Condition: Hypopotassemia

Hypopotassemia is a deficiency in the mineral potassium. Also called hypokalemia, hypopotassemia can be diagnosed by a blood test, which shows low levels of potassium in the bloodstream. The body needs potassium to work correctly, and very low levels of potassium in the blood can cause serious complications and may be life-threatening. Symptoms of hypopotassemia can include fatigue, weakness or spasms in the muscles, constipation, and even paralysis. Potassium is found in a number of foods, particularly bananas and other fruits, legumes, and peanut butter. Hypopotassemia may be caused by kidney problems, loss of bodily fluids through diarrhea, vomiting or heavy sweating.
