Distal part of the lower limb |
| 1 Proximal thickening of subcutaneous fat | |
| 2 Distal thickening of subcutaneous fat, accompanied by slender instep (cuff sign) | |
| D | Proximal part of the arm |
| 1 Significantly thickened subcutaneous fat in comparison with vicinity | |
| 2 Sudden stop at elbow | |
| E | Distal part of the arm |
| Thickened subcutaneous fat, accompanied by slender back of hand (cuff sign) | |
| Extra criteria | |
| F | 1 Pain when applying bimanual palpation |
| 2 Distal fat tissue tendrils of the knee (popliteus) | |
| Notes: | Extracted from the review of Buso G et al.[12]
Modified from Halk and Damstra.[14] Diagnosis is highly probable when present: A (1 to 6) + (B [1 + 2] or C [1 + 2] or D [1 + 2] or E). In the absence of at most two of these criteria (A to E), the presence of the extra criteria F(1) or F(2) also support the diagnosis. |
Considering the enlargement of lower extremities, the first step towards the diagnosis is to determine whether this enlargement is unilateral or bilateral, as lipoedema is always bilateral and non‐pitting, and other diagnoses that might cause bilateral lower limb with pitting oedema include early lipodermatosclerosis, dependent oedema, limb swelling because of internal (such as thyroid, heart, kidney) diseases, and oedema because of certain medications.[16]
Then exclude other diseases and syndromes that cause the same lower limbs enlargement; the following (figure 3) is a diagnostic algorithm (and approach to enlargement of lower extremities).[17]
Management
According to the latest evidences, currently there is no cure for the lipoedema. Yet there is treatment approaches that aims to improve or alleviate symptoms, prevent disease progression, address complications, and manage patient expectations to provide better physical and psychological quality of life.[18]
The treatment approaches is divided into 2 main approaches : Conservative and Surgical treatments. The conservative treatment consists of 5 main areas; life style & physical activity modifications, nutritional education & a diet plan, pharmacological interventions, patient education and Physiotherapeutic approaches as a capstone treatment option in the conservative approach. On the other hand, the surgical approach is primarily consists of liposuction and surgeries for associated varicose veins.[18]
Conservative Treatment
As mentioned before the conservative treatment is consisted of 5 main areas will be discussed in detail later at this section:
- Life style and Physical activity Modifications
- Nutritional Education and Plan
- Pharmacological Interventions
- Patient Education
- Physiotherapy Approaches
1- Life style and Physical activity Modifications
Individuals with lipoedema frequently have a high body mass index and are categorized as overweight or obese. Thus, promoting weight loss and preventing obesity are vital components in managing lipoedema, with recommendations for physical activity being among the first conservative strategies implemented. [18]
Suggested physical activities include swimming, exercises targeting multiple joints on vibrating platforms, using elliptical machines, cycling on stationary bikes, and walking. Moreover, strength training exercises, especially aimed at postural and pelvic floor muscles, are recommended, as individuals with lipedema may possess up to 30% less muscle strength compared to typical individuals.[18]
2- Nutritional Education and Plan
3- Pharmacological Interventions
4- Patient Education
Research indicates that people with lipedema encounter difficulties in psychological adjustment, heightened deficits in both physical and social skills, along with elevated levels of anxiety and depression. Commonly experienced symptoms such as discomfort and sensitivity suggest possible adverse effects on health-related quality of life.[19]
Consequently, alongside conservative and surgical interventions supported by a multidisciplinary team, the care of patients with lipedema should include education and guidance regarding the chronic and progressive nature of the condition, which currently lacks a definitive cure.[19]
