What is lipedema?
Lipedema is a chronic fat tissue disease characterized by painful, sensitive, and disproportionate increase of fatty tissue in the legs and sometimes arms, primarily seen in women. The term “chronic” here indicates that the condition is distinct from a short-term edema attack. The phrase “fat tissue disease” is important to differentiate lipedema from simple excess weight.
The clinical picture we often observe is as follows: The patient may lose weight from the upper body, and their face and torso become thinner; however, the hips, thighs, knee area, or calves do not become thinner as expected. Pain in the legs, sensitivity to touch, easy bruising, and a feeling of heaviness throughout the day may accompany this picture. This situation can be dismissed for years with explanations like "I can't lose weight," "my body type is like this," or "I have too much cellulite."
The diagnosis of lipedema is often made through a well-taken patient history and careful physical examination. It is not a disease diagnosed by blood tests or a single imaging method. Therefore, the patient's descriptions, fat distribution in the body, presence of pain-sensitivity, condition of the feet, and associated diseases are evaluated together (Forner-Cordero et al., 2012; Herbst et al., 2021).
Who is most commonly affected by lipedema?
Lipedema almost exclusively occurs in women. The onset often coincides with hormonal changes such as puberty, pregnancy, postpartum period, or menopause. This suggests that the disease may be related to hormones. However, it is not correct to view lipedema solely as a “hormonal disorder.” Many factors, such as genetic predisposition, connective tissue characteristics, microcirculation, inflammation, and lymphatic system loading, can play a role together (Child et al., 2010; Herbst et al., 2021).
Family history is important here. Many patients report similar leg structure in their mother, aunt, or sister. This similarity is sometimes described as “family-type hips.” Not every familial leg thickness is lipedema; however, if pain, bruising, and sensitivity accompany it, it should be evaluated.
“Why are my legs thicker compared to my upper body?”
This question is one of the most frequently asked by patients with lipedema. In lipedema, fat distribution is not equal throughout the body. Fat tissue becomes prominent mostly in the hips, thighs, knee area, and calves. In some patients, the arms are also affected.
The striking point here is the disproportion between the torso and legs. When the patient loses weight, their torso becomes thinner, but the legs do not respond at the same rate. This situation can create a feeling of “I am not making enough effort” in the patient. However, lipedema tissue can behave differently from classical fat accumulation. Diet and exercise support general metabolic health, weight control, edema, and movement capacity; however, the regional resistance of lipedema tissue should be communicated well to the patient.
For this reason, follow-up in lipedema should not be conducted solely through weight. Measurements of the waist, hips, thighs, knee circumference, and calves can provide more meaningful information. The fit of the patient's clothing, pain level, ease of walking, and feeling of swelling at the end of the day are also valuable in follow-up.
What are the symptoms of lipedema?
Lipedema is not just “thickness in the legs.” The findings suggesting the disease can be grouped under a few headings.
Pain and sensitivity
There may be pain or sensitivity to touch in lipedematous areas. Some patients describe this as “my legs feel like they are bruised,” “it hurts when touched,” or “it becomes very sensitive after a massage.” The pain is not of the same intensity in every patient. Some individuals may have mild sensitivity, while others may experience significant pain affecting daily life.
In the 2024 S2k guidelines, pain, pressure sensitivity, discomfort with touch, and a feeling of heaviness have been highlighted more in the definition of lipedema. This approach is important because it is not correct to diagnose lipedema solely by examining the thickness of the legs (Faerber et al., 2024).
Easy bruising
Patients with lipedema may bruise easily from minor bumps. Sometimes the patient may not even remember what they bumped into. This condition may be related to vascular fragility, changes in microcirculation, and connective tissue characteristics. Not every bruise indicates lipedema; bleeding disorders, medications, and other diseases should also be evaluated.
