Final answer:
The symptoms described suggest an electrolyte imbalance, possibly related to potassium or calcium levels.
Step-by-step explanation:
The symptoms described in the question are indicative of an electrolyte imbalance, specifically related to abnormalities in potassium and calcium levels. The presence of CARDIAC DYSRYTHMIAS suggests a potential problem with potassium levels. Hypokalemia, or low potassium levels, can lead to anorexia, nausea, vomiting, constipation, fatigue, diminished reflexes, lethargy, decreased level of consciousness, and confusion. On the other hand, hypercalcemia, or high calcium levels, can also cause similar symptoms, including constipation, fatigue, confusion, and lethargy.
