There are many side effects of alcohol consumption. You must take into consideration the amount of alcohol that you drink, and the circumstances in which you drink it. The more alcohol you drink, the more severe the side effects are.

Stages of alcohol consumption

Depending on the amount of alcohol consumed, alcohol consumption causes the body to go through different stages. Here, we talk about each stage and the impact of each.

  1. The first stage of alcohol consumption is a feeling of excitement, euphoria and losing any sense of shame.
  2. Intoxication begins during the second stage. Therefore, this affects your nervous system and you lose the ability to coordinate movements and start to lose your balance.
  3. The third stage is the hypnotic phase. Here you feel confusion, tiredness, nausea with vomiting and start to suffer headaches.
  4.  The fourth stage is anesthesia. You become incoherent, lose muscle strength and you cannot control the urge to urinate.
  5. The most critical stage is the fifth one. This stage can eventually result in cardiac arrest and death.

Effects of alcohol consumption on your body

Many of the effects of alcohol consumption on your body aren’t immediate, and appear over time. Some of these effects include:

  • Impact on your nervous system: causing mood changes, slurred speech, slower reactions and loss of balance.
  • Altering neurotransmitter actions and changing their structure and functions. This produces a series of consequences: it affects your ability to react, your reflexes are slow, you lose the ability to coordinate movements. It also causes tremors and hallucinations. You lose self-control and your memory, the ability to concentrate and your motor functions are seriously impacted.
  • Serious damage to brain cells.
  • Decrease in levels of vitamin B1. This can result in Wernicke-Korsakoff syndrome. This disease alters feelings, thinking and memory.
  • Produces sleep disorders- common in people who consume alcohol.
  • In very high doses, alcohol can put you in a coma, which causes very serious mental alterations.
  • Some cases present periods of anemia, increased blood pressure and damage to the heart muscle.
