Unexplained weight loss not caused by reduced calorie intake or increased exercise is known as cachexia and may indicate a serious medical condition.
Is it true that unexplained weight loss not caused by reduced calorie intake or increased exercise is known as cachexia and may indicate a serious medical condition?
Yes. Unexplained weight loss driven by underlying systemic conditions rather than reduced calorie intake or increased exercise is defined as cachexia, a severe wasting syndrome often signaling serious underlying disease.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved papers consistently define cachexia as a wasting syndrome involving involuntary weight and muscle loss driven by systemic inflammation and metabolic dysfunction rather than simple caloric restriction, which supports the claim that it signifies serious underlying medical conditions such as cancer.
