A chronic disease of the fatty tissue that affects almost only women, causes pain, and is not eliminated by diet or exercise. It is not obesity, it is not cellulite and it is not fluid retention. Here is the essential picture, and the full map to go deeper into each part.
Lipedema is a chronic disease of the fatty tissue that causes an abnormal, symmetrical build-up of fat in the legs, hips and buttocks, and sometimes the arms. It affects almost exclusively women, hurts when pressed and causes heaviness, spares the feet and hands, and is not eliminated by diet or exercise.
One point that has changed in recent years and is still misreported in many places: lipedema is not an oedema, despite its name. Nor is it a venous disease or a disorder of the lymphatic system. It is a disorder of the adipose tissue, and that distinction is what explains why it does not respond to what does work in lymphoedema or in venous insufficiency.
It is recognised as a disease with its own code in the World Health Organization's International Classification of Diseases: ICD-11, code EF02.2 (lipoedema), within the non-inflammatory disorders of subcutaneous fat. The ICD-11 was published in 2018 and has been in force since 1 January 2022. Having its own code means it is not a variant of being overweight nor a finding without clinical standing: it is a condition with clinical criteria, a diagnosis and a treatment.
You will find it spelled both ways: lipedema in American English and lipoedema in British English, which is the spelling the WHO uses. They are the same condition.
You do not need to be a doctor to suspect it. These are the features that set it apart from simply having larger legs:
Recognising several of these is not a diagnosis, but it is a reason to seek advice. Each sign, with detail on how it feels, is developed in the symptoms of lipedema.
Lipedema is chronic and has no cure, but its symptoms can be treated. The options fall into two broad routes, which are not mutually exclusive:
Compression garments, manual lymphatic drainage, low-impact exercise and control of weight and inflammation.
It is the basis of management and can improve pain, heaviness and mobility, although it does not reduce the affected tissue.
Both routes, with the criteria for each and what to expect, in lipedema treatment.
Almost every patient arrives at the clinic after years of being told it was something else. This is the table that helps most to sort out the difference:
| Lipedema | Cosmetic cellulite | Obesity | Lymphoedema | |
|---|---|---|---|---|
| Painful on pressure | Yes, it is the central feature | No | No | Not usually |
| Symmetry | Bilateral and symmetrical (one side may be somewhat more marked) | Bilateral | Generalised | Usually asymmetrical |
| Feet and hands | Spared | Spared | May be affected | Affected |
| Easy bruising | Common | No | No | No |
| Responds to diet | Volume goes down, but the disproportion and the pain remain | Improves partially | Responds | The oedema does not change |
No single feature confirms or rules out the diagnosis: easy bruising and palpable nodules are common, but they are not validated diagnostic criteria. What is popularly called "fluid retention" corresponds to the last column: lymphoedema. The detailed comparison is in difference between lipedema and cellulite and in lipedema and fluid retention.
It is described along two separate axes that are often mixed up: the stage (1 to 4) describes the appearance of the skin and the tissue; the type (I to V) indicates which areas are affected. They are independent: you can have stage 1 with type III.
| Stage | Appearance of the skin and tissue |
|---|---|
| Stage 1 | Smooth surface, with thickened subcutaneous tissue and small nodules on palpation. |
| Stage 2 | Uneven surface, with larger nodules and visible indentations. |
| Stage 3 | Clearly hardened tissue, with lobes of fat that distort the contour. |
| Stage 4 | The above together with an associated lymphoedema component (lipo-lymphoedema). Some classifications describe only three stages and treat this as a separate entity. |
| Type | Area affected |
|---|---|
| Type I | Hips and buttocks |
| Type II | From the hips to the knees |
| Type III | From the hips to the ankles, with a visible cut-off at the ankle |
| Type IV | Arms |
| Type V | Knee to ankle only (calves); it is uncommon |
Important: the stage describes, it does not measure severity. Pain can be intense at stage 1 and manageable at stage 3. See the 4 stages and 5 types of lipedema in detail.
Most of the information about lipedema in circulation comes from elsewhere. In 2023 our team published a study of 969 participants with lipedema in Spain (967 women and 2 men), carried out by questionnaire through the main patient associations (The Advanced Care Study, in the International Journal of Environmental Research and Public Health), to find out what happens here. These are three of its results:
That second figure says the most about the condition: the problem is not that lipedema is hard to recognise, it is that it is little known. If you have spent years being told it is a matter of willpower, the problem was never yours.
