Being diagnosed with HIV/AIDS may set off substance abuse, or dangerous sexual behavior due to substance abuse may have caused the individual to contract the illness. Individuals who have HIV/AIDS, either as a result of their drug use or as a pre-existing condition prior to their substance abuse problem, frequently require rehabilitation services tailor-made to fulfill their specific demands and challenges. Some challenges are physical in nature, because of the fact that substance abusers with HIV/AIDS hardly ever care for themselves and take the proper medications they need to preserve their health. As a result, they arrive to rehab in very poor health and this will have to be addressed as a priority while dealing with other important concerns. In addition to the obvious requirement to supply medical services while in treatment, those that have HIV/AIDS should also deal with deeper problems which brought about their drug or alcohol use. Often, individuals have conditions in their lives which are purely environmental which may have caused them to use drugs or alcohol, including oppressive situations in their lives or detrimental relationships. These are the concerns which rehab professionals will focus on as part of HIV/AIDS rehabilitation services.
