Lipoedema

Understanding a little-known women's health condition

Lipedema is a chronic, often misdiagnosed condition that exclusively affects women. It manifests as an abnormal accumulation of painful fat in the legs, thighs, and hips, and sometimes the arms, while sparing the hands and feet. Unlike simple weight gain, this fat is resistant to diet and exercise.

How to recognize lipedema ?

Many women live with lipedema without knowing it. Here are the most common signs:

  • Symmetrical swelling of the legs, sometimes starting as early as puberty
  • Spontaneous pain or pain when pressure is applied
  • Unusual skin sensitivity
  • Easy and rapid bruising
  • A feeling of heavy legs, even at rest
  • Legs and sometimes arms that are disproportionate compared to the rest of the body

These symptoms may worsen or evolve during hormonal phases such as pregnancy, menopause, or periods of intense stress.

What are the causes ?

Although the exact causes of lipedema are not yet fully understood, scientific research and clinical experience highlight several triggering or aggravating factors. These elements do not act in isolation but often combine to promote the onset and progression of the disease.

1. Genetic predisposition

In more than 50% of cases, several affected women are found in the same family: mothers, sisters, aunts, etc. This suggests a hereditary transmission of lipedema, even if the responsible gene has not yet been clearly identified.

2. Hormonal influence

Hormonal imbalance, particularly related to estrogen, plays a central role in the development of lipedema. The disease often starts or worsens at key periods in a woman's hormonal life:

  • Puberty
  • Pregnancy
  • Postpartum
  • Menopause

This strong link with hormones explains why lipedema almost exclusively affects women and why it evolves over time if no management is implemented.

3. Associated circulatory disorders

Even if lipedema is not caused by venous or lymphatic disease, these pathologies can coexist and accentuate the symptoms:

  • Venous insufficiency (heavy legs, varicose veins)
  • Lymphedema (swelling due to poor circulation of lymph)
  • Capillary fragility (rapid appearance of bruises)

In advanced stages, the fatty mass can compress the lymphatic channels and lead to secondary lymphedema, making treatment more complex.

Lipedema Disease

Diagnostic

The diagnosis of lipedema relies primarily on a thorough clinical evaluation. This is a crucial step, as the disease is often confused with obesity, cellulite, or lymphedema. Misdiagnosis leads to years of medical wandering, unnecessary suffering, and ineffective treatments.

Specialized Clinical Examination

The first step in diagnosis involves visual observation and palpation of the affected areas. The doctor evaluates:

  • The distribution of volumes: legs, thighs, hips, arms – always sparing the feet and hands.
  • The symmetry of the limbs: an essential criterion of lipedema.
  • Sensitivity to pressure: marked pain upon palpation of fatty tissues.
  • The presence of frequent or spontaneous bruises (capillary fragility).
  • The condition of the skin: orange peel or nodular appearance in advanced stages.

The Stemmer's test is also performed: in lipedema, the skin on the top of the toes can be pinched (negative sign), unlike in lymphedema.

Additional Examinations

Even though the diagnosis is primarily clinical, certain examinations are useful to confirm lipedema or rule out other causes:

  • Venous Echo-Doppler: allows verification of the integrity of the venous network and detection of associated venous insufficiency (frequent).
  • MRI or tissue ultrasound: in some cases, to analyze the structure of fatty tissues.
  • Lymphoscintigraphy: to differentiate lipedema from lymphedema if suspicious swellings are present.