Being able to put a name to what is happening to you is the first step. The next one, if you want to take it, is this:
There is no single cause. There is a clear genetic component (it is common to find the same body pattern in mothers, grandmothers and sisters) and a hormonal trigger: the first signs usually appear at puberty, and pregnancy and the menopause are the moments when it becomes most evident. What it is never is the consequence of having eaten badly.
The full mechanism, with what we know and what we still do not, in the causes of lipedema.
The diagnosis is clinical: it is reached through the patient's history and a physical examination by an experienced professional. No blood test or imaging study can confirm it. Tests serve to rule out other causes and to plan.
In our clinic that process incorporates a 3D body scanner, which allows change to be measured objectively, and a vascular study with duplex ultrasound carried out by Dr Marta Zaplana, angiologist and vascular surgeon, to establish the state of the venous system before considering anything.
The full process, step by step, in lipedema diagnosis.
It is the first question after a diagnosis, and it is almost never answered with data. The honest answer is that it is not an inevitably progressive disease. The prospective study with the longest follow-up published to date (Forner-Cordero and Muñoz-Langa, Vascular Medicine, 2025) measured leg volume in 100 patients over a mean of 4.6 years: 62% remained stable, 28% progressed and 10% improved.
That same study provides the most useful finding for a patient: age was not associated with progression, whereas weight gain and abdominal fat were. The more the body mass index and the waist-to-height ratio rose, the more the lipedema progressed. Put another way, what was related to the course of the disease was not time, but change in weight. In that work no association was observed between maintenance therapies and the change in volume, which does not diminish the value of conservative management for pain, heaviness and mobility: those are different goals.
One caveat that matters: what can appear over the years is an associated lymphoedema component, usually described as stage 4. There is no evidence that conservative treatment prevents it, but it is a reason not to lose follow-up and to seek advice if changes appear.
The follow-up data, with the exact percentage of patients who remain stable, progress or improve, is in the stages of lipedema.
You can have lipedema at a normal weight: in our study, 38.6% of participants were of average weight. Losing weight does reduce volume, in the legs too, but the disproportion and the pain remain. That is why diet is part of management and not the solution.
Cellulite does not hurt and does not cause bruising. Lipedema is a recognised disease, with pain as its central symptom. Confusing the two is what delays diagnosis by years.
Lipedema requires techniques that respect the lymphatic vessels, and a vascular assessment beforehand to rule out venous disease. A conventional cosmetic liposuction is not designed for this tissue.
It has a genetic component and no cure, but its symptoms can be treated and its course can be modified. Chronic does not mean there is nothing to be done.
Every piece of this summary has its full development, reviewed by the medical team.
A chronic disease of the fatty tissue that causes an abnormal, symmetrical build-up of fat in the legs, hips and buttocks, and sometimes the arms. It affects almost exclusively women, hurts when pressed and causes heaviness, spares the feet and hands, and is not eliminated by diet or exercise.
No. It is a chronic disease and there is no cure. Its symptoms can be treated, and appropriate management makes it possible to control pain and preserve mobility and quality of life.
It affects almost exclusively women. In men it is very uncommon and tends to be associated with situations involving hormonal disruption: in our study, 2 of 969 participants were men. The hormonal component is one of the keys to the condition.
No. In obesity fat is distributed generally, including the trunk, it does not hurt and it responds to a calorie deficit. Lipedema is symmetrical, disproportionate, painful and spares the feet and hands. You can have lipedema at a normal weight, and you can also have both at once.
An angiologist and vascular surgeon, a plastic surgeon or other specialties can diagnose it, always with specific experience in lipedema. In our study of 969 participants, 50.4% were diagnosed by a vascular surgeon. See lipedema diagnosis.
Four stages are described according to the appearance of the skin and the tissue, from 1 (smooth surface) to 4 (with associated lymphoedema). They are independent of the five types, which indicate the areas affected. The stage describes, it does not measure severity.
Low-impact exercise and, especially, activity in water: hydrostatic pressure aids drainage and reduces the load on the joints. The aim is to maintain mobility and control inflammation, not to lose volume from the affected areas.
Its onset cannot be prevented, because there is a genetic component. What can be done is to act early on the symptoms and avoid factors that aggravate them: weight gain and abdominal fat are the factor that has been associated with progression of volume.
Too long. In our study of 969 participants in Spain, 51.2% needed to consult three or more different specialists before obtaining a diagnosis, and 33.7% more than five.
