What does the term cachectic describe?

The term "cachectic" refers to a state of extreme physical wasting and malnutrition, often associated with chronic illness. It describes a significant loss of weight and muscle mass that typically results from diseases such as cancer, chronic infections, or advanced stages of various illnesses. In cachexia, individuals may appear extremely thin, frail, and lacking in energy, which is a distinct condition from being merely thin or underweight, as it is linked to underlying medical issues that affect the body's metabolism and ability to maintain weight and nutrition. This term highlights the severity of the physical condition rather than just a measurement of body weight or composition.
