What is it?
Weight loss and progressive wasting syndrome are two AIDS-related complications if not treated properly, can be life threatening. Although anti-HIV therapies have helped reduce the risks of weight loss and progressive wasting syndrome, are still occurring. According to a study published in late 1997, up to 25% of HIV positive persons receiving triple therapy for HIV drugs, continue to experience some degree of weight loss and / or progressive wasting syndrome.
Is there a difference between weight loss and wasting syndrome?
Yes, as its name implies, the weight loss refers to loss of body weight. The progressive wasting syndrome refers to the mass loss or decreased body size, muscle mass being the most notable loss (sometimes called “lean body mass“). Often, both occur simultaneously, but not always. Someone may be losing weight, not losing muscle mass. It is also possible that someone who is losing muscle mass, not drop much weight. For example, some people with HIV lose plenty of muscle. However, experience an increase in fat. This would allow the weight to be conserved, but continued loss (wasting) of muscle mass.
In HIV-negative people, weight loss is generally not a major problem. For example, someone who is on a diet, lose weight at some point. The body will burn fat from the blood or cellular deposits, to obtain the food they did not get through to get food and energy it needs. At the same time, the body works to protect proteins during periods of diet or physical activity. Protein is needed to build muscle, cells and organs. In other words, most people can tolerate the loss of fat, but can not bear the loss of protein.
