Lymphoedema is a chronic swelling condition characterized by the abnormal buildup of lymph fluid, typically in the arms or legs. It occurs when the lymphatic system, which is part of the immune system, is damaged or unable to drain fluid properly.
read more about lymphoedema ...The causes of lymphatic damage are often related to cancer treatment, such as the removal of lymph nodes or radiation therapy. Other causes include infection or inherited defects in the lymphatic system structure.
Swelling develops in one limb or both, creating a sense of heaviness and tightness. The skin thickens and feels firm with reduced flexibility around joints. Pitting may appear early and give way to non-pitting swelling later. Recurrent skin infections and slow wound healing can occur. Elevation and compression reduce symptoms in many cases.
Management strategies focus on reducing swelling and preventing infection. Treatment involves complex decongestive therapy (CDT), which includes manual lymphatic drainage massage, compression bandaging, meticulous skin care, and exercise.
Lymphoedema does not directly impact vision. However, similar lymphatic drainage issues can occur around the eye, causing chronic eyelid swelling (periorbital oedema), often worse in the morning, which can interfere with visual tasks and comfort.
Diagnosis relies on a physical examination and imaging tests, such as lymphoscintigraphy, which maps the flow of lymph fluid. Measurement of the affected limb's volume is also used to assess the severity of the swelling.
No, lymphoedema is chronic and requires ongoing management, but the swelling can be effectively controlled.
The swelling often causes a feeling of heaviness and discomfort rather than sharp pain, though secondary infections can be painful.
No, it can be caused by congenital defects, infection, or trauma, though cancer treatment is a common trigger.
Seek medical care if a swollen limb suddenly becomes red, hot, or painful, as this indicates "Cellulitis," which is common in lymphoedema. Severe facial lymphoedema can cause eyelid swelling that interferes with vision, requiring specialized decongestive therapy.
