Men and women who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the person will have detoxification staff at their disposal around the clock to make certain that any complications are fixed as rapidly and safely as possible.
