Potassium deficiency, also known as hypokalemia, indicates lower-than-normal levels of potassium in the blood. It can be caused by various factors, such as kidney disorders, gastrointestinal conditions, certain medications, hormonal imbalances, or inadequate potassium intake. Potassium deficiency can affect multiple bodily functions and may lead to symptoms like muscle weakness, fatigue, abnormal heart rhythms, constipation, digestive issues, mood changes, and other complications. Addressing potassium deficiency is important to prevent potential complications and maintain overall health and well-being.
