Too high potassium in blood, what does this mean?

A potassium level that is too high or too low can be dangerous. Abnormal potassium levels may cause symptoms such as muscle cramps or weakness, nausea, diarrhea, frequent urination, dehydration, low blood pressure, confusion, irritability, paralysis, and changes in heart rhythm.

High blood potassium levels may be caused by damage or injury to the kidneys that prevents them from removing potassium from the blood normally.
High blood potassium levels can also be caused by conditions that release potassium from the body's cells into the blood. These conditions include severe burns, crushing injuries, heart attack, and diabetic ketoacidosis.
Excessive use of potassium supplements can also cause high levels of potassium in the blood.
Excess acid in the blood increases potassium levels by causing the potassium within the body's cells to eak?out of cells and into the blood.
Some medications, such as angiotensin-converting enzyme (ACE) inhibitors, can cause high potassium levels.
