What does the type of lipedema mean?
The type of lipedema describes which areas of the body are affected by the disease. This classification is used to see how the increase in fat mass is distributed at the level of the hips, thighs, knees, calves, ankles, or arms.
Patients generally first ask: "What stage am I at?" This is an understandable question. But the type is just as important as the stage. The stage describes the changes in skin and subcutaneous tissues. The type indicates the affected area. One describes the appearance of the tissues, while the other describes where lipedema manifests in the body.
In the clinic, this distinction is useful. Which areas need to be measured, which area the compression product will cover, which exercises might challenge the patient, and where the patient experiences the most difficulties in daily life are more clearly visible.
The general definition of lipedema, its symptoms, and the diagnostic process can be found in the main guide What is lipedema? Signs, stages, and diagnostic guide is the main connection point of this article.
"Does my type of lipedema indicate the severity of my disease?"
No. The type of lipedema does not, by itself, show the severity of the disease. The terms type 1, type 2, or type 3 do not mean "lighter" or "heavier." They only describe the affected area.
For example, in type 1 lipedema, the hip and buttock region is more defined. In type 3 lipedema, the involvement may extend down to the ankle. Yet, pain, tenderness, frequent bruising, movement restrictions, and quality of life vary from patient to patient.
That’s why telling the patient just "your type is this" is not sufficient. Is there pain? Is there a feeling of swelling at the end of the day? Are there frequent bruises? How does one react to weight loss? Is the bridge of the foot swollen? Are there signs of venous insufficiency? All these elements need to be assessed together.
The S2k 2024 lipedema guide emphasizes that the diagnosis and assessment of the severity of lipedema should not be reduced to appearance alone. The patient's pain, functional status, associated diseases, and quality of life should also be taken into account (Faerber et al., 2024 [2]).
What is the difference between the type of lipedema and the stage of lipedema?
These two concepts are often confused. They can be simply distinguished as follows:
The type of lipedema describes which areas are affected. Hip, thigh, below the knee, arm, calf?
The stage of lipedema describes the appearance of the skin and subcutaneous tissues. Is the skin smooth, wavy, with nodules, or are there smaller lobules of tissue present?
For example, a patient may have type 2 lipedema and be at stage 1. Another patient may have type 3 lipedema and show skin irregularity at stage 2. Thus, type and stage should be noted separately.
We have addressed the topic of stage in a separate article. For those who wish to read in detail, the stages of lipedema
will be complementary.
Type 1 lipedema: involvement of the hips and buttocks
In type 1 lipedema, the increase in fat mass is more pronounced around the hips and buttocks. The patient notices that their waist is wider compared to their upper body. They may have difficulty choosing pants and skirts, need to take larger sizes for the lower body, and apparent fullness may be observed in the hip area.
This type is sometimes considered "the body shape" for a long time. If the patient does not describe pain and tenderness, a distinction must be made between lipedema and lipohypertrophy. Lipohypertrophy is the disproportionate increase in fat mass that occurs without pain. In lipedema, pain, tenderness to touch, frequent bruising, and a feeling of heaviness may accompany the presentation (Herbst et al., 2021 [4]; Faerber et al., 2024 [2]).
In the early stage of type 1, the lower part of the legs may be less affected. Over time, the condition can extend to the thighs, around the knees, or to the calf region. It is not established that this occurs in all patients. That’s why regular follow-up is important.
Type 2 lipedema: involvement from the hips to the knees
In type 2 lipedema, the involvement extends from the hips and buttocks to the thighs, often to the contour of the knees. Fullness in the knee area may trouble the patient. Some patients mainly complain of an increase in volume inside the knees and on the inner thigh.
In this type, the upper parts of the legs are more distinctly affected. The friction of the inner thighs, discomfort during long walks, the inability to wear tight pants, and the feeling of heaviness in the legs when standing up or sitting down are often reported.
The increase in fat mass around the knees can sometimes affect movement. The patient may say that they have difficulty climbing stairs or squatting. Here, the problem is not only the increase in fat mass; mechanical load, muscle strength, joint health, and movement habits also contribute to the situation.
