Lymphedema is a condition in which, there is an increase in the size of the extremity (upper limbs, lower limbs) that is caused by partial or total obstruction of the lymphatic channels. In the beginning, this increase in size is due to lymph accumulation. With the passage of time, if left untreated, this accumulated lymph triggers an increase in the supporting tissues of the affected limbs. This, not only causes limb size to increase on a more permanent basis, but also reduces the oxygen availability to the tissues. This interferes with wound healing and provides a good environment for infection that may happen very frequently. Every such episode further increases the irreversible swelling.
