The influence of alcohol on the kidneys
Most of the alcohol absorbed is broken down in the liver to acetaldehyde. A smaller part, about one tenth, is excreted via the kidneys and lungs. If alcohol is consumed in moderation, there is no danger to the kidneys.
Excessive alcohol consumption, on the other hand, causes lasting damage to the kidneys and their function. The limit for men is about 24 grams of alcohol per day. For women, even 12 grams of alcohol per day is considered a critical quantity.
Alcohol has a cell-damaging (toxic) effect which, among other things, damages the cells of the kidneys. In addition, the urine excretion is favored. The body loses more water and can dry out (dehydrate).
People with impaired kidney function should take special care when drinking alcohol. As a result of the reduced filtration capacity, the cell toxin remains in the body for longer and can cause a progression of kidney disease in addition to increasing its effectiveness. In the worst case, acute kidney failure with complete collapse of the kidney function results.
