There are several possible reasons for the dizziness caused by drinking: first, alcohol enters the body and enters the blood circulation, when there is more alcohol in the blood of the brain, it will affect the normal energy uptake and metabolic process of brain cells, causing a lack of energy in brain cells or brain cell damage, resulting in temporary dysfunction of brain cells, which can cause dizziness as a phenomenon. Secondly, when alcohol enters the body, it will affect the higher functions of the central nervous system, such as the ability to judge space and position, thinking ability, orientation ability, etc. Especially alcohol can interfere with the normal physiological function of the cerebellum, because the cerebellum mainly plays the role of maintaining balance, if the function of the cerebellum is broken, it will lead to the feeling of dizziness.
