4 edema

Edema occurs because of damage to the lymphatic system which causes fluid retention and tissue swelling. It is usually categorized according to its severity. The WHO expert committee has divided edema into three types according to its severity. But other methods of categorizing edema do recognize 4 different stages of edema. The fourth stage is the most severe kind of edema with the lymph channels being completely blocked. As a result, the affected limbs are extremely huge and the condition is therefore also referred to as gigantic edema. It is also known as elephantiasis and it's a condition that is irreversible.
