Wasting Syndrome isn’t a specific disease. But if someone suffers from AIDS or cancer, they are prone to lose weight significantly. When they have lost at least 10% of their body weight, especially muscle, they are diagnosed with wasting syndrome. This syndrome is also known as cachexia and it is all related to unintentional weight loss. Because it forms part of an underlying chronic illness, there is no cure for this. But there are ways to help and better the symptoms.
