What is a significant risk factor for Trey Johnson's post-treatment condition?

Nausea is a significant risk factor for Trey Johnson's post-treatment condition because it can be a common side effect of many medical treatments, especially chemotherapy or other similar interventions. Nausea can lead to complications such as dehydration, malnutrition, and can affect the patient’s overall recovery and rehabilitation process. Since it can impact a person's ability to eat and drink appropriately, nausea can exacerbate underlying health issues or lead to new complications, making monitoring and management crucial in a post-treatment care plan.

In contrast, increased hydration, improved physical stamina, and enhanced cognitive function are generally positive outcomes related to treatment and recovery. These aspects suggest a better overall health status and would not be considered risk factors in the context of post-treatment complications.
