Potassium DeficiencySevere potassium deficiency leads to a low potassium level in the blood, called hypokalemia. But a potassium deficiency is rare in healthy people. However, certain conditions can cause the body to lose significant amounts of potassium. Examples of these conditions include:
- Excessive diarrhea or laxative use
- Kidney problems
- Use of certain blood pressure medications
- Continuous poor food intake—may occur as a result of alcohol use disorder, anorexia nervosa, bulimia, or very low calorie diets
