Understanding Excess Cortisol and Its Effects

Excess cortisol, or hypercortisolism, can lead to various health issues, including increased muscle breakdown. During exercise, cortisol plays a crucial role in mobilizing energy sources, such as glucose and fatty acids, to fuel physical activity. When cortisol levels are elevated, it can lead to muscle protein breakdown and contribute to conditions like myopathy. Conversely, insufficient cortisol can also impair energy supply to muscles, resulting in increased risk for muscle injury and breakdown during exertion.
