If a teen has alcohol use disorder, it means that they drink alcohol even though it's causing harm to themselves or others.
Alcohol use disorder can range from mild to severe. The more symptoms of this disorder your teen has, the more severe it may be. Teens who have it may find it hard to control their use of alcohol.
Teens who have this disorder may argue with others about how much they're drinking. Their schoolwork or job may be affected because of drinking. They may drink when it's dangerous or illegal, such as when they drive. Or they may engage in unsafe sex. This can lead to pregnancy and sexually transmitted infections. Their drinking may increase their risk of getting hurt or being in a car crash.
Teens may also have a strong need, or craving, to drink and feel like they must drink just to get by. It may get harder for your teen to say "no" to drinking. Your teen may start to find alcohol more fun than anything else. Or your teen may want to stop drinking but can't. Your teen's body may get used to alcohol. This is called physical dependence.
Teens may think that a drink or two is okay, even if it's illegal. Or they may think that it's okay if they're only drinking on the weekends. They may even think that binge drinking is okay. But teens who drink are more likely to develop alcohol use disorder than people who start drinking later in life.
Over time, drinking too much alcohol may cause health problems. These problems may include high blood pressure, liver problems, and problems with digestion.
