Symptoms of Low Potassium Levels
- Potassium is a vital element in the body. Not only do the muscles require potassium to contract, but the heart also needs it to beat properly and regulate blood pressure. A low potassium level can create a chaotic array of symptoms that are often mild but sometimes vague. Because potassium is responsible for muscle function, a lack of it will cause weakness, tiredness and cramping in the legs or arms. The weakness can occasionally become severe enough to prevent the movement of limbs, much like paralysis. These symptoms may also be accompanied by tingling or numbness in the limbs.
- When potassium levels are low, the kidneys are less able to concentrate urine in the body. This often results in passing large amounts of urine. A person may also feel exceedingly thirsty much of the time and may experience nausea, vomiting, abdominal cramping, bloating and constipation. These symptoms are especially common if the low potassium levels have been caused by diarrhea or an overuse of diuretics or laxatives.
- Because of the role it plays in maintaining normal heart function, low levels of potassium will often result in fainting due to low blood pressure. In very serious cases, these low potassium levels may cause heart palpitations and irregular heart rhythms.
- In some cases, it has been reported that patients with low potassium levels experience some type of psychological disturbance. Such instances may include depression, delirium, confusion and even hallucinations.
