Question: 1 / 400

What type of edema occurs primarily due to lymphatic transport issues?

Cardiac edema

Lipedema

Chronic venous insufficiency

Lymphedema

Lymphedema occurs primarily due to lymphatic transport issues, making it the correct response. This condition is characterized by the accumulation of lymphatic fluid in the interstitial spaces, resulting in swelling, typically in the arms or legs. It arises when the lymphatic system is unable to adequately transport lymph fluid, which can happen due to congenital defects, surgical removal of lymph nodes, radiation therapy, or infection.

Lymphedema is distinguished from other forms of edema by its specific association with dysfunction or impairment of the lymphatic system. Unlike cardiac edema, which is related to heart failure, or chronic venous insufficiency, which depends on problems with venous blood return, lymphedema is solely linked to lymphatic problems. Lipedema, while also causing swelling and largely affecting women, is characterized by the disproportionate accumulation of fat tissue and is not primarily a lymphatic issue. Thus, lymphedema is the only type of edema in this question that specifically results from problems with lymphatic transport.
