Physical Effects of Alcohol Withdrawal

Physical effects of alcohol withdrawal can range from mild to life-threatening, depending on the level of chemical dependence the person has developed. The earliest sign of alcohol withdrawal is the hangover, which occurs in most people who drink to excess, even if they don't do so very often. The majority of people only experience relatively mild physical effects from alcohol withdrawal, but anyone with serious dependence should consult a physician before quitting cold turkey.

Shakiness

• Mild physical effects of alcohol withdrawal include hand tremors or shakes, especially in the morning, along with a feeling of restlessness or jumpiness and a rapid heartbeat.

Hangover-Type Symptoms

• Nausea and a headache can also occur as alcohol withdrawal symptoms, as with a general hangover.

Sleep Disorders

• People experiencing alcohol withdrawal may have insomnia or bad dreams and fatigue.

Hallucinations

• More serious physical effects include visual hallucinations that begin up to 48 hours after not drinking.

Severe Effects

• The most severe physical effects of alcohol withdrawal include seizures and cardiovascular disturbances. At this level of withdrawal, delirium tremens also can result, causing profound disorientation, hallucinations and hyperactivity.
