Potassium deficiency leads to which condition?

Potassium deficiency leads to which condition?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypercalcemia

Answer: (A)

Potassium balance is essential for proper nerve and muscle function, especially in the heart. When potassium in the blood drops below normal levels, the condition is called hypokalemia. This deficiency disrupts muscle contraction and electrical activity in tissues, leading to symptoms such as muscle weakness, cramping, fatigue, and sometimes irregular heartbeats or constipation. It’s often caused by factors that increase potassium loss (like certain diuretics or vomiting), poor intake, or excessive sweating. Hyperkalemia means too much potassium, which produces a different set of effects on muscles and the heart. Hyponatremia is low blood sodium, and hypercalcemia is high blood calcium; neither describes a potassium deficiency, so they don’t fit the scenario.
