Does chemotherapy affect potassium levels in your body?

Yes, chemotherapy can affect potassium levels in the body.

Chemotherapy drugs can damage the cells in the kidneys, which can lead to a decrease in potassium levels. This is because the kidneys are responsible for regulating the levels of electrolytes, such as potassium, in the body. When the kidneys are damaged, they cannot properly filter out potassium from the blood, which can lead to a build-up of potassium in the body. This can cause a condition called hyperkalemia.

On the other hand, other chemotherapy drugs can cause the body to lose potassium through the urine, which can lead to a decrease in potassium levels. This is because some chemotherapy drugs can affect the way the body absorbs and processes potassium. This can cause a condition called hypokalemia.

Therefore, it is important for people undergoing chemotherapy to have their potassium levels monitored regularly to ensure that they remain within a normal range. If necessary, potassium supplements or other medications may be prescribed to help maintain potassium levels.
