2. Pitting edema
Pitting edema occurs because the excess lymphatic fluid is not draining properly from the affected area. This fluid buildup creates increased pressure within the tissues, causing them to become more compressible. When pressure is applied, it displaces the excess fluid, resulting in a temporary pit. However, because the lymphatic system is compromised, the fluid returns to the area relatively quickly once the pressure is released.
The presence of pitting edema is an important diagnostic feature for healthcare professionals when evaluating the possibility of lymphedema. The depth and duration of pitting can help determine the severity of the condition. Healthcare providers use this information to plan appropriate treatment strategies and monitor progress.
