On the other hand, dehydration can temporarily make veins more noticeable. When the body loses fluids, the volume of plasma in the blood decreases and the veins become more prominent.
However, visible veins alone are not evidence of kidney damage .
When can veins be linked to kidney disease?
There are several specific medical situations where veins may look different in people with kidney problems.
Dialysis and varicose veins in the arm
In advanced kidney failure, known as end-stage renal disease , some patients require dialysis.
To make treatment possible, doctors often create an arteriovenous fistula in the arm. This is a surgical procedure in which an artery and a vein are connected to provide stable access for the dialysis machine.
After such a procedure, the veins may become:
more visible
thicker
slightly convex
However, this is a result of medical treatment , not a symptom of the disease itself.
When should you seek medical advice?
Instead of focusing only on the visibility of veins, it is more important to pay attention to other warning signs such as:
persistent swelling in the hands, ankles, or around the eyes
significant changes in the amount of urine
foamy urine
