How long does a person live with cachexia?

Cachexia is a wasting syndrome that can occur in people with advanced cancer, chronic kidney disease, heart failure, and other serious illnesses. It is characterized by extreme weight loss, muscle atrophy, and fatigue. Cachexia can significantly shorten a person's life expectancy, but the exact prognosis varies depending on the underlying illness and the severity of the cachexia.

In some cases, cachexia can be managed with nutritional support and medications, which may help to improve a person's quality of life and extend their life expectancy. However, in other cases, cachexia may be refractory to treatment and can lead to death within a few months or even weeks. The average survival time for people with cachexia varies widely, but it is typically less than one year.

It is important to note that cachexia is a complex condition and the prognosis for each individual will depend on a variety of factors, including the underlying illness, the stage of the disease, and the individual's overall health.
