Low potassium levels, also known as hypokalemia, can be caused by a variety of factors. Some of the most common causes include:

• Excessive loss of potassium through the digestive tract due to vomiting, diarrhea, or laxative use.
• Certain medications, such as diuretics (water pills) and some antibiotics.
• Adrenal gland disorders.
• Eating disorders, such as bulimia nervosa.
• Hyperaldosteronism.
• Laxative overuse.
• Low magnesium levels.
• Sweating.

Potassium is an essential mineral that is needed for cells, muscles, and nerves to function properly. Low levels of potassium can cause a range of symptoms, including muscle weakness, cramping, and abnormal heart rhythms. If you are experiencing symptoms of low potassium, it is important to speak with a healthcare provider to determine the underlying cause and receive appropriate treatment.
