Physical dependence is a condition in which a person’s body has adapted to a particular substance and becomes dependent on it in order to function normally. Dependence is indicated by physical symptoms that occur after the substance has stopped being used or when the dose is reduced.
Physical dependence is distinct from psychological dependence, which is an emotional need or compulsion to use a substance.
Physical dependence results from changes in the body that occur over time, with the body becoming used to having certain amounts of the substance present. These changes can cause the person to experience unpleasant physical symptoms, such as sweating, shakes, nausea and vomiting, when the substance is not present or the dose is reduced.
Withdrawal symptoms, which are physical and mental symptoms that occur when an individual stops using a substance to which they have become physically dependent, can vary in intensity and duration. Depending on the individual and the specifics of their situation, such as how long they have been using a substance, withdrawal symptoms can range from mild to severe.
Severe physical withdrawal symptoms can put an individual at risk and should be managed with medical supervision.
