What physiological issue can arise from disordered eating?

Disordered eating can lead to a variety of physiological issues, and dehydration is one of the significant concerns. When individuals engage in disordered eating behaviors, they may not consume enough fluids, which can result in inadequate hydration. This condition not only affects bodily functions but can also impair physical performance and cognitive abilities.

Inadequate hydration can lead to consequences such as decreased muscle function, increased fatigue, and heightened risk of heat-related illnesses. Furthermore, the body's ability to recover after exercise is compromised when it's dehydrated, affecting overall health and fitness gains.

The other options suggest positive outcomes related to physical performance and well-being, which are generally not associated with disordered eating. Instead, disordered eating patterns often lead to negative health consequences that undermine athletic performance and overall energy levels, further reinforcing why dehydration is a key physiological issue that can arise from these unhealthy eating habits.