Symmetrical fat accumulation
Lipedema is usually bilateral and symmetrical. That is, both legs are affected similarly. An acute unilateral swelling in one leg suggests vascular obstruction, infection, or other emergencies rather than lipedema. This distinction should not be neglected for patient safety.
Feet are generally spared
In classic lipedema, the feet are often not visibly affected. Fat tissue proliferation appears to stop at the level of the ankle. This appearance is described as “cut-off at the ankle” or “cuff appearance” in some patients. In lymphoedema, the dorsum of the foot and the toes may be more frequently affected. Of course, as the condition progresses or in cases of lipo-lymphoedema, the picture may become complicated.
Difficulty in regional thinning despite diet
A patient with lipedema can lose weight. This point should not be misunderstood. A proper nutrition plan, exercise, sleep, management of insulin resistance, and control of inflammation can be beneficial for patients with lipedema. However, the lipedematous areas, especially around the legs and hips, may be more resistant to classical weight loss. Most patients struggle to make this distinction.
Therefore, the goal in treatment is not just to answer the question “how much weight did I lose?” Reducing pain, improving movement, changing measurements, decreasing the feeling of edema, and making the patient’s daily life easier are also important.
What causes lipedema?
There is no single cause of lipedema. Current knowledge suggests that the disease is multifactorial. Genetic predisposition, hormonal periods, changes in connective tissue, behavior of fat cells, microcirculation, and inflammation should be evaluated together.
Fat tissue is not merely an energy storage. It is an active tissue that communicates with hormones, the immune system, vascular structure, and the lymphatic system. In lipedema, the structure of this tissue and its relationship with surrounding tissues may change. Some studies have discussed nodular structure in fat tissue, a tendency for fibrosis (hardening), inflammatory signals, and disturbances in tissue fluid balance (Kruppa et al., 2020; Herbst et al., 2021).
The message that should be given to the patient is clear: Lipedema is not a lack of willpower or a simple cosmetic issue. However, this does not mean that “nothing can be done.” When proper nutrition, appropriate exercise, manual lymph drainage, compression, weight management, psychological support, and surgical options in necessary cases are addressed together, the patient's complaints can be reduced.
What are the stages of lipedema?
Lipedema stages are generally described according to the skin surface, the structure of adipose tissue, the formation of nodules, and shape changes. In older classifications, three stages were used, while in some clinical descriptions, a fourth stage includes lipo-lymphoedema. However, there is an important warning in new guidelines: Morphological stages, i.e., staging based on external appearance, do not solely indicate the severity of the disease. Factors such as pain, quality of life, movement capacity, and accompanying obesity should also be evaluated (Faerber et al., 2024).
Stage 1 lipedema
In stage 1, the skin surface is usually smooth. The patient may notice disproportionate thickness, sensitivity, a feeling of heaviness, or easy bruising in their legs. There may be no obvious disorder from the outside. This is why diagnosis can be overlooked in the early stages.
In this stage, patients often say, “My legs have always been thick, but they have become more painful in recent years.” Early detection is valuable; because lifestyle adjustments and conservative treatments can be more easily applied at this stage.
Stage 2 lipedema
In stage 2, the skin surface becomes more irregular. There may be small nodules, a waviness, and an orange peel-like appearance in the adipose tissue. Pain and sensitivity may increase. Changes in shape around the knee, thigh, and calf become more pronounced.
During this period, patients often report, “My cellulite has increased a lot,” “My legs have become bumpy,” “Even if I lose weight, the shape doesn’t change.” Confusion between cellulite and lipedema is frequent.
Stage 3 lipedema
In stage 3, fat tissue increase is more evident. Large lobules, sagging, and pronounced shape deformities in the knee and legs can be seen. Walking, climbing stairs, and standing for long periods may become difficult. In this stage, as movement decreases, weight gain and a feeling of edema may also be added to the picture.
The treatment plan in stage 3 lipedema should be more comprehensive. Nutrition regulation, exercise, manual lymph drainage, compression, and evaluation of accompanying venous or lymphatic problems are necessary.
