Leg swelling occurs because of an abnormal accumulation of fluid in the tissues in your lower extremities, which COULD be a sign of kidney failure.
The medical term (as I understand it) for leg swelling, from excessive fluid in the tissues, is edema.
I will say though, that there are many, many other causes of leg swelling besides kidney failure, so don't take my word for it (go seek professional advice).
I just looked this up, and they list the below as other possibilities for fluid retention in the lower extremities:
***
~Baker Cysts
~Cellulitis
~Cirrhosis (Liver)
~Congestive Heart Failure
~Eosinophilic Fasciitis
~Phlebitis
~Scleroderma
~Idiopathic Edema (Swelling of Unknown Cause, typically in women)
~Leg Vein Obstruction
~Medications that you are taking
~Nephrotic Syndrome
~Phlebitis
~Salt Retention
~Trauma Injury (Contusion, Hematoma)
***
I hope that helps you a little in self-diagnosing.
All the best.
there are many factors that could cause Edema (swelling on the body).
I agree with el_em_en_oh, seek medical advice in this matter A.S.A.P..
While you do that, cut down sodium in your diet and try to do a little more walking if possible, this will get the fluid moving or circulating and going into the cardiovascular vein which will help remove it from your system.
Take care!!
