What Causes Hallucinations? 14 Common Causes (You Should Know)

Alcohol Withdrawal

When heavy drinkers suddenly quit or reduce alcohol consumption significantly, they may experience symptoms of alcohol withdrawal syndromes or AWS. These may include emotional and physical experiences ranging from mild fatigue and nausea to feelings of anxiety. In severe cases, it may result in life-threatening seizures and hallucinations. Other symptoms that may occur from alcohol withdrawal are tremors, vomiting, headaches, elevated heart rate, sweating, irritability, confusion, and night terrors.

Typically, the milder symptoms persist for weeks on end in some, worsening in the first two to three days. The more severe type of the syndrome is called delirium tremens or DT, with extreme confusion and agitation, fever, visual and auditory hallucinations, and fast respiration. Those who experience these symptoms are advised to seek immediate medical attention. It’s vital to call for help or get to the nearest emergency room because they can be dangerous. 

Depending on the symptoms’ severity, treatment for AWS can be done at home with family or loved ones monitoring your condition or in the hospital for medications. The sedatives generally used for this condition are benzodiazepines, chlordiazepoxide, and lorazepam. Additionally, vitamin supplements might be needed to replace depleted nutrients.