In type 2 lipedema, the exercise plan should be established without putting the patient at risk. The goal is not to injure the leg, but to stimulate the muscle pump and preserve mobility. Aquatic exercises, low-impact walking, controlled resistance exercises, and stretching may be evaluated according to the patient's condition.
Type 3 lipedema: involvement from the hips to the ankle
In type 3 lipedema, the increase in fat mass includes the hips, thighs, contour of the knees, and calves. The involvement may extend down to the ankle. In the classic presentation, the feet are relatively spared. This can create a "cut-off" appearance around the ankle. Patients sometimes describe this by saying "my leg suddenly stops at the ankle."
This appearance can be indicative of lipedema. However, on its own, it does not allow for a diagnosis. Since venous insufficiency, obesity, lymph edema, and orthopedic problems can also affect the shape of the legs.
In type 3 lipedema, the patient's complaints may be more widespread. Simultaneous involvement of the thighs, knees, and calves may decrease walking comfort. By the end of the day, a feeling of heaviness, fullness in the legs, difficulties in choosing clothing, and sensitivity after exercise may be observed.
Here, the condition of the feet should be evaluated carefully. In classic lipedema, the top of the foot is generally spared. If there is obvious swelling at the top of the foot, fullness of the toes, or permanent edema, an assessment from the perspective of lymph edema or lipo-lymphedema should also be considered.
Type 4 lipedema: lipedema in the arms
In type 4 lipedema, the arms are affected. This condition may manifest alone but is more often associated with involvement of the legs. Disproportionate increase of fat mass in the upper arm region, tenderness to touch, frequent bruising, and difficulties in choosing clothing can be observed.
Lipedema in the arm can sometimes go unnoticed by the patient. Because the patient primarily focuses on their legs. However, assessment of the arms should also be conducted during examination. Particularly, if there is obvious fullness, tenderness, and symmetric involvement in the area of the upper arms, the possibility of lipedema in the arms should be considered.
If the arms are affected, the choice of compression must be made with more caution. Not every patient tolerates arm compression easily. Daily life, work, heat, skin sensitivity, and duration of use need to be taken into account.
The presence of lipedema in the arms does not necessarily mean that the disease is very advanced. This area is also a manifestation area. The treatment plan is shaped according to the patient's complaints.
Type 5 lipedema: primarily affecting the calves
In type 5 lipedema, the calf region is more pronounced. Disproportionate thickening of the lower leg, fullness in the calves, and an increase in volume extending towards the ankle, and sometimes a clear transition at the ankle may be observed.
This type can sometimes mix with venous insufficiency or lymph edema in certain patients. Because swelling of the lower parts of the legs is a common complaint in the population. Saying that every patient with heaviness and thickness in the calves has lipedema is not correct.
During examination, pain, tenderness, frequent bruising, symmetry, condition of the top of the foot, skin changes, and venous signs must be evaluated together. If there are varicose veins, itching, color changes, marked edema at the end of the day, or swelling at the back of the foot, an evaluation of the venous and lymphatic systems becomes even more important.
The choice of compression in type 5 lipedema also requires special attention. In patients with a marked transition between the calves and the ankle, standard products may be uncomfortable. A poorly fitting product can lead the patient to completely avoid compression.
Can a patient have multiple types of lipedema?
Yes. Lipedema does not always correspond to a single type as described in books. A patient may have both leg and arm involvement. Another patient may have simultaneous involvement of the hips, thighs, and calves. Over time, the areas of involvement may change.
That’s why the classification into types should not be used to confine the patient into a narrow framework. Rather, it should be considered as a clinical harness. Which areas are affected? Which areas are painful? Where are there bruises? What measurement points will we monitor? Which area should the compression cover? What exercises may be challenging?
The answers to these questions make the classification into types practical.
"My legs are thick, but my feet are normal, what does that mean?"
This observation is striking in relation to lipedema. In classic lipedema, the feet are often spared. The increase in fat mass seems to stop at the ankle. That’s why a patient may say they have visible thickening of their legs, all while not having changed their shoe size, with no visible deformity on the top of the foot.
It is difficult for the patient to make this distinction alone. Because in some individuals, obesity, venous insufficiency, or lymphatic overload may play a role. If swelling appears at the top of the foot, or if there is fullness of the toes or permanent edema, an evaluation for lymph edema should be considered.
