Attrition syndrome, also called consumptive syndrome, wasting or wasting is a process associated with HIV infection. It is the involuntary loss of at least 10% of the initial body weight in the presence of diarrhea, more than two bowel movements per day, fever or chronic weakness.

Wear syndrome is usually one of the first symptoms of AIDS, and may also occur during the latency or asymptomatic phase with diffuse clinical signs. It is also the main manifestation of the precocious symptomatic complex, a condition that precedes AIDS.
