What Are Common Symptoms of Low Potassium?

Weakness, fatigue, constipation and muscle cramps are common symptoms of low potassium levels, according to Mayo Clinic. A complication called arrhythmia or an abnormal heart rhythm can occur when a person's potassium level drops too low. Drops in a person's potassium level can be a result of an illness or diuretics, a type of medication that is often used in high blood pressure treatments.

Hypokalemia occurs when an individual's potassium levels drop too low, according to Healthline. This condition is a result of releasing too much potassium through bowel movements, sweat or urine. Possible complications of the disorder include muscle twitches, mineral deficiencies, low blood pressure, and a loss of muscle control. Other symptoms associated with hypokalemia include excessive urination and a loss of appetite.

A small drop in potassium levels can cause mild symptoms, such as numbness, tingling, muscle spasms or palpitations, explains the University of Maryland Medical Center. A slight drop sometimes does not result in any symptoms at all. A larger drop in a person's potassium level can slow down his heartbeat and lead to feeling faint or dizzy. If the potassium level drops further, it can eventually stop a person's heart. An excess of thyroid hormones in the blood stream can result in a severe condition called thyrotoxic periodic paralysis.
