10 Kidney Failure Symptoms
Symptom #6: Edema
Edema occurs when there is abnormal and excessive fluid accumulation in the interstitium. Clinically, edema appears as swelling. Pitting edema occurs when there is cutaneous edema. When pressure is applied to a localized area, it results in an indentation. This is more commonly seen at the peripheries.
It can be caused by pregnancy and other systemic diseases such as heart failure, liver failure, or kidney failure. It can also be seen in local conditions such as thrombophlebitis, dermatitis, varicose veins, and insect bites. Edema occurs in kidney failure patients due to failure of the kidneys to remove excessive fluid from the body.
