高耐疼性是小胖威利另一重大的潜在风险

小胖威利的一些常见特征包括肌肉张力差、体温调节不准确、行为问题、智力障碍、缺乏呕吐反射和高食欲，这些都可以掩盖疾病或其严重程度。

医生问你的孩子是否困倦、发烧、呕吐或不想吃东西，这可能无关紧要。可能需要进一步的测试，如扫描或x射线，以对疾病做出更准确的评估，父母的直觉不应被忽视。

疾病的另一个主要指标是疼痛。如果有人感到痛苦，他们会说出来，或者你会从他们明显的不适中感受到。但小胖威利的患者对疼痛有很高的耐受性，这可能是潜在的危险，或者他们可能会感到一些不适，但可能无法确定疼痛来自哪里。

例如，阑尾炎等严重疾病会导致大多数人剧烈疼痛，但可能会被小胖威利患者忽视，或者对他们来说只是一种轻微的不适；有时小胖威利因扭伤脚踝导致的跛行可能会被证明是骨折。

英文原文

Some of the common characteristics of PWS include poor muscle tone, inaccurate body temperature regulation, behavioural issues, intellectual disability, lack of gag reflex and an insatiable appetite.  All of which can mask an illness or its severity.

A doctor asking if your child is sleepy, has a fever, has vomited or is off their food can be irrelevant.  Further testing, like scans or x-rays may be required to make a more accurate assessment of an illness and a parent’s instinct should not be ignored.

The other main indicator of illness is pain.  If someone is in pain they would say so or you would know by their obvious discomfort.  People with PWS have a high tolerance to pain, which can be potentially dangerous, or they may feel some discomfort but may not be able to localise where it is coming from.

For example, a serious condition such as appendicitis would cause severe pain in most people, but may pass unnoticed or be a minor upset for a person with PWS, or a limp from what was thought a sprained ankle may turn out to be a fracture.
