The findings were reviewed by external researchers with extensive research backgrounds on the consequences and benefits of alcohol consumption. This report now serves as the National Institutes of Health’s formal position paper on the health risks and potential benefits of moderate alcohol use. Dr. Koob began his career investigating the neurobiology of emotion, particularly how the brain processes reward and stress. He subsequently applied basic research on emotions, including on the anatomical and neurochemical underpinnings of emotional function, to alcohol and drug addiction, significantly broadening knowledge of the adaptations within reward and stress neurocircuits that lead to addiction. This work has advanced our understanding of the physiological effects of alcohol and other substance use and why some people transition from use to misuse to addiction, while others do not. Dr. Koob has authored more than 650 peer-reviewed scientific papers and is a co-author of The Neurobiology of Addiction, a comprehensive textbook reviewing the most critical neurobiology of addiction research conducted over the past 50 years.
Patterns of Drinking Associated with Alcohol Use Disorder
Alcohol misuse can also lead to high blood pressure, an irregular heartbeat (arrhythmia), or increased heart rate. Chronic, heavy drinking raises the risk for ischemic heart disease (heart problems caused by narrowed arteries) and myocardial infarction (heart attack). Heavy alcohol use can cause deficiencies in specific components of the blood, including anemia (low red blood cell levels), leukopenia (low white blood cell levels), thrombocytopenia (low platelet levels), and macrocytosis (enlarged red blood cells). In addition to its effects on the brain, alcohol also affects the peripheral nervous system, which comprises the nerves outside the brain and spinal cord. For example, alcohol misuse is linked to peripheral neuropathy, a condition that commonly occurs in people with severe alcohol use disorder (AUD) and can cause numbness in the arms and legs and painful burning in the feet.
Fall Semester-A Time for Parents to Discuss the Risks of College Drinking
Drinking culture is the set of traditions and social behaviours that surround the consumption of alcoholic beverages as a recreational drug and social lubricant. 2012—NIH announced the Trans-NIH Substance Use, Abuse, and Addiction Functional Integration to enhance the NIH Institute and Center (IC) collaborations around this important scientific and public health topic. The Functional Integration is a collaborative framework that draws on the collaboration among the NIH ICs on substance use, abuse, and addiction-related research.
2022—NIAAA released The Healthcare Professional’s Core Resource on Alcohol help healthcare professionals provide evidence-based care for people who drink alcohol. NIAAA launched Rethinking Drinking, a website and booklet, following extensive audience usability testing. Discover how many people with alcohol use disorder in the United States receive treatment across age groups and demographics.
The National Institute on Drug Abuse (NIDA)
2022—NIAAA released The Healthcare Professional’s Core Resource on Alcohol help healthcare professionals provide evidence-based care for people who drink alcohol. Created with busy clinicians in mind, the HPCR provides concise, thorough information designed to help them integrate alcohol care into their practice. NIAAA launched Rethinking Drinking, a website and booklet, following extensive audience usability testing. These resources offer valuable, research-based information enabling people to take a look at their drinking patterns and how these patterns may be affecting their health. The past 25 years of research have both diversified and consolidated our knowledge of alcohol problems. On the molecular scale, it appears that the diversity of alcohol’s addictive and medical effects can be attributed to its interference with a small number of key molecular processes common to all cells of the body.

The specific type of birth defect produced appears to depend on which organ systems are undergoing development at the time of alcohol alcohol’s effects on health national institute on alcohol abuse and alcoholism niaaa exposure (Webster 1989). Genetic alcoholism research began with the observation that alcoholism “runs in families.” To determine the extent to which this relationship is affected by biological inheritance, NIAAA has contributed to a variety of population genetics studies over the past 20 years. A combination of genetic and environmental factors influence vulnerability to alcoholism.
- Although older data suggested a possible disulfiram-like effect of metronidazole, newer data has challenged this and suggests it does not actually have this effect.
- For example, expectancies, particularly beliefs about the positive effects of alcohol, have been found to predict drinking behavior.
- These abnormalities may serve as trait markers for identifying persons at risk for the disease.
Studies using experimental animals have revealed that the actions of alcohol that cause intoxication, reinforce drinking behavior, and lead to addiction are based principally in the brain. NIAAA has dedicated a large proportion of its research effort to this area. An essential impetus to the development of alcoholism research was the acceptance of alcoholism as a medical disorder.

Therefore, NIAAA-supported investigators are using a new technique in animal studies called quantitative trait locus (QTL) mapping. This technique makes it possible to define the contribution of a single gene and its variations to complex behaviors that are determined by the interaction of many genes. Results of QTL mapping in animals can then be used to guide the search for similar genes in the human genome. The actions of alcohol on certain brain centers may lead to sensations perceived as rewarding, or pleasurable. The process by which a person learns to repeat rewarding behavior is called positive reinforcement. This process encourages the persistence of drinking in persons who are vulnerable for underlying genetic or psychosocial reasons (see below) (Wise and Rompre 1989).
- From its inception, NIAAA has supported studies in alcoholism genetics utilizing a range of techniques from the investigation of family pedigrees to the latest methods of molecular analysis.
- Drinking too much – on a single occasion or over time – can take a serious toll on your health.
- A product of neuroscience research, naltrexone is the first new medication in 45 years approved to help maintain sobriety after detoxification from alcohol.
- Because these disturbances permeate every organ and tissue in the body, they can contribute to endocrine-related health conditions including thyroid diseases, dyslipidemia (abnormal cholesterol levels in the blood), reproductive dysfunction, and stress intolerance, and diabetes.

What is A Standard Drink?
During recent years investigators have placed increasing priority on researching the prevention of alcohol-related problems. Until recently, prevention efforts were essentially limited to educational programs to inform people of the dangers of alcohol abuse and alcoholism. During the past 10 to 15 years, there has been an explosion of interest in complementing educational approaches with strategies aimed at altering the social, legal, and economic context in which drinking occurs (Holder and Wallack 1986). A research milestone of the 1970’s was the identification of FAS, a pattern of birth defects in children of heavy-drinking mothers.
Alcohol can interfere with absorption and storage of thiamine, vital for brain energy metabolism. This guide breaks it down simply—what’s happening, what’s reversible, what isn’t—and how to protect your brain while being honest about the risks and the context. NIAAA supports and conducts research on the impact of alcohol use on human health and well-being. Acute pancreatitis can turn into chronic pancreatitis, which is a condition of constant inflammation of the pancreas. Chronic pancreatitis is a risk factor for the development of pancreatic cancer and diabetes.
The pancreas is an organ that makes substances that support bodily functions including digestion and metabolism. Alcohol misuse over time can lead to pancreatitis, which can impair the production of digestive enzymes and can affect hormones that regulate blood sugar level. Drinking too much alcohol can weaken the immune system, making the body a much easier target for disease. Drinking a lot on a single occasion slows the body’s ability to ward off infections–even up to 24 hours later. Both acute and chronic heavy use of alcohol can interfere with multiple aspects of the immune response, the result of which can impair the body’s defense against infection, impede recovery from tissue injury, cause inflammation, and contribute to alcohol-related organ damage. Alcohol interferes with the brain’s communication pathways and can affect the way the brain looks and works.
