What Are the Symptoms of Alcohol Intoxication?

Visible Signs

When you consume too much alcohol, it can lead to intoxication and impairment. Some telltale signs of being drunk include slurred speech, lack of coordination, and unsteady balance. You may also experience nausea or vomiting as your body tries to expel the excess alcohol.

Mental Effects

Alcohol intoxication can significantly impact your mental state. You might feel confused, dizzy, or have trouble concentrating. In some cases, alcohol can even cause mood swings, aggression, or risky behavior due to lowered inhibitions.

Factors Affecting Intoxication

Several factors influence how quickly alcohol intoxication symptoms set in and their severity. These include your gender, age, body weight, food intake, medications, and overall health. Women tend to feel the effects faster due to differences in body composition and metabolism.

Recognizing the Warning Signs

If you or someone you know exhibits multiple signs like impaired speech, loss of coordination, confusion, or nausea after drinking, it could indicate alcohol intoxication. Being aware of the symptoms can help you take necessary precautions and seek medical assistance if needed.

How Alcohol Affects Your Brain and Body

Alcohol’s Impact on the Brain

Alcohol is a depressant that slows brain activity and impairs cognitive functions like decision-making, judgment, and self-control. It binds to receptors in the prefrontal cortex, affecting this critical area responsible for rational thinking. Over time, heavy drinking can cause shrinkage of the hippocampus, leading to issues with memory formation and recall.

In the short term, alcohol produces a numbing effect by depressing the central nervous system. This lowers inhibitions while impaired motor skills, judgment, and reaction time – increasing the risk of accidents or engagement in risky behaviors.

Effects on Major Organs

The liver bears the brunt when processing alcohol’s toxins. With normal drinking, liver cells can regenerate despite some dying off. But for heavy, long-term drinkers, continued strain raises the risk of fatty liver disease, fibrosis, cirrhosis, and liver failure.

Alcohol is also hard on the heart and cardiovascular system. It can weaken heart muscles over time, leading to diseases like cardiomyopathy. Binge drinking dehydrates the body and increases risks of stroke and high blood pressure.

Alcohol Withdrawal Dangers

When someone dependent on alcohol stops drinking, their brain chemistry is disrupted, causing uncomfortable and potentially dangerous withdrawal symptoms like tremors, anxiety, nausea, and even seizures. Medically-supervised detox through programs using medication-assisted treatment (MAT) helps restore brain function and manage cravings safely.

The 7 Stages of Alcohol Intoxication


  • Clear speech and movements
  • Minimal effects on coordination or thought processes


Feelings of well-being and relaxation set in. Minor impairment of reasoning and memory may occur, along with a slight loss of motor coordination.


Emotional instability and loss of judgment begin. Decreased sensitivity and increased reaction time occur. Vision becomes blurry and speech may start to slur.


Dizziness and immense sensory distortion are common. Decreased pain sensitivity, impaired gross motor skills and slurred speech continue to worsen. Nausea may also set in.


Little comprehension of the surrounding environment. Severe motor impairment and loss of feeling and consciousness. Vomiting is likely at this stage to prevent asphyxiation.


Unconsciousness and inability to be roused. Breathing may be impaired enough to induce coma or death due to suppressed respiratory reflexes.


Potential for complete respiratory failure and death from ingesting a massive amount of alcohol in a short period of time. This fatal dose varies per individual.

Behaviors to Watch for When Someone Is Intoxicated

Slurred Speech

One of the most noticeable signs of intoxication is slurred or incoherent speech. As blood alcohol levels rise, the brain’s ability to control muscle coordination diminishes – impacting the mouth and tongue movements needed for clear enunciation.

Loss of Balance

Alcohol is a depressant that slows down the brain’s communication pathways. This can manifest as stumbling, swaying, or an inability to walk in a straight line as motor skills and coordination become impaired.

Mood Changes

From giddiness to anger or sadness, drastic mood swings are common with alcohol intoxication. The brain’s emotional control centers are disrupted, leading to exaggerated or rapidly shifting emotional states.

Poor Judgment

Alcohol reduces the brain’s ability to rationally process information and assess risk. This can result in reckless behavior, impulsive decisions, or a lack of regard for personal safety or that of others.


As a central nervous system depressant, alcohol can induce feelings of drowsiness or sleepiness. In severe cases, an intoxicated person may pass out or lose consciousness entirely.
