Alcohol’s Effects on the Body National Institute on Alcohol Abuse and Alcoholism NIAAA

Although currently few treatments are available for tackling this significant health problem and providing relief for those suffering from the disease, there is hope. Schematic illustration of how problem drinking can lead to the development of dependence, repeated withdrawal experiences, and enhanced vulnerability to relapse. Alcohol dependence is characterized by fundamental changes in the brain’s reward and stress systems that manifest as withdrawal symptoms when alcohol consumption is stopped or substantially reduced. These changes also are purported to fuel motivation to reengage in excessive drinking behavior.

One size does not fit all and a treatment approach that may work for one person may not work for another. Treatment can be outpatient and/or inpatient and be provided by specialty programs, therapists, and health care providers. If you’ve had two or three of those symptoms in the past year, that’s a mild alcohol use disorder. Depending on how often you drink and how much, you may need support from a healthcare professional if you want to stop drinking. The connection between alcohol consumption and your digestive system might not seem immediately clear.

Studying Alcohol Relapse Behavior

This study provides an excellent example of the translational potential of basic research. Changes in the reinforcing value of alcohol during the transition from alcohol use and abuse to dependence reflect (counter)adaptive neural changes resulting from chronic exposure to high alcohol doses. As stated above, during the early stages of nondependent alcohol use, drinking behavior largely is motivated by alcohol’s positive reinforcing effects, whereas in the dependent state it likely is driven by both the positive and negative reinforcing effects of the drug. Multiple processes contribute to the increased motivation to seek drugs during the development of dependence. Sensitization refers to an increase in the reinforcement value of drugs following repeated exposures.

physiological dependence on alcohol

Patients with complex psychological issues related to trauma, sexual abuse or bereavement will require specific interventions delivered by appropriately trained personnel (Raistrick et al., 2006). According to WHO, alcohol is implicated as a risk factor in over 60 health disorders including high blood pressure, stroke, coronary heart disease, liver cirrhosis and various cancers. The AAF for alcoholic liver disease and alcohol poisoning is 1 (or 100% alcohol attributable) (WHO, 2000). For other diseases such as cancer and heart disease the AAF is less than 1 (that is, partly attributable to alcohol) or 0 (that is, not attributable to alcohol).

Similar results have been reported in mice, with voluntary alcohol consumption assessed using a limited access schedule (Becker and Lopez 2004; Dhaher et al. 2008; Finn et al. 2007; Lopez and Becker 2005). Likewise, studies using operant procedures have demonstrated increased alcohol self-administration in mice (Chu et al. 2007; Lopez et al. 2008) and rats (O’Dell et al. 2004; Roberts et al. 1996, 2000) with a history of repeated chronic alcohol exposure and withdrawal experience. Further, the amount of work mice (Lopez et al. 2008) and rats (Brown et al. 1998) were willing to expend in order to receive alcohol reinforcement was significantly increased following repeated withdrawal experience. This suggests that the reinforcing value of alcohol may be enhanced as a result of experiencing repeated opportunities to respond for access to alcohol in the context of withdrawal.

physiological dependence on alcohol

The kudzu root has been historically studied for its use in alcoholism; of particular interest are the extracts of the plant. The mechanism is not fully understood, but it is proposed that the extracts of the kudzu root may alter alcohol dehydrogenase or monoamine oxidase–acetaldehyde pathways,129,130 physiological dependence on alcohol leading to reduced alcohol consumption. Tiagabine107 and pregabalin108 both have open-label trials supporting their potential usefulness in alcohol dependence; however, placebo-controlled and head-to-head trials are needed to ascertain their particular place in therapy.

The adolescent therefore may continue drinking despite problems, which manifest as difficulties with school attendance, co-morbid behavioural difficulties, peer affiliation and arguments at home. All of this points to the importance of addressing the needs of family members of people who misuse alcohol. This includes the need for specialist treatment services to assess the impact of the individual’s drinking on family members and the need to ensure the safety of children living with people who misuse alcohol. Partners of people with harmful alcohol use and dependence experience higher rates of domestic violence than where alcohol misuse is not a feature. Some 70% of men who assault their partners do so under the influence of alcohol (Murphy et al, 2005).
