Why Compression Garments And What is the Goal of Compression Therapy in Lipedema?
1. Why Compression Garments?
There are many reasons to consider using compression garments. The underlying problem with all lymph disorder is problems circulating lymph back to the venous system. For individuals who have lipedema, lymphedema or lipo-lymphedema, compression garments are often used to assist the lymph circulation by increasing the pressure in the tissue propel lymph fluid through the body. Lymphedema causes excess fluid to become trapped in the extremities, especially on the legs, and the compression garments put pressure on the skin and veins, help them to clear lymph and decongest.
Besides improvement to lymphatic flow, there is some debate about compression garments’ benefits related to fat disorders, such as lipedema. Most people with lipedema( 脂肪水腫 ) the pain tenderness are worsened by swelling and activities such standing or having the leg or hand dependent that promote local swelling. Compression garments can help reduce pain and heaviness felt in the limbs from fat disorder such as lipedema by decreasing swelling in the fat and throughout the limb. Also compression potentially reduces the rate at which the fat cells grow and help to prevent fat disorders from progressing to more serous stages. In other words, compression can be one of the best treatments for lipo-lymphedema or fat causes by lymphatic diseases.
2. The Goal of Compression Therapy in Lipedema
The goal of compression therapy in lipedema is:
Compression has been shown to reduce discomfort, aching and limb heaviness as well as supporting the health of the tissue. Compression helps to streamline uneven or distorted limb shape and improve movement. Compression helps to reduce edema by reducing the interstitial fluid formation and encourage venous and lymphatic return in lipedema. (Hardy, 2016) All three goals are critical for the management of lipedema. Compression is the cornerstone on which all other treatments for lipedema are built upon as it is the only treatment that has been shown to benefit every patient with lipedema. Studies have shown medical grade graduated compression is the most universally applied effective treatment for reliving limb heaviness, tenderness and leg cramping and it should be the first line of treatment for lipedema as it is an extremely low risk and relatively low cost and readily available treatment. Compression with or without other lymphatic stimulating treatment are an effective first line of therapy for managing lobules, wrist and ankle cuffs that occur with lipedema.
3. Why is Compression Garments Needed in All Stages?
Lipedema is characterized by painful and swollen fat which accumulates disproportionately in the subcutaneous tissue. New studies have shown that all stages of lipedema show increased swelling in the lower extremities as measured by Bioimpedance. In a study published this year in the Journal of Lymphatic Research and Biology, Crescenzi, Donahue, and Herbst showed that compared to controls all stages of lipedema have increased extracellular water or swelling. (R. Crescenzi, 2019) Further, the study showed that the edema or extracellular water increased with each stage of lipedema. We know that extremity edema or lymphedema is associated with multiple inflammatory processes that are responsible for pain, tenderness and progressive fibrosis of the affected areas. All the Standard of Care [Dutch (Damstra, 2017), German, and British (Coppel, 2017)] Guidelines for the management of lipedema recommend the use of compression for patients with lipedema [Stage 2,3]. All of the care guidelines recommend a multidisciplinary approach to treatment involving lymphedema therapists teaching patients manual lymphatic drainage, proper fitting compression garments, and instruction on the proper application of the compression garments. Therefore, we conclude that compression is usually needed in stage 1 lipedema and always needed in stage 2 and 3 lipedema.
4. Compression Physiology and How Compression Works in Lipedema
Compression Physiology and How Compression Works in Lipedema
When considering the use of compression therapy in the management of lipedema, the basic principles should be understood. The law of Laplace is a mathematical formula that defines the relationship between pressure P, tension T, radius R, and garment layers N.
The law of Laplace
P relative to N T/R
P = pressure
N = number of layers T = tension applied = radius of limb
5. What Pressure Are Considered Medical Grade and Recommended for Lipedema?
Medical grade compression strength varies by the affected limb and the severity of the edema or fluid accumulation. An arm requires less compression to aid lymph flow because it is both smaller than a thigh and closer to the heart so under less gravitational pressure difference. In general, 18 -20 mmHg [Mercury] is considered medical-grade compression for the arm and 30 – 40 mmHg strength at the ankle is considered a medical-grade compression strength for the leg. These recommendations are based on studies primarily of primary lymphedema as this is the strength required to cause a significant improvement in lymphatic flow. (Mosti, 2019) The studies of compression garments show those [e.g. 30-40 mmHg ankle and 18-20 mmHg wrist] pressures give both optimal venous blood flow and lymphatic fluid clearance from the affected limbs.
Sometimes compromises are made, and lower 20-30 mmHg compression is used for individuals who have very mild edema or who are just starting to use compression garments or because of extreme sensitivity to the pressure of the compression. Ideally, the lower 20 -30 graduated compressions are used as a stepping-stone until the heavier compression can be tolerated because the evidence for this lower strength of graduated compression controlling interstitial fluid is much weaker and not as trustworthy.
While it is yet to be proven that proper compression can reduce the progression of the lipedema at this time, the recommended graduated 30-40mmHg pressures at the ankle have been shown to be effective at minimizing edema, reducing symptoms and halting the progression of the disease in closely related lipedema, veno-lymphedema, and other diseases that are known to cause secondary lymphedema and therefore 30-40 mmHg strength at the ankle must be the goal of compression therapy.