We will detail the difference between lipedema and lymphedema in a separate article. For now, it will suffice to say this: the preservation of the feet is an indicator in favor of lipedema, but does not diagnose it on its own.
Do the types of lipedema change the treatment plan?
Yes, they can. Because follow-up, compression, exercises, and manual lymphatic drainage may differ depending on the affected area.
In the case of involvement of the hips and buttocks, the measurement points differ. In the case of involvement around the knees and thighs, movement restrictions are questioned more often. In the case of predominant involvement at the calves, the distinction between venous insufficiency and lymph edema is made with more attention. If the arms are affected, compression of the upper limbs, shoulder movements, and daily usage habits are evaluated.
Once again, treatment is not reduced to a single aspect. Nutrition, exercise, manual lymphatic drainage, compression, weight management, sleep, stress, and possibly surgical options should be considered together. The classification of types helps to personalize this plan.
The best approach in the clinic is as follows: simultaneously observe the patient's type, stage, and burden of symptoms. A treatment plan should not be made solely by looking at a picture of the legs.
In which cases should other diseases be looked for?
Some manifestations in a patient suspected of lipedema may suggest other diseases. If there is sudden unilateral swelling, redness, an increase in temperature, intense onset pain, tenderness in the calves, dyspnea, or chest pain, an emergency evaluation is necessary.
There are also signs that develop slowly but should nevertheless be taken seriously. Marked swelling at the top of the foot, fullness of the toes, skin color changes, varicose veins, itching, frequent infections, open wounds, or rapidly increasing edema should be evaluated for lymph edema, venous insufficiency, and other vascular problems.
The diagnosis of lipedema does not mean that other diseases are ruled out. A good evaluation of lipedema often begins with this correct distinction.
What does a patient gain from knowing the types of lipedema?
Knowing the type of lipedema helps the patient better understand their own body. They see more clearly where they need to be monitored, which areas are more sensitive, which movements may be difficult during exercises, and how to choose the compression plan.
This information is not used to frighten the patient, but to manage the process more regularly. A remark like "I am type 3, my condition is very bad" is not correct. Type 3 only indicates that the involvement extends down to the ankle. The burden of disease is determined by pain, mobility, edema, associated diseases, and impact on daily life.
Following lipedema is somewhat like creating a map. First, we see which areas are affected. Then we monitor complaints, measurements, and responses to treatment in those areas. Thus, the classification into types does not label the patient; it makes treatment more understandable.
Frequently Asked Questions
Question: How many types of lipedema are there?
Answer: Lipedema is generally described in five types according to the affected area. Type 1 concerns the region of the hips and buttocks, type 2 concerns the area between the hips and knees, type 3 concerns the area between the hips and ankles, type 4 concerns the arms, and type 5 primarily concerns the calves.
Question: Does the type of lipedema indicate the stage of the disease?
Answer: No. The type describes the affected area, while the stage indicates changes in the skin and subcutaneous tissues. These two classifications should be evaluated separately.
Question: Can there be lipedema in the arms?
Answer: Yes, there can be lipedema in the arms. It generally accompanies involvement of the legs. Symmetric increase in fat mass, tenderness, and frequent bruising can be observed in the upper arms. However, it cannot be said that there is lipedema in every patient with arm thickness; an examination is necessary.
Question: Is the absence of involvement of the feet important for lipedema?
Answer: Yes, in classic lipedema, the feet are generally spared. The increase in fat mass seems to stop at the height of the ankle. However, if there is swelling at the top of the foot or fullness of the toes, an evaluation for lymph edema or lipo-lymphedema should be considered.
Question: Can the type of lipedema change over time?
Answer: In some patients, the area of involvement may expand over time. The picture may start with the hips and thighs and then progress to the calf region or may also affect the arms. This does not happen in the same way for all patients. Regular follow-up helps to detect changes earlier.
Question: Does the treatment change according to the type of lipedema?
Answer: The fundamental principles of treatment are similar; however, the application may vary. Measurement points, choice of compression, manual lymphatic drainage plan, and organization of exercise may differ based on the affected area.
