Drug withdrawal
Effect on homeostasis[edit]
Homeostasis is the body's ability to maintain a certain chemical equilibrium in the brain and throughout the body. For example, the function of shivering in response to cold is to produce heat maintaining internal temperature at around 37 °C (98.6 °F). Homeostasis is impacted in many ways by drug usage and withdrawal. The internal systems perpetuate homeostasis by using different counter-regulatory methods in order to create a new state of balance based on the presence of the drug in the system.[2] These methods include adapting the body's levels of neurotransmitters, hormones, and other substances present to adjust for the addition of the drug to the body.[3]
Examples (and ICD-10 code) of withdrawal syndrome include:
