What is the name of the disease that causes low hemoglobin and high potassium in the blood ?

Hello Anon

Thank you for writing.

I'm not sure there is one specific disease that causes both of these conditions simultaneously but too much potassium is known as hypokalemia. Low hemoglobin can cause anemia but both of these conditions can also occur separately.
Both may be treated with diet and/or supplements.
Best,
Susan
