Physical dependence

Introduction So-called body dependence, also known as physical dependence or physiological dependence. It is the body's dependence on drugs caused by long-term, repeated use of drugs. The main manifestation is that the body must be maintained under sufficient conditions to maintain a normal state. Once the drug is stopped, the human body's physiological and biochemical processes will produce a series of reactions such as abnormalities and disorders, namely withdrawal syndrome. The reaction of drugs, drugs, odors, etc. to human physiology and nervous system. Tolerance and sensitization (sensitization) are two distinct manifestations of adaptive changes in the central nervous system.

Cause

The reaction of drugs, drugs, odors, etc. to human physiology and nervous system.

Tolerance and sensitization (sensitization) are two distinct manifestations of adaptive changes in the central nervous system. Tolerance means that after repeated use of a certain drug, the sensitivity to the drug is lowered, and the dose needs to be increased to produce the original effect. Contrary to the role of tolerance, sensitization refers to the increased body dependence of drugs after repeated use of drugs, mainly due to the adaptation of the central nervous system to long-term use of dependent drugs, including increased tolerance and discontinuation. Withdrawal symptoms after the drug.

Drugs act on the human body, causing adaptive changes in the body's physical energy, forming a new equilibrium state under the action of drugs. Once the drug is stopped, the physiological function will be disordered and a series of serious reactions will occur.

Various drugs with potential dependence produce different symptoms of physical dependence, and there is no ideal single indicator that reflects physical dependence. Therefore, multiple indicators are needed for comprehensive evaluation. Physiological indicators can be used for body weight, body temperature, breathing, diet, etc.; in behavioral models, indicators that reflect changes in motor function, learning ability, memory ability, and motivation behavior can be used.

Differential diagnosis

(1). Physical dependence:

Due to a strong dependence caused by repeated medications, drugs act on the human body, causing adaptive changes in the body's physical energy, forming a new equilibrium state under the action of drugs. Once the drug is stopped, the physiological function will be disordered, and a series of serious reactions, called withdrawal reactions, will cause people to feel very painful. In order to avoid the withdrawal reaction, the drug users must regularly take the drug and continue to increase the dose so that drug users can not be separated from drugs.

(2). Mental dependence

When drugs enter the human body, they act on the human nervous system, causing drug users to have a strong desire to use drugs, driving drug users to seek and use drugs desperately. Once mental dependence occurs, even after detoxification treatment, it is often several months or even years to fully recover the original physiology after the acute withdrawal control is basically controlled. More seriously, dependence on drugs is difficult to eliminate. This is the reason why many drug users are taking drugs in one place and again. It is also a problem that the world medical and pharmaceutical circles have yet to solve. Drugs act on the human body, making the body's physical energy adaptable and forming new drugs under the influence of drugs. Balanced state. Once the drug is stopped, the physiological function will be disordered and a series of serious reactions will occur.
