What Causes Lymphedema in Feet: Symptoms & Treatment
What Causes Lymphedema in Feet: Symptoms & Treatment Lymphedema is a condition where swelling occurs due to a compromised lymphatic system. This system, responsible for draining fluid from tissues, can fail, leading to abnormal accumulation in the body. When this happens, it often affects the feet and other extremities.
There are two main types: primary and secondary. Primary lymphedema is genetic and rare, affecting about 1 in 100,000 Americans. Secondary lymphedema is more common and often results from treatments like surgery or radiation. Both types can lead to chronic swelling, lasting more than three months.
If left untreated, complications such as infection or cellulitis may arise. Rarely, it can increase the risk of certain cancers. Understanding the symptoms and seeking proper treatment is crucial for managing this condition effectively.
This guide will explore the causes, symptoms, and management strategies to help you better understand and address lymphedema.
Understanding Lymphedema in Feet
The lymphatic system plays a vital role in maintaining fluid balance in the body. It removes waste, supports immune function, and ensures proper circulation. When this system is compromised, fluid can accumulate, leading to swelling in the legs and feet.
What is Lymphedema?
Lymphedema occurs when the lymphatic vessels cannot drain fluid effectively. This results in persistent swelling, often in the lower extremities. Primary forms, like Milroy’s disease, appear in infancy, while others, such as Meige syndrome, develop during puberty or pregnancy. Secondary forms, accounting for 90% of cases, are often linked to surgery, radiation, or infections.
How Does Lymphedema Affect the Feet?