Stage 4 or lipo-lymphoedema
In some classifications, stage 4 refers to the addition of lymphoedema on top of lipedema. Lymphoedema is a swelling condition that develops due to the accumulation of lymph fluid in tissues. As lipedema progresses or as factors like accompanying obesity, inactivity, and venous insufficiency increase, the lymphatic system may become more overloaded.
In this case, the dorsum of the foot may also swell, the edema may become more permanent, and the treatment approach changes. In such a situation, a physician's evaluation is essential.
What are the types of lipedema?
The types of lipedema are described based on the regions of the body affected by the disease. The type is different from the stage. While the stage describes the tissue appearance and progression level of the disease, the type describes the affected region.
In type 1, the hip and thigh areas are more pronounced. In type 2, the involvement extends from the thighs to the knees. In type 3, the area below the knee and the ankle is affected. In type 4, the arms are also included in the picture. In type 5, the calf area is more prominent.
Multiple regions can be affected in one patient. Therefore, the classification of types should be used not to label the patient but to make treatment planning and monitoring more organized.
How is lipedema differentiated from obesity?
Lipedema and obesity can coexist. Therefore, differentiation is sometimes not easy. Obesity is characterized by a general increase in fat tissue in the body. In lipedema, however, fat distribution is more regional, and there is usually a pronounced disproportion in the legs.
Indicators suggesting lipedema include: bilateral symmetrical leg thickness, pain on touch, easy bruising, relatively spared feet, significant disproportion between upper and lower body, and limited thinning in the legs despite weight loss.
The treatment of obesity is also important in patients with lipedema because excess weight can strain the lymphatic system, reduce mobility, and increase pain. However, telling the patient to “just lose weight” is often inadequate. The treatment plan for the patient with lipedema should be considered more broadly.
How is lipedema differentiated from lymphedema?
Lymphedema is swelling that develops due to the accumulation of lymph fluid in the tissue. It can generally start unilaterally and affect the dorsum of the foot and toes. Lipedema, on the other hand, is usually bilateral, features swollen painful fat tissue, and the feet are better preserved in the classic picture.
During the examination, a test called the Stemmer sign can be performed. The Stemmer sign is the inability to pinch and lift the skin over the base of the second toe, which can be assessed in favor of lymphedema. However, not every patient presents as textbook cases. Lipedema, obesity, venous insufficiency, and lymphedema can coexist in some patients. Therefore, diagnosis should not be reduced to a single finding.
How is the diagnosis of lipedema made?
The most important step in diagnosing lipedema is the patient's history. When did it start, did it increase during puberty or pregnancy, is there a similar body structure in the family, are pain and bruising accompanying symptoms, how do the legs respond to weight loss, does swelling increase throughout the day, and such questions guide the evaluation.
Physical examination evaluates fat distribution, symmetry, condition of the feet, skin surface, nodular structures, sensitivity, tendency to bruise, venous findings, and signs of lymphedema. In some patients, venous Doppler ultrasonography, evaluations of the lymphatic system, or imaging methods may be necessary. However, imaging is not a requirement for every patient. Diagnosis is often made through clinical evaluation (Peled and Kappos, 2016; Herbst et al., 2021).
The aim in the clinic is not merely to answer the question “is there lipedema?” The accompanying obesity, venous insufficiency, signs of lymphedema, hormonal issues, insulin resistance, thyroid diseases, movement capacity, and psychological burden of the patient should also be evaluated.
In which situations should a doctor be consulted earlier?
Lipedema generally follows a slow course. However, some symptoms may suggest more urgent conditions that differ from lipedema.
Sudden unilateral leg swelling, redness and increased temperature in the leg, severe newly occurring pain, shortness of breath, chest pain, fainting feelings, or fever indicate that it is not correct to wait. These findings may be associated with vascular obstruction, infection, or other serious conditions.
