Being diagnosed with HIV/AIDS may trigger drug or alcohol use, or risky sexual behavior because of substance abuse could possibly have caused the person to contract the illness. People who have HIV/AIDS, either on account of their drug use or as a pre-existing problem before their substance abuse problem, typically require treatment services tailored to fulfill their particular needs and challenges. A few of these challenges are physical in nature, due to the fact that substance abusers with HIV/AIDS rarely take care of themselves and take the proper medications they need to maintain their own health. As a result, these individuals arrive to rehabilitation in very poor health and this will have to be addressed as a priority whilst dealing with other critical concerns. Apart from the obvious necessity to supply medical services while in rehabilitation, people with HIV/AIDS should also deal with more deeply rooted issues which prompted their alcohol or drug use. Frequently, people have conditions within their lives which are strictly environmental which may have caused them to use drugs or alcohol, such as oppressive situations within their lives or negative relationships. These are the issues which rehabilitation professionals will give attention to as part of HIV/AIDS treatment services.
