What happens when a cancer patient loses too much weight?
Weight loss associated with cancer may be different than other types of weight loss. Doctors refer to a weight loss syndrome called “cachexia,” which is characterized by increased metabolism, loss of skeletal muscle, fatigue, loss of appetite, and decreased quality of life.
What is the mortality rate of cachexia?
Mortality rates of patients with cachexia range from 10–15 % per year in COPD through 20–30 % per year in chronic heart failure and chronic kidney disease to 80 % in cancer. The condition is also associated with poor quality of life.
How fast does cancer cachexia progress?
Presence of cachexia is identified from a weight loss of 10% or more within 6 months. The rate and amount of weight loss are directly related to survival in cancer patients .

Caring for the cachectic patient presents a frustrating and recurring dilemma. Cachexia is defined as ongoing weight loss, often with muscle wasting, associated with a long-standing disease. In cachexia, refeeding often does not induce weight gain.
Does chemo cause cachexia?
Cancer cachexia is a metabolic disorder involving perturbed energy balance and altered mitochondrial function. Chemotherapy is a primary treatment option for many types of cancer, but there is substantial evidence that some chemotherapeutic agents can also lead to the development and progression of cachexia.
