Alcoholism is described as excessive alcohol consumption that leads to major mental or physical problems. Because of the disagreement over its definition, alcoholism is not a recognized diagnostic entity. The most popular diagnostic classifications are alcohol use disorder and alcohol dependence, both of which are defined in their respective sources. All organ systems can be harmed by excessive alcohol consumption, but the brain, heart, liver, pancreas, and immune system are the most sensitive. Alcoholism causes mental disease, delirium tremens, Wernicke–Korsakoff syndrome, irregular heartbeat, a reduced immune response, liver cirrhosis, and an increased cancer risk. Drinking during pregnancy can result in fetal alcohol spectrum diseases. They have a lower body weight, a lower capacity to metabolize alcohol, and a higher percentage of body fat. On the other hand, comprehension does not always imply action. If you know someone who needs some encouragement to begin living a healthy lifestyle, now is the time to sit down and remind them of what they need to do and why they should. It may be your husband who needs a little more encouragement to exercise a few times a week, or the mother of one of your children’s best friends who isn’t looking after herself and needs to set a better example for her children.
