Which of the following is a common side effect of SSRIs?

Weight gain is indeed a common side effect associated with selective serotonin reuptake inhibitors (SSRIs). SSRIs, which are frequently prescribed for conditions such as depression and anxiety, work by increasing the levels of serotonin in the brain, which can influence mood and appetite. As this medication can alter metabolic processes and appetite regulation, some individuals may experience weight gain during treatment.

While SSRIs can improve mood and potentially lead to better focus and clarity through their antidepressant effects, this is not recognized as a direct side effect of the medication itself. Therefore, it is not listed among the common side effects of SSRIs.

Similarly, brittle hair and decreased energy levels are not typically categorized as common side effects of SSRIs. While some patients may experience changes in their hair or energy levels, these effects are less frequently reported and do not reflect the broader experience of individuals taking these medications. Thus, weight gain is the most commonly acknowledged side effect in this context.
