Hangover: causes, symptoms, treatments and preventions

Everyone who drinks alcohol has suffered from hangover at least once, and each person will have their own hangover solution. However, not many people know exactly how hangover occurs and how to prevent or effectively eliminate it. So, here’s an easy explanation of the mechanism of hangover and how to prevent and eliminate it.

Causes of hangover

  • Hangover is caused by various metabolic processes and reactions in our body that respond to excessive alcohol absorption. Alcohol increases urinary excretion, which in turn leads to dehydration and causes symptoms such as thirst and dizziness.
  • Alcohol stimulates the inflammatory response of the immune system. These inflammatory reactions can cause a variety of symptoms, including decreased concentration, decreased memory, decreased appetite, and weakness.
  • Alcohol may irritate and damage the gastric mucosa. It also increases the secretion of stomach acid and increases the amount of time food stays in the stomach. All of these changes cause nausea, vomiting, and abdominal pain.
  • Alcohol can also lower blood sugar. As a result, too low blood sugar can lead to fatigue, weakness, shaking hands, mood disorders, as well as convulsive seizures.
  • Alcohol can dilate blood vessels and cause headaches.
  • Alcohol causes drowsiness, but deep sleep interferes.
  • Additives or fermentation by-products from alcohol can also cause hangover. Alcohol contains several types of additives or fermentation by-products called congeners. In general, colored liquors such as beer, brandy, and bourbon contain more additives or fermentation by-products than transparent liquors such as soju and vodka.
