What effect does hyperkalemia have on gastric motility?

• A. Increases
• B. Decreases
• C. No effect
• D. Causes paralysis

Answer: (A)

Hyperkalemia, which is defined as an elevated level of potassium in the blood, has a notable effect on gastric motility, primarily leading to a decrease rather than an increase. High potassium levels can disrupt the normal electrical activity of muscle cells, including those in the gastrointestinal tract, which may result in impaired muscle contractions and slower gastric emptying. Clinically, this decreased motility can lead to symptoms such as nausea, vomiting, and abdominal distension due to the delayed passage of contents through the gastrointestinal system. The correct understanding of hyperkalemia's impact on gastric motility is important for effective management of patients presenting with this condition, as addressing the underlying hyperkalemia may help alleviate associated gastrointestinal symptoms. The response indicating an increase in gastric motility does not accurately reflect the physiological changes associated with elevated potassium levels. Instead, the decreased motility should be recognized as a critical consequence of hyperkalemia.
