Introduction
Drinking a bottle of 75% alcohol will severely damage kidney function, and there is no safe scenario. If any abnormalities occur, prompt medical attention is recommended. After entering the body, alcohol must be metabolized and excreted by the kidneys. The high concentration of 75% alcohol can directly irritate and damage renal parenchymal cells, impairing the kidney's filtration and excretion functions. In the short term, this may lead to acute kidney injury, manifesting as oliguria, edema, and other symptoms.
Under normal circumstances, drinking a bottle of 75% alcohol can severely damage kidney function, and there is no safe scenario. If any abnormalities occur, prompt medical attention is recommended. The specific analysis is as follows:
After entering the body, alcohol must be metabolized and excreted by the kidneys. The high concentration (75%) alcohol directly irritates and damages renal parenchymal cells, impairing the kidney's filtration and excretion functions. In the short term, this may cause acute kidney injury, leading to symptoms such as reduced urine output and edema.
Long-term or excessive consumption can lead to chronic kidney lesions, increase the burden on the kidneys, and trigger diseases such as nephritis and kidney failure. Additionally, high-concentration alcohol may cause multi-organ damage throughout the body, indirectly affecting kidney blood supply and function.
Never consume 75% alcohol, as it is intended for disinfection, not for drinking. Immediate medical treatment is required if ingestion occurs. Avoid contact with such high-concentration alcohol in daily life to protect organ health.
