Cause 12. Prolonged Periods of Fasting or Starvation: Depleting the Body’s Potassium Stores
Prolonged periods of fasting or starvation can lead to low potassium levels as the body depletes its stores of essential nutrients, including potassium. When food intake is significantly reduced or nonexistent, the body begins to break down its own tissues for energy, releasing potassium into the bloodstream. This excess potassium is then excreted through the kidneys, leading to a decline in potassium levels.
Additionally, fasting or starvation can lead to muscle wasting, which can further contribute to hypokalemia as potassium is released from the breakdown of muscle tissue.
To prevent fasting or starvation-related hypokalemia, it’s essential to maintain a balanced diet that provides adequate amounts of potassium and other essential nutrients. If you’re considering fasting for religious, health, or weight loss reasons, consult with a healthcare professional or registered dietitian to develop a safe and effective plan that meets your nutritional needs.
