Cachexia (pronounced kuh-KEK-see-uh) is a “wasting” disorder that causes extreme weight loss and muscle wasting, and can include loss of body fat. This syndrome affects people who are in the late stages of serious diseases like cancer, HIV or AIDS, COPD, kidney disease, and congestive heart failure (CHF).

What are the outcomes of cachexia?

The disease causes involuntary weight loss, muscle wasting, and often a decrease in body fat. The loss of skeletal muscle may lead to physical weakness and impairment. According to estimates, more than 160,000 people are hospitalized with a cachexia diagnosis every year in the United States.

Can you survive cachexia?

Cachexia not only worsens survival for people with cancer, but it interferes with quality of life. People with cachexia are less able to tolerate treatments, such as chemotherapy, and often have more side effects. For those who have surgery, postoperative complications are more common.

Cachexia, however, is a multi-organ syndrome that, in addition to muscle, affects adipose tissues, the heart, intestine, kidneys and liver2.

How does cachexia cause death?

Cardiac muscle

Cardiac alterations are typical in cancer patients11 and ultimately results in heart failure and arrhythmia, which are two of the concurring causes of death during cachexia. Similarly to skeletal muscle, cardiac wasting involves the activation of protein turnover mediated by the UPR system.
