Would drinking a bottle of 75% alcohol cause permanent damage?
Under normal circumstances, consuming a bottle of 75% alcohol without timely treatment to prevent severe organ damage may result in permanent harm. However, if vomiting is promptly induced, medical attention is received quickly, and the body's metabolic capacity is strong, permanent damage may be avoided. If there are any concerns, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

75% alcohol has a high concentration. If a bottle is consumed and vomiting or gastric lavage is not promptly performed, the alcohol can rapidly damage the gastrointestinal mucosa, potentially causing liver or kidney failure or irreversible damage to the central nervous system, which can lead to permanent injury.
If vomiting is immediately induced after consumption to reduce absorption, prompt medical treatment is received, and the individual has strong metabolic capacity and no underlying diseases, and the alcohol has not caused severe organ damage, recovery may gradually occur after appropriate care, potentially avoiding permanent harm.
75% alcohol is strictly prohibited for consumption. Regardless of the amount ingested, immediate medical attention is required after accidental ingestion. Delay should be avoided to prevent the alcohol from spreading and worsening the damage. When seeking medical care, inform the healthcare providers of the time and quantity consumed to enable timely and targeted treatment.
