Lymphedema is a chronic disease characterized by excessive accumulation of interstitial fluid in certain areas of the body, most often in the extremities. This occurs as a result of insufficiency of the lymphatic system, which complicates the outflow of lymph. Lymphedema can be both primary and secondary. Primary lymphedema is associated with genetic disorders in the development of lymphatic vessels, while the secondary form occurs as a result of damage to the lymphatic system, for example, after surgery, infection or tumor processes. Symptoms of the disease include swelling, heaviness in the limbs and increased susceptibility to infections. Lymphedema requires a comprehensive approach to diagnosis and treatment, as various complications are possible, including infectious manifestations and decreased functional capacity of the limbs.
History of the disease and interesting historical facts
The history of lymphedema goes back centuries. The first mentions of this disease are found in ancient texts and medicines, in particular in Egyptian literature, where there are images of people with signs of swelling of the extremities. In the 19th century, the Swedish physician Axel von Distens described lymphedema in more detail, noting its connection with diseases of the lymphatic system. However, a real understanding of the pathophysiology of this condition began to develop only in the early 20th century, when scientists began to study the structure of the lymphatic vessels and their functions. Since the 1940s, attention to lymphedema has increased with the development of oncological surgeries, when doctors saw that many patients after the removal of lymph nodes were faced with this condition.
Epidemiology
The epidemiology of lymphedema varies by region and population. According to the World Health Organization, primary lymphedema occurs in 1 in 6,000 newborns, while secondary lymphedema may occur in 10-30% patients after cancer surgery. In countries with a high level of medicine, the incidence of lymphedema can reach 20% among patients who have undergone treatment for breast cancer. In addition, lymphedema is a common complication in patients with helminthic infections in tropical countries, such as elephantiasis, where damage to the lymphatic system leads to massive edema.
Genetic predisposition to this disease
Genetic predisposition to lymphedema is multifaceted. Some genes, such as FOXC2, VEGFR3, and FLT4, are associated with lymphatic vessel development and function. Mutations in these genes can lead to primary lymphedema, which is classified into different types. Particular attention is paid to the disruption of lymphatic vessel development, which can be inherited in an autosomal dominant manner. It is important to note that many cases remain unexplained, and further study of genetic markers and mechanisms of development of underlying disorders of the lymphatic system is required.
Risk factors for the development of this disease
Risk factors that contribute to the development of lymphedema can be divided into several groups:
- Surgical interventions on the lymph nodes, such as lymphadenectomy, especially when treating cancer.
- Soft tissue injuries that may compromise the integrity of the lymphatic system.
- Infectious diseases such as filariasis leading to lymphatic lesions.
- Oncological diseases that are accompanied by metastases to the lymph nodes.
- The effect of radiation on tissues, which can lead to fibrosis and impaired lymph flow.
These factors significantly increase the risk of developing lymphedema, requiring health care providers to pay special attention to high-risk patients.
Diagnosis of this disease
The main symptoms of lymphedema include:
- Swelling that has a “soft” consistency and may increase throughout the day.
- An increase in the volume of the limbs, visually noticeable in comparison with other limbs.
- A feeling of heaviness, discomfort or pain in the area of swelling.
- Unusual susceptibility to infections.
Laboratory tests are also carried out for diagnostic purposes, including:
- General blood test to exclude infectious processes.
- Lymphography and ultrasound of the lymphatic vessels to assess their condition.
- MRI and CT to determine the extent of damage and exclude tumors.
Differential diagnosis must be made with other causes of edema, such as venous insufficiency, thrombophlebitis, allergic reactions.
Treatment
Treatment of lymphedema should be comprehensive and multi-stage. The main approaches to treatment include:
- Conservative measures: compression therapy, physiotherapy and special exercises to improve lymph flow.
- Pharmacological treatment: use of pharmaceutical products to improve microcirculation and reduce swelling.
- Surgical techniques including bypass operations and lymphatic vessel transplantation.
- New methods such as lymphatic stimulation and lymphatic drainage massage.
Each method requires an individual approach depending on the stage of the disease and general information about the patient’s condition.
List of medications used to treat this disease
The following groups of drugs can be used in the treatment of lymphedema:
- Pharmacological agents: diuretics that improve lymph flow (eg, furosemide).
- Pharmaceutical preparations containing active substances to improve microcirculation (eg diosmin).
- Immunostimulants and substances that improve tissue regeneration (eg, pentoxifylline).
These drugs can be prescribed by cerebrologists and lymphologists depending on the individual clinical situation.
Disease monitoring
Monitoring the course of lymphedema includes regular examinations, measurements of limb volume and weight, and monitoring of the level of inflammatory processes. The prognosis of the disease depends on its stage, quality and timeliness of treatment. Possible complications include recurrent infection, lymphangitis, and the development of fibrosis. It is important to conduct regular monitoring after the main course of treatment in order to promptly respond to changes in the condition.
Age-related features of the disease
Lymphedema can occur at different ages, but its manifestations may vary. In newborns and children, primary lymphedema is often associated with genetic predispositions. In older people, the disease is often associated with oncological processes and previous surgical interventions. It is important to note that in children, lymphedema may proceed more favorably, while in older patients it can quickly lead to significant functional losses.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends that patients with lymphedema pay attention to the following points:
- Perform compression therapy regularly to prevent the development of edema.
- Physical activity and specific exercises will help improve lymph flow.
- It is important to monitor the condition of your skin as it may be vulnerable to infections.
- Do not neglect medical supervision and regular check-ups with specialists.
The doctor also advises avoiding factors that contribute to the severity of the disease and raising awareness about lymphedema.
