Which involuntary weight loss percentage within 6 months is used in GLIM criteria for non-severe malnutrition?

• A. 2-4%
• B. 5-10%
• C. 10-20%
• D. 25-30%

Answer: (B)

In GLIM, involuntary weight loss is used to gauge how severely malnutrition is affecting someone. A loss of 5–10% over the past six months is considered moderate, which corresponds to non-severe malnutrition. Losses greater than 10% are viewed as severe. This distinction matters because diagnosing malnutrition with GLIM requires a phenotypic criterion like weight loss plus an etiologic criterion; identifying whether the weight loss is moderate or severe helps guide the level of intervention. The other ranges—2–4% (below the threshold for malnutrition), or 10–20% and 25–30% (both in the severe range)—don’t fit the non-severe category.