Even in patients suspected of having lipedema, newly developed sudden unilateral changes should be evaluated separately. Ignoring these findings by saying “I already have lipedema” is not safe.
What is the fundamental approach in the treatment of lipedema?
A single method is not sufficient for everyone in the treatment of lipedema. The treatment plan should be prepared according to the patient's stage, complaints, weight, accompanying diseases, lifestyle, and expectations.
In the conservative treatment approach, which is non-surgical, nutrition regulation, exercise, manual lymph drainage, compression, skin care, weight management, and psychological support are addressed together. Ketogenic or low-carbohydrate diets may provide benefits for some patients in terms of the sensation of edema, appetite control, and metabolic regulation; however, the same plan does not fit every patient. Protein adequacy, electrolyte balance, fiber intake, vitamin-mineral status, and sustainability should be taken into account.
The goal in exercise is not to push the patient but to stimulate the muscle pump and increase movement capacity. Water-based exercises, walking, low-impact resistance exercises, pilates, and appropriate stretching exercises can be planned according to the patient’s condition.
Manual lymph drainage and compression may help reduce complaints like pain, heaviness, and edema in some patients. However, compression products should be selected individually for the patient. An incorrect size, wrong pressure, or an uncomfortable product that the patient cannot use disrupts compliance with treatment.
Surgical treatment may come into play, especially in selected patients where the lipedema tissue is prominent, and pain and restriction of movement affect quality of life. Liposuction is one of the methods used in this area. However, the decision for surgery should be made by clearly discussing the patient's expectations and risks. Lipedema surgery should not be presented as a substitute for nutrition and lifestyle adjustments.
How can the most appropriate approach to lipedema be summarized?
The first step in understanding lipedema is to listen to the patient without blaming them. These patients often hear “eat less, walk more” for years. Of course, nutrition and movement are important. However, the issue in lipedema is not just that.
A more accurate approach is as follows: The patient's fat tissue distribution, pain, tendency to bruise, feeling of edema, movement capacity, metabolic status, and psychological burden should be evaluated together. Treatment should also be planned accordingly.
Early diagnosis allows the patient to understand themselves. Correct follow-up reduces unnecessary feelings of guilt. A realistic treatment plan restores the patient’s sense of control.
Does lipedema completely heal?
Lipedema is a chronic disease. It is not accurate to say “it will completely go away.” However, significant improvements can be achieved in pain, sensation of edema, movement restriction, and quality of life. Better results are obtained when nutrition, exercise, manual lymph drainage, compression, and surgical options in necessary cases are evaluated together.
Does lipedema prevent weight loss?
Lipedema does not completely block overall weight loss. The patient can lose weight. However, lipedematous areas, especially the legs and hips, may be more resistant to weight loss. For this reason, in follow-up, not only weight but also circumference measurements, pain level, and movement capacity are important.
Is lipedema seen in men?
It is quite rare. Lipedema predominantly occurs in women. If a similar picture is present in men, hormonal disorders, liver diseases, obesity, lymphedema, and other causes should be investigated.
Is MR or ultrasound necessary for the diagnosis of lipedema?
It is not a requirement for every patient. The diagnosis is mostly made through history and physical examination. However, if the picture is complicated or if venous insufficiency, lymphedema, or other diseases are suspected, imaging methods may be used.
Are lipedema and cellulite the same thing?
No. Cellulite is more related to the cosmetic appearance of subcutaneous tissue. In lipedema, pain, sensitivity, easy bruising, disproportionate increase of fat tissue, and functional impairment can be seen. The two conditions can be confused in appearance.
Does lipedema progress?
In some patients, symptoms may increase over time, while in others it may progress more slowly. Weight gain, inactivity, hormonal periods, venous problems, and lymphatic overload can affect the picture. New guidelines emphasize that lipedema should not be described as an inevitably progressive disease in every patient.
