Final answer:
Hypokalemia, characterized by low blood potassium levels, is an electrolyte anomaly often linked to conditions causing paralytic ileus.
Step-by-step explanation:
The electrolyte anomaly associated with paralytic ileus is hypokalemia, which is an abnormally decreased blood level of potassium. Hypokalemia can result from various conditions, such as prolonged vomiting, diarrhea, or alkalosis, leading to an absolute reduction of potassium in the body. It is important to address this imbalance promptly as decreased extracellular potassium can produce paralysis and impact other bodily functions.
