What Are the Dangers of Potassium Levels Being Too Low?

Potassium is an essential mineral to the human body. It is important to receive an adequate supply in the body, through diet and supplements. However, low levels of potassium can be dangerous, especially to the heart. Too little of this nutrient in the body is a medical condition known as hypokalemia.

Weakness

• Hypokalemia is a serious condition that requires immediate medical attention. Weakness in the body is a possible sign you may be experiencing this condition. Another symptom accompanied with weakness is fatigue, where your body feels drained of energy.

Irregular Heartbeat

• The heart requires balanced levels of potassium to function. When these levels are reduced, the heart stops functioning as it should. An irregular heartbeat suggests you may have low potassium levels. You may have a weak pulse too. A heart with prolonged, irregular beating can cause serious damage to your body, and may lead to death, so it's important to be treated as soon as possible.

Digestive Problems

• When there is low potassium in the body, stomach and digestive issues may occur. You may experience abdominal cramping or bloating, a lack of appetite or constipation if your stomach region is affected. Another possible symptom is the inability to quench your thirst, even if you drink plenty of water or other hydrating fluids.

Causes

• A common reason there is too little potassium in your body and blood is a decline in the proper functioning of the kidneys. When their functioning is less than perfect, potassium begins to either increase or decrease in the bloodstream, because the body can no longer properly regulate the mineral. If you have a history of kidney dysfunction, ask your doctor to test your potassium levels during your annual physical.
