PHYSIOLOGICAL DEPENDENCE Meaning and
Definition
-
Physiological dependence refers to the physical reliance and adaptation of an individual's body to the presence of a substance, which can lead to a withdrawal syndrome if the substance is suddenly reduced or eliminated. This concept is primarily associated with addictive substances such as drugs or alcohol, although it can also extend to other behaviors or activities that trigger similar physiological responses.
When someone consumes a substance regularly and for an extended period, their body adjusts itself to accommodate the presence of that substance. This adjustment can manifest through various changes in the nervous system, brain chemistry, and other bodily functions. The body becomes accustomed to functioning with the substance, and its absence can cause significant physical discomfort or distress, commonly known as withdrawal symptoms.
Withdrawal symptoms differ depending on the substance, but they may include nausea, sweating, tremors, anxiety, insomnia, and even seizures in severe cases. Consequently, individuals may find it challenging to quit or reduce their consumption due to the discomfort associated with withdrawal.
It is important to differentiate between physiological dependence and psychological dependence. While physiological dependence refers to the body's response to a substance, psychological dependence is characterized by a compulsive desire and reliance on the substance to cope with emotional, mental, or social challenges. However, these two types of dependence are often interrelated and can influence each other in addictive behaviors.
In conclusion, physiological dependence is the physical reliance and adjustment of the body to the presence of a substance, resulting in withdrawal symptoms upon discontinuation. This concept is instrumental in understanding addiction and designing effective treatment approaches.
Etymology of PHYSIOLOGICAL DEPENDENCE
The etymology of the word "physiological" can be traced back to the Greek word "physis", meaning "nature" or "natural". The word "dependence" originates from the Latin word "dependēre", which means "to hang from" or "to rely on". Therefore, when combined, "physiological dependence" refers to a state of reliance or addiction that is rooted in the natural functioning of the body.
