What does it mean when someone is described as cachectic?

When someone is described as cachectic, it refers to a state of physical wasting characterized by significant weight loss, muscle atrophy, fatigue, and often malnutrition. This condition is typically associated with chronic illnesses such as cancer, chronic obstructive pulmonary disease (COPD), or advanced heart failure, where the body's metabolism is altered, leading to a depletion of body resources.

Being cachectic indicates that the individual has lost not just weight but also muscle mass, which contributes to a frail and weakened appearance. This term comes from the Greek word "kachexia," meaning bad condition or ill health, and it emphasizes the seriousness of the underlying health issues. Understanding this term is essential in medical contexts, as it helps to identify patients who may require interventions for nutritional support and management of their chronic conditions.
