Low potassium could potentially cause severe foot pain. When the body is deficient in this mineral, you’re far more likely to suffer muscle cramps. If this cramp is isolated to the foot, it may translate into pain. But cramps, and any associated pain, often result from severe deficits in this mineral. You’re not likely to experience any symptoms until your potassium level dips fairly low, leading to something known as hypokalemia.
Potassium
Potassium is essential to the proper function of muscles. Like any other electrolyte in the body, this mineral helps carry electrical impulses. If levels drop too low, the impulses may misfire, leading to sudden spasms that may cause the affected muscle to contract violently. When this occurs in one or more of the muscles in your foot, it can cause a cramp that may be painful.
Development
Dietary deficiencies in this mineral aren’t usually the cause of this condition. Instead, your potassium levels drop as a result of a health condition or medication. Kidney failure, diabetic ketoacidosis, Cushing syndrome and aldosteronism can all contribute to drops in potassium levels, but taking diuretics, laxatives, penicillin and other antibiotics can all have an impact on potassium levels. You’re also more likely to develop hypokalemia from prolonged bouts of vomiting or diarrhea. Even sweating can reduce potassium levels to the point of a deficit.
Treatment
A potassium supplement can often treat mild cases of hypokalemia. Because you’re dealing with low levels of potassium that cause symptoms, supplementation may not be enough to improve your condition. In this situation, medical intervention may be necessary. Your doctor may recommend intravenous potassium supplementation. If left untreated, your condition may worsen, sometimes to the point of heart rhythm problems. If muscle cramps are also accompanied by fatigue, weakness and constipation, talk to your doctor. This could be an indication of a severe depletion in potassium levels.
Prevention
Although dietary deficits are rarely the cause of hypokalemia, you can prevent low potassium by increasing your intake of foods high in this mineral. Eat plenty of bananas, bran, carrots, oranges, spinach, tomatoes, kiwi, lima beans, peas and other legumes. You can also increase your intake with peanut butter, seaweed and molasses.
