Which symptom is NOT part of the cholinergic side effects?

Increased appetite is not considered a cholinergic side effect. Cholinergic side effects are typically associated with an overstimulation of the parasympathetic nervous system, which includes symptoms such as diarrhea, emesis (vomiting), and diaphoresis (excessive sweating).

Cholinergic effects enhance digestive processes and bodily secretions, leading to diarrhea and emesis as the body responds to increased cholinergic activity. Diaphoresis occurs because cholinergic stimulation also affects sweat glands, causing increased sweating. In contrast, an increase in appetite does not directly tie into the typical cholinergic side effects; rather, it is a more complex interaction influenced by various factors, not simply linked to cholinergic stimulation. Therefore, of the listed symptoms, increased appetite is the one that falls outside the scope of common cholinergic side effects.
