Hypokalemia means there is a lower-than-normal level of potassium in the blood. People who have severe hypokalemia might experience a breakdown of their muscle cells and have heart abnormalities. Hypokalemia can occur after a stomach flu or as a result of more serious medical conditions.
Kidney Disorders
People who have kidney disease might not have the ability to retain the potassium present in the body. Diseases including Cushing syndrome, Liddle syndrome and Fanconi syndrome might lead to hypokalemia.
Gastrointestinal Illness
Diarrhea and excessive vomiting can contribute to hypokalemia if the symptoms persist long term. During gastrointestinal illness, potassium is excreted from the body faster than normal, and levels can drop. People who have bulimia might be similarly affected.
Excessive Sweating
The National Institutes of Health report excessive sweating can be a cause of hypokalemia. Sweating can cause the body's electrolyte levels to become unbalanced.
Medication Use
Some medications can cause hypokalemia, including diuretics that promote urination. Antibiotics such as gentamicin and carbenicillin might also lower blood potassium levels.
Licorice Products
Licorice products that contain a substance called glycyrrhetinic acid can cause hypokalemia in some people. Licorice candy and herbal teas manufactured in the United States do not contain this ingredient, but items produced in other countries might contain the acid.
