Which of the following is a potential side effect of the therapy?

• A. Nausea only
• B. Hair growth acceleration
• C. Weight loss only
• D. New skin cancers

Answer: (C)

Side effects come from how a drug affects normal tissues and metabolic processes, not just from what it treats. For this therapy, weight loss is a plausible adverse effect because it can reflect changes in appetite, taste, gut function, or overall energy balance caused by the drug’s systemic actions. These kinds of metabolic or appetite-related effects can occur even if other symptoms aren’t present.

Nausea, while common with many treatments, isn’t indicated here as a potential side effect based on this therapy’s known profile, so it’s less likely. Hair growth acceleration would suggest a hormonal or growth-promoting action that this therapy doesn’t produce. New skin cancers imply a long-term carcinogenic effect tied to UV exposure or specific DNA-damaging mechanisms, which isn’t associated with this treatment’s mechanism. Therefore, weight loss stands out as the plausible adverse effect among the options.
