Symptoms of Low Potassium Chloride

• According to Oregon State University, potassium is an essential electrolyte and mineral in the body. Potassium chloride is a chemical compound that contains both potassium and chloride salts; this combination is common in many dietary supplements intended to correct potassium deficiency. Low levels of potassium chloride cause muscle weakness and fatigue. The medical term for potassium deficiency is hypokalemia.
  
  

Heart Problems

• According to the Mayo Clinic, potassium chloride is essential for heart and nerve function. The heart needs potassium to beat properly. Low potassium levels can lead to an abnormal heart rhythm and high blood pressure. Potassium deficiencies are often a result of poor diet. Foods such as bananas, meat and dark green leafy vegetables replenish potassium in the body. Potassium chloride supplements are also advised for people with very low potassium levels.
  
  

Muscle Cramps and Weakness

• According to the University of Maryland Medical Center, a potassium deficiency can cause muscle cramps and weakness. Potassium chloride and other forms of potassium help to maintain healthy nerves and muscle fibers. People who are deficient may wake up at night with leg cramps and experience weakness when walking.
  
  

Fatigue

• Another sign of a low potassium chloride level is fatigue. Because low potassium is related to changes in metabolism, the muscles are not getting enough nourishment to help move a person through his or her daily tasks and the person often feels tired.
