What causes cachexia?

A range of diseases can cause cachexia, most commonly cancer, congestive heart failure, chronic obstructive pulmonary disease, chronic kidney disease and AIDS. Systemic inflammation from these conditions can cause detrimental changes to metabolism and body composition.

What is the difference between cachexia and wasting?

Cachexia involves muscle wasting and weakness as a result of cancer-related inflammation, while sarcopenia involves muscle wasting and weakness as a result of age-related inflammation. Thus, the underlying pathological processes leading to muscle wasting and weakness differ between the two conditions.

How do you diagnose cachexia?

Cachexia is diagnosed by looking at a combination of body mass index (a calculation based on height and weight), lean muscle mass, and blood tests. Since cachexia is thought to often be present even before weight loss occurs, a high index of suspicion is important in recognizing the condition as soon as possible.

What cancers are associated with cachexia?

Cachexia occurs in many cancers, usually at the advanced stages of disease. It is most commonly seen in a subset of cancers, led by pancreatic and gastric cancer, but also lung, esophageal, colorectal, and head and neck cancer.

Where does cachexia start?

Even though the symptoms and signs of cachexia are usually noticed late in the course of cancer, we’re learning that the process leading to muscle wasting begins very early on after a diagnosis of cancer. As such, cachexia is often present before any weight loss occurs.
