Is Lymphoedema contagious?

Lymphoedema is not contagious and cannot be spread from person to person through touch, bodily fluids, or any form of social contact. It is a chronic condition caused by the failure or obstruction of the lymphatic system, which leads to the accumulation of protein-rich fluid in the body's tissues.

Is there any risk of contagion when living with Lymphoedema?

There is absolutely no risk of contagion when living with, touching, or caring for someone with Lymphoedema. Because Lymphoedema is a mechanical or structural issue within the lymphatic vessels rather than an infectious disease, it poses no threat to family members, caregivers, or friends. The condition is entirely non-communicable.

What actually causes Lymphoedema?

Lymphoedema occurs when the lymphatic system is damaged or underdeveloped, preventing lymph fluid from draining properly. Clinicians categorize the condition into two primary types:

• Primary Lymphoedema: Caused by genetic mutations that affect the development of lymphatic vessels (present at birth or developing at puberty).


• Secondary Lymphoedema: Caused by damage to the lymphatic system, most commonly due to surgery (such as lymph node removal for cancer), radiation therapy, trauma, or chronic infections like filariasis.

Why does stigma exist surrounding Lymphoedema?

Stigma often arises from a lack of public awareness regarding the visible swelling associated with Lymphoedema. Because the swelling can be pronounced, individuals unfamiliar with the disease may mistakenly assume the limb appearance is due to an infection or a contagious skin condition. This misconception can lead to unnecessary social isolation for the 86 members of the DiseaseMaps community and others living with the condition.

Are there environmental triggers for Lymphoedema?

While Lymphoedema itself is not caused by environmental pathogens, certain environmental factors can exacerbate symptoms. Patients should be cautious of:

• Skin injuries or insect bites, which can trigger cellulitis (a bacterial infection of the skin) in the affected limb.


• Extreme heat, which causes vasodilation and increased fluid load.


• Inactivity, which slows the natural lymphatic pump mechanism.

Next steps

• Consult a certified lymphedema therapist (CLT) for manual lymphatic drainage and compression therapy.


• Join the DiseaseMaps community to connect with others who understand the reality of living with Lymphoedema.


• Maintain meticulous skin hygiene to prevent secondary infections.
