“What happens if potassium is too low?”

It really depends on how low and for how long, but my personal experience with patients who have low potassium is heart arrhythmias, muscle weakness, and fatigue.

Thank you for your question. Potassium is one of the electrolytes needed by the body to maintain nerve, cell, and brain function. Low potassium levels can have many causes. However, it usually results from vomiting, diarrhea, use of diuretics, and adrenal gland dysfunction. When the body loses too much potassium, muscle cramping, muscle weakness, muscle twitching, and irregular heart beats can occur. The most reliable way to check if you're low on potassium is to get a blood test. If the test shows a deficiency, you can increase your levels by consuming foods high in potassium and taking a supplement. Your doctor will advise you further.
