Alcohol dependency, also known as alcohol use disorder (AUD), is a chronic condition characterized by the excessive and compulsive consumption of alcohol despite the negative consequences it may have on a person's health, relationships, and daily life. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), approximately 15 million adults in the United States have AUD.

There are several signs and symptoms that may indicate the presence of alcohol dependency. These can be physical, behavioral, and emotional in nature.

Physical signs of alcohol dependency include:

* Increased tolerance to alcohol, meaning that a person needs to drink more to feel the same effects [1].
* Withdrawal symptoms, such as tremors, sweating, nausea, and anxiety, when alcohol use is stopped or reduced [1].
* Neglecting personal hygiene and appearance [2].

Behavioral signs of alcohol dependency include:

* Drinking alone or in secret [1].
* Neglecting responsibilities at work, school, or home due to drinking [1].
* Engaging in risky behaviors, such as driving under the influence or having unprotected sex, while under the influence of alcohol [1].
* Continuing to drink despite negative consequences, such as legal problems or relationship issues [1].

Emotional signs of alcohol dependency include:

* Irritability, mood swings, and depression [1].
* Anxiety and restlessness [1].
* Loss of interest in activities and hobbies that were once enjoyed [1].

It is important to note that the presence of one or more of these signs does not necessarily mean that a person has alcohol dependency. However, if you or someone you know is experiencing these symptoms, it is recommended to seek professional help from a healthcare provider or a mental health professional.
