What are the common lack of potassium side effects?

The essential mineral potassium is an important tool in maintaining healthy muscle and strong nerve function. Potassium deficiency, or hypokalemia, is usually caused by dehydration or long-term use of laxatives and diuretics. The most common gastrointestinal side effect of potassium deficiency is constipation. Lack of potassium side effects that affect the cardiovascular system include low blood pressure and arrhythmia, an abnormally fast or slow heartbeat. The most common side effect of potassium deficiency in the muscular system is muscle cramps, mainly in the legs.

Although potassium deficiency is often caused by the overuse of laxatives and diuretics that rapidly remove fluids from the body, one of the most common side effects of potassium deficiency can be constipation. After long-term use of laxatives and diuretics, the body can become severely dehydrated as it tries to retain water and electrolytes, such as potassium. The normal physiological response is to draw water from the waste and cause severe constipation. Instead of increasing fluid intake to relieve constipation, many patients further increase their use of laxatives, compounding the problem. This situation can lead to intestinal obstruction in extreme cases.

One of the lack of potassium side effects on the cardiovascular system is low blood pressure. Low blood pressure related to hypokalemia is usually due to the use of diuretics or medications that increase urine output and cause loss of fluids and electrolytes, and decrease the volume of blood in the body. Low blood pressure is a physiological response to decrease blood volume because there is less blood to transport through the blood vessels.

Potassium is essential for muscle contraction and when potassium is in short supply within the body, performance can be affected by muscle contraction. Muscle cramps, predominantly in the legs, are usually the first muscle-related lack of potassium side effects that are felt. As hypokalemia becomes more pronounced, the lack of potassium begins to affect electrical conduction in the heart. Irregular electrical conductivity can cause fast or slow irregular heartbeats, known as arrhythmia.

In mild cases of hypokalemia, adding more potassium-rich foods will alleviate side effects. When hypokalemia is more severe, the typical treatment is to take potassium supplements or receive potassium intravenously. Sometimes dietary changes may allow lower doses of laxatives and diuretics, or diuretics can be used that help the body retain potassium, alleviating the side effects of potassium deficiency.
