Rheumatoid cachexia refers to the loss of muscle mass and strength due to rheumatoid arthritis (RA). It’s often called muscle wasting.
About two thirds of people with RA experience this complication if they don’t control their RA.
Muscle wasting adds to the tired, achy feeling that people with RA experience. It can also cause serious complications like heart disease. People with RA who have muscle wasting may have a shorter life expectancy.
Read on to see how cachexia is identified, understand what causes it, and learn what you can do to keep yourself healthy.

Weight changes and muscle wasting
There are many reasons a person with RA may have changes in their weight. People with RA often exercise less over time because of the discomfort of RA, and that can make them gain weight.
Alternately, people may become depressed, eat less, and lose weight. It’s important to note that not all people with cachexia will undergo weight loss. People with cachexia may even gain fat, leading to an overall increase in weight.
The exact causes of muscle wasting are hard to identify. There seems to be a connection with having too much of a protein (cytokine) produced by immune system cells.
Obesity also may play a role, especially when the person’s diet is high in saturated fat. A lack of resistance exercise is also related to muscle wasting.
People with RA may not want to exercise because of the pain and difficulty in moving their joints. This lack of activity can lead to muscle wasting.
While there are no known cures for muscle wasting, you can do a lot to halt deterioration and build back muscle. Resistance exercise can prevent lean muscle loss, increase range of motion, and reduce the pain of RA.

Medications that tend to help treat rheumatoid cachexia are the same drugs used to treat RA. Medications that treat RA and may also improve muscle mass include:
Cachexia is a serious complication for people with RA. Lean muscle mass loss leads to pain, fatigue, depression, accidents caused by poor balance, and even heart failure.
