Y91: Evidence of alcohol involvement determined by level of intoxication

The conditions encompassed by the Y91 group are characterized by varying degrees of alcohol involvement or intoxication, confirmed by clinical assessment and the individual's observable behavioral and physical symptoms. The severity of these conditions depends on the level of alcohol consumed and an individual's physiological response. Symptoms can range from minor behavioral changes, such as lowered inhibitions and exaggerated emotions, to severe physical symptoms, such as compromised balance, cognitive dysfunction, and potentially life-threatening loss of vital functions at very high levels of intoxication. Chronic heavy drinking can lead to a variety of long-term health implications including liver disease, heart disease, and neurological damage. It's important to note that alcohol use doesn't directly cause these conditions; rather, they are a consequence of the harmful effects of excessive alcohol consumption.
