Why I Became Sober

Acetaldehyde causes cancer.

You cure hangovers by not drinking alcohol. Acetaldehyde accumulation plays a significant role in the development and severity of hangovers. Acetaldehyde is a toxic byproduct formed during the breakdown of alcohol (ethanol) by the liver. The liver enzyme alcohol dehydrogenase (ADH) first converts ethanol into acetaldehyde, which is then further metabolized by another enzyme called aldehyde dehydrogenase (ALDH) into a less toxic substance called acetate. Acetate is eventually broken down into water and carbon dioxide, which the body can easily eliminate.

When alcohol is consumed in large quantities or over a short period, the liver may not be able to metabolize it efficiently, leading to the accumulation of acetaldehyde in the bloodstream. Acetaldehyde is highly reactive and toxic, causing damage to various tissues and organs, such as the liver, brain, and gastrointestinal tract.

The buildup of acetaldehyde contributes to the unpleasant symptoms of a hangover in several ways:

  1. Direct toxicity: Acetaldehyde is a highly toxic substance that can cause cell damage, inflammation, and oxidative stress. This can lead to various symptoms like headaches, gastrointestinal discomfort, and fatigue.
  2. Vasodilation: Acetaldehyde can cause blood vessels to dilate, leading to headaches and flushing.
  3. Gastrointestinal irritation: The presence of acetaldehyde in the digestive system can exacerbate alcohol-induced irritation of the stomach lining, leading to nausea, vomiting, and stomach pain.
  4. Neurotransmitter disruption: Acetaldehyde can interfere with the balance of neurotransmitters in the brain, contributing to mood swings, irritability, and feelings of depression or anxiety.
  5. Immune system response: The accumulation of acetaldehyde may trigger an immune response, which can lead to inflammation and contribute to the overall feeling of malaise associated with a hangover.

Individuals may experience varying levels of acetaldehyde accumulation during a hangover, depending on factors such as genetics, liver function, and the amount of alcohol consumed. Some people have a genetic deficiency in the ALDH enzyme, making them more susceptible to the toxic effects of acetaldehyde and prone to experiencing more severe hangovers.
