Numbness of the tongue after drinking is mainly related to peripheral nerve damage, such as affecting the sensory nerves of the tongue, stimulating blood vessels and damaging taste buds.
1. Affecting the sensory nerves of the tongue: Alcohol contains a large amount of ethanol, which will stimulate the sensory nerves of the tongue and cause nerve damage and dysfunction, which may cause numbness of the tongue.
2. Stimulate blood vessels: ethanol in alcohol into the brain will stretch the blood vessels in the brain, thus causing insufficient blood supply locally or insufficient blood supply to the brain, which affects the function of the central nervous system, and the tongue appears numbness, dysfunction and other symptoms.
3. Damage to taste buds: In addition to destroying the tongue sensory nerves, ethanol in alcohol will also damage the taste bud cells, affecting the sensation of the tongue, resulting in numbness of the tongue.
If the tongue is numb for a long time, you need to go to the hospital in time to find out the cause and carry out targeted treatment.
