How Alcohol Metabolism Happens After Drinking Beer?

Do you know what occurs in the body once you drink a lot of beer?

Typically, while alcohol enters the body, it kicks off a chain of metabolic reactions mainly regulated by liver enzymes.

  • Due to this enzyme’s operation, an intermediate matter called acetaldehyde is created. This acetaldehyde begins the conversion procedure, which is one of the ways that alcohol makes you feel sick.
  • The acetaldehyde subsequently goes through an action that transforms it into acetate.
  • Once beer undergoes this stage of its metabolism, it’s mainly passed out of the body as water and carbon dioxide.
