The lymphatic system
The lymphatic system forms part of the immune system. It is a system of vessels, organs and tissues that help the body maintain fluid balance, absorbing fats and protecting the body from infections. Part of its process is to collect excess fluid from tissues and returning it to the bloodstream.

What happens when your lymphatic system stops working?
When your lymphatic system stops working efficiently, it can lead to lymphoedema (chronic swelling of the tissues). Lymphoedema can be primary (born with) or secondary (due to damage). Primary lymphoedema is typically a hereditary condition, where people are born with an abnormality affecting the lymphatic system. This can present itself at any time of life. Secondary lymphoedema is caused by damage to the lymphatic system. This can be due to surgery (commonly cancer surgery where lymph nodes are removed), radiotherapy treatments (for cancer), trauma or tissue damage, infection (filariasis) or being sedentary. Lymphoedema can happen immediately after any of the above reasons; or not develop until months or years later.
