Alcohol use and abuse occurs with a tremendous amount of variability among individuals. Frequently, there is a limited distinction between "social" or "moderate" drinking and "problem" or" harmful" drinking. It is obvious however, that as the frequency of drinking and the amount increases, so does the probability of problem behaviors frequently resulting in medical and psychosocial problems. A very prominent group of individuals affected by alcohol problems to a significant degree, who develop the syndrome of alcohol dependence, are usually referred to by most people as alcoholics. different groups of individuals with alcohol problems usually require different approaches to diagnosis and clinical management.

The effects of alcoholism include the strong need to drink, a need that can be as strong as the need for food or water. Also, the drinker might not be able to stop once drinking has begun. Short-term memory loss can be imminent, as can be blackouts, where the user appears to others that he or she is awake and fully conscious - but in reality has no sense of time or action. These are only some of the early physical effects of alcoholism, which can lead to cirrhosis, liver failure, and ultimately death.

Alcohol withdrawal is a condition that follows a reduction in alcohol consumption or when an alcohol dependent individual stops drinking abruptly. In addition to a high level of distress, alcohol withdrawal is also associated with impairment in social, occupational, and other areas of an individual's functioning. Relatively uncomplicated cases of alcohol withdrawal are usually characterized by signs and symptoms of autonomic hyperactivity, and could possibly include increased heart rate, increased blood pressure, hyperthermia, tremor, nausea, vomiting, insomnia and frequently anxiety.

Teens are often very susceptible to the lure of alcohol. According to a 2004 survey of high school students by the U.S. Centers for Disease Control and Prevention, about 75% of high school students have at least tried alcohol. Many of them have had episodes of heavy drinking. It is a known fact that a leading death factor in teen-related car accidents is alcohol. Alcohol can affect the way the brain functions, especially the areas controlling decision-making and emotions, meaning that growth and development can be greatly hindered in teens if they drink alcohol. Memory and learning abilities can be affected, harming a teen's performance in school. The worst danger is that use of alchol in a teen can progress to abuse, and perhaps to addiction.

The first-ever study of its kind has found that kids as young as 12 can show a genetic-driven trend toward alcoholism. While looking to confirm that genes influence the body's response to alcohol -- how many drinks are needed to get drunk -- scientists found that the 12-year-olds who needed to consume the most drinks to get that desired "buzz" were most likely to already be on the road to problem drinking. The effects of alcohol abuse on adolescents is very different from the way problem drinking effects adult alcoholics. As you may expect, adolescents have a relatively short history of problem drinking. Because of their comparatively short history of heavy drinking, one of the major differences related to the effects of alcohol abuse on adolescents is that it is very rare to have physiological dependence on alcohol or alcohol-related medical complications. The abuse of alcohol and drugs however contributes in important ways to morbidity and mortality in adolescents, with the leading causes being motor vehicle accidents, homicide, and suicide. It is usually believed that when dealing with adolescents, given their economic and emotional dependence, whenever it is possible, it is important to have a thorough evaluation of the family in order to understand the adolescent's use of drugs as well as to understand the negative effects of alcohol abuse on them and their families.

Alcohol abuse is often associated with medical illness, which frequently becomes a common consequence of heavy drinking and also may occur in the absence of alcohol dependence. Early in the course of drinking, some individual's alcohol abuse problems may show no physical or laboratory abnormalities, but as drinking continues problems begin to manifest themselves in many of the body's organ systems. Obviously, a physical examination is necessary if there is any indication whatsoever of any medical problems. This physical examination will include important information about the presence and also the extent of any organ damage, and should be geared toward examining the organ systems most vulnerable to alcohol abuse including: the cardiovascular system, the gastrointestinal system, and the central and peripheral nervous systems. The physician will also be alert to other possible concerns related to alcohol such as alcohol withdrawal or delirium, intoxication or withdrawal from other drugs, and the acute presentation of psychological problems. Other nonspecific or systemic health problems associated with alcohol abuse include malnutrition, muscle wasting, specific vitamin deficiencies, infectious diseases (such as tuberculosis, dermatitis, pediculosis, and hepatitis), and trauma secondary to fights and accidents.

In order to be successful with treatment for alcohol abuse or dependence, the abuser must be willing to admit that there is a problem and that they want to stop drinking. There is also a physical aspect of the success of alcohol abuse treatment. If the drinker is physically dependent on alcohol, treatment can take a long time. Completely stopping to drink needs to be the first step, and then treatment focuses on relieving withdrawal symptoms. Afterwards, it focuses on staying sober. Some people may need medicine that help reduce the symptoms of withdrawal. Also, counseling and support groups are a fundamental part of treatment, as it helps with the mental aspect of recovering from alcohol abuse.
