What percentage of body weight loss in 30 days is a key indicator of undernutrition?

1. 5%

2. 10%

3. 15%

4. 20%

The correct answer is: 5%

Losing 5% of body weight within 30 days is considered a significant indicator of undernutrition because it suggests that the body is not receiving adequate nutrients to maintain its normal functions. This level of weight loss triggers a clinical concern that a more profound assessment of nutritional status and support may be necessary. Weight loss at this rate may result from various factors such as illness, inadequate dietary intake, or malabsorption, and it typically signifies that the individual may be at risk of ongoing health complications. Health care professionals recognize that a 5% weight loss is often the threshold at which further evaluation and intervention may be warranted to prevent further deterioration of the patient's nutritional status and overall health. In contrast, while the higher percentages indicate more severe weight loss and should also be taken seriously, the 5% mark is crucial for early intervention strategies in managing undernutrition. Recognizing this early signal helps health care providers implement necessary dietary adjustments or treatment plans promptly, potentially mitigating more substantial health issues down the line.
