Lymphatic diseases

Lymphatic Diseases are a group of disorders that affect the lymphatic system, a part of the body's immune system that helps fight infection and disease. These diseases can be either congenital or acquired and can involve various parts of the lymphatic system including the lymph nodes, lymph vessels, and lymphatic organs.

Overview

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. It is primarily made up of lymphatic vessels, which are similar to the veins and capillaries of the circulatory system. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.

Lymphatic diseases can occur when the lymphatic system is not functioning properly. These diseases can be broadly categorized into three types: lymphedema, lymphadenopathy, and lymphoma.

Lymphedema

Lymphedema is a condition characterized by swelling in one or more extremities that results from impaired flow of the lymphatic system. The two types of lymphedema are primary and secondary. Primary lymphedema is a rare, inherited condition caused by problems with the development of lymph vessels in the body. Secondary lymphedema is far more common and causes include damage from cancer or cancer treatment, surgery, or infection.

Lymphadenopathy

Lymphadenopathy refers to disease of the lymph nodes, in which they are abnormal in size, number, or consistency. This is often a response to infection, inflammation, or malignancy. Lymphadenopathy can occur in just one area of the body, in which case it is localized, or it can be generalized, where it occurs in two or more areas.

Lymphoma

Lymphoma is a type of cancer that begins in the lymphatic system. The two main types are Hodgkin lymphoma and non-Hodgkin lymphoma. Lymphomas can start in any part of the body where lymph tissue is found.

Treatment

Treatment for lymphatic diseases depends on the specific disease, its severity, and the patient's overall health. Options may include medication, compression garments, manual lymph drainage, physical therapy, dietary changes, and in some cases, surgery.
