There is no single, universally accepted definition of alcoholism, mainly because there is not enough evidence to determine reliable diagnostic criteria. There are also no blood tests used to diagnose it. However, many people who suffer from alcoholism will exhibit several of these symptoms, which may include a strong need to drink alcohol, frequent and unsuccessful attempts to stop or limit drinking, consuming alcohol at inappropriate times, not fulfilling obligations because of alcohol abuse, and health problems caused by alcohol use. People who have alcoholism will often suffer from symptoms of withdrawal when they suddenly stop drinking, including sweating, shaking, anxiety, and sometimes seizures. These symptoms may require treatment at an alcohol withdrawal facility or detox program.
