People always go to the toilet after drinking alcohol usually because of the following factors: 1. The sensitivity of the central neurons in the brain is relatively reduced when drinking alcohol, and the central nervous system will be inhibited to a certain extent, so the anti-diuretic hormone produced will be reduced, and the effect of osmotic diuresis will occur because of the reduction of anti-diuretic hormone secretion, so the clinical symptoms and performance of frequent urination, urgent urination and always wanting to go to the toilet will occur. 2. The alcohol in the liver is rapidly converted into ethanol, which is decomposed into acetaldehyde under the action of hepatic ethanol dehydrogenase. acetaldehyde is a toxic and harmful substance that can dilate capillaries and ureters, and the expansion of ureters will lead to an increase in urine and the urge to go to the toilet with frequency and urgency. 3. the sugar in alcohol will increase the glomerular filtration rate after drinking, which will also lead to the urge to go to the toilet after drinking.
