Final Answer:
The diagnosis is made when there is a weight loss of c) 15 %or more of body weight.Therefore the correct answer is c) 15%.
Step-by-step explanation:
Body weight loss is a crucial indicator in diagnosing various health conditions, and a threshold is set to determine when the weight loss becomes significant. In this context, a weight loss of 15% or more is the criterion for diagnosis.
The calculation involves assessing the percentage of weight lost relative to the initial body weight. For instance, if someone initially weighs 70 kilograms and loses 15% of their body weight, the calculation would be 70 kg * 0.15 = 10.5 kg.
Therefore, when the weight loss exceeds or equals 10.5 kg, reaching or surpassing the 15% mark, it becomes a diagnostic criterion.
Understanding this threshold is essential for healthcare professionals to identify and address potential health issues related to significant weight loss. Such weight loss can be indicative of various medical conditions, ranging from metabolic disorders to chronic illnesses.
The 15% threshold helps establish a clear and standardized guideline for healthcare practitioners, ensuring consistency in diagnosis across different cases. Monitoring and addressing significant weight loss early can contribute to more effective interventions and improved patient outcomes.
Therefore the correct answer is c) 15%.
