What causes lymphedema?

summary

There are many etiological categories of lymphedema. Generally, it is difficult to get good treatment by taking medicine. Taking medicine can only relieve the disease. Taking into account the etiology and clinical types, it is mainly divided into two categories: primary and secondary. Primary lymphedema is mostly caused by congenital dysplasia such as lymphangiectasia, valve insufficiency or absence. Among them, lymphodysplasia is very rare, common in congenital lymphedema. Next, I would like to share what causes lymphedema?. Hope to help you.

What causes lymphedema?

First, lymphedema is mostly caused by lymphatic obstruction. This edema is due to postnatal causes. Including: trauma, recurrent infection, malignant tumor and metastasis. In developed countries, the most common cause is malignant tumors, including those caused by cancer treatment. In developing countries, it is mainly due to secondary nematode infection or filariasis.

Second: the most common in China are secondary lymphedema, filariasis lymphedema, streptococcus infection lymphedema and upper limb lymphedema after radical mastectomy.

Third, the lymph is the tissue fluid in the intercellular space, which flows back into the vein through the lymphatic vessels. Lymphatic circulation is also one of the physiological and functional physical circulation. Congenital dysplasia of the lymphatic system or occlusion or destruction of the lymphatic system due to some reason results in the obstruction of the distal lymphatic return and the abnormal increase of interstitial lymph. If it occurs in the limbs, the affected limbs are thickened evenly. At first, the skin is smooth and soft, and the edema of the affected limbs can be significantly subsided after lifting.

matters needing attention

Infection increases inflammatory exudate, stimulates a large number of connective tissue proliferation, destroys more lymphatic vessels, aggravates the retention of lymph, increases the chance of secondary infection, and forms a vicious circle, resulting in increasing lymphedema.
