What is Hangovers?

21:55 - 4 May , 2021


They arise as a result of drinking a lot of alcohol the day before, causing general discomfort that includes thirst, fatigue, headache, muscle aches, nausea, anxiety, and dizziness, among other symptoms.

A hangover can happen to anyone regardless of the amount of alcohol they drink, but some are more prone to it because there is a genetic variation that affects how their body metabolizes alcohol in the blood, causing them to get sick after drinking just a glass.

Some conditions can facilitate the onset of a hangover, such as:

  • Drinking alcohol without having eaten anything.
  • Combining other drugs with alcohol.
  • Lack of sleep.
  • Drinking alcoholic beverages of a darker color.
  • Having close relatives with a history of alcoholism.
