Lymphedema

Category: General Science | Human Physiology | Public Health

UPSC Notes

Lymphedema is a chronic condition characterised by swelling caused by the accumulation of lymphatic fluid in tissues. It develops when the lymphatic system is damaged, obstructed or unable to transport lymph effectively.

It commonly affects the arms or legs but can involve other parts of the body.

Key Pointers

  • Body system involved: Lymphatic system.

  • Main mechanism: Impaired lymph drainage and fluid accumulation.

  • Primary lymphedema: Associated with developmental abnormalities of the lymphatic system.

  • Secondary lymphedema: Can result from surgery, radiation therapy, infection, injury or other damage.

  • Infectious cause: Lymphatic filariasis is an important cause in endemic regions.

  • Symptoms: Persistent swelling, heaviness, restricted movement and skin changes.

  • Management: Compression therapy, exercise, skin care and specialist-directed lymphatic treatment.

  • Public-health relevance: Prevention and treatment of filariasis can reduce disability in endemic communities.

UPSC focus: Human physiology, neglected tropical diseases, lymphatic filariasis and healthcare access.
