Which of the following is a late stage symptom of HIV?

Rapid weight loss is indeed a significant late-stage symptom of HIV, often indicating progression to AIDS (Acquired Immunodeficiency Syndrome). In the context of HIV infection, weight loss occurs due to a variety of factors including metabolic changes, opportunistic infections, and the body’s struggle to fight off the virus. As HIV progresses, the immune system becomes increasingly compromised, leading to a decline in the overall health of the individual. This decline can result in a loss of appetite, malabsorption of nutrients, and increased energy expenditure, contributing to rapid and unintentional weight loss.

In contrast, the other symptoms, such as joint pain, frequent headaches, and skin rash, can be associated with earlier stages of HIV or even other conditions not related to HIV. While they may occur at different points in the disease process, rapid weight loss is more specifically tied to the advanced stages of HIV infection. Understanding these stages and their symptoms is critical for effective recognition and management of HIV-related complications.
