HIV-related conditions refer to health issues that arise due to the weakened immune system caused by the HIV virus. When left untreated, HIV can progress to AIDS (Acquired Immunodeficiency Syndrome), making the body more susceptible to infections and certain cancers. Common conditions include opportunistic infections like pneumocystis pneumonia and tuberculosis, which can be life-threatening. People living with HIV may also experience chronic conditions such as cardiovascular disease and kidney disease due to long-term effects of the virus and its treatment. Regular medical care and antiretroviral therapy can help manage these conditions and improve overall health.
