Which condition is a complication of severe burns leading to loss of muscle mass?

The condition that represents a complication of severe burns leading to the loss of muscle mass is muscle wasting. This phenomenon occurs as a direct result of the body's physiological response to severe burns, which can include increased metabolic demands, systemic inflammation, and the catabolism of body tissues, especially protein stores.

In severe burns, the body goes into a hypermetabolic state to support healing and recovery, where it breaks down muscle protein to meet energy needs. This leads to a decrease in muscle size and strength over time, often referred to as muscle wasting. Proper nutritional support and interventions are essential to mitigate this complication and promote recovery.

Cachexia denotes a syndrome characterized by weight loss, muscle wasting, and a decrease in appetite often associated with chronic diseases but isn't directly identified as a complication from burns, unlike muscle wasting. Atrophy is a general term for the reduction in size of any tissue or organ, often due to disuse or lack of stimulation, rather than being specific to burn injuries. Necrosis refers to the death of tissue and can occur in burns but is more related to localized damage than systemic muscle loss.
