A low potassium level—also known as Hypokalemia—is one of the most common electrolyte abnormalities seen in clinical practice. But what does it actually mean for your health? In this video, we break down exactly why potassium is essential for the body, and how low levels can disrupt critical functions such as nerve signaling, muscle contraction, and the rhythm of your heart. You’ll learn how hypokalemia can lead to symptoms like weakness, paralysis, and dangerous heart rhythms such as ventricular tachycardia—and why, in some cases, it requires urgent treatment. We also explore the most common causes of low potassium, including medications like diuretics, vomiting and diarrhea, hormonal and hereditary conditions, and even the role of magnesium deficiency in preventing potassium levels from correcting. If you’ve ever been told your potassium is low on a blood test, this video will help you understand what it means, what to watch for, and when it becomes a serious medical concern: https://youtu.be/0ZTBgh19_RA
