Does Uremia Cause Hyperkalemia

Hyperkalemia is one of the most common complications of Uremia, but most patients have no idea on why Hyperkalemia appears in Uremia. I want to explain here.
In normal cases, the intake of potassium content by diet is far below the excretion capability of our kidneys, so the reasons for Hyperkalemia are mainly related with the decline in renal function.
Simply speaking, the reasons for Hyperkalemia caused by Uremia generally include three points.
1.Difficulty in Removing Potassium by Kidneys
In Uremia, the patients’ kidneys are mostly damaged and the renal function is
very weak, so most of the excessive potassium ions cannot be removed through kidneys, which leads to the accumulation of K+ in the body and eventually forms Hyperkalemia.
2.Diet or Medical Factors
Excessive intake of potassium-highly foods or overmuch medication-taken can both leads to the elevation of potassium concentration in the blood, besides this reason, eating too much fruits especially orange or its juices is another reason. And, some medicines are also responsible for Hyperkalemia.
3.Release of Potassium from Cells
In some conditions, such as acidosis, perisitent spasm, large amount of internal bleeding, or infections, organisms catabolism could be increased, so potassium ion will be transferred from intracellular parts to the extracellular parts.

Now, these three points are the main reason for Hyperkalemia in Uremia patients. Treatment for Hyperkalemia should be based on your specific conditions.
