Substance Withdrawal Syndrome refers to a group of symptoms that occur when a person reduces or stops using a substance they are dependent on, such as alcohol, opioids, or benzodiazepines. These symptoms can vary in severity and may include anxiety, nausea, tremors, and sweating. The onset and duration of withdrawal symptoms depend on the substance used and the level of dependence. The syndrome is a significant concern in addiction treatment, as it can lead to complications if not managed properly. Medical supervision is often recommended during withdrawal to ensure safety and provide support. Treatment options may include medications to ease symptoms and therapy to address underlying issues related to substance use.
