What Causes Alcohol Withdrawal?

When someone drinks heavily or regularly over time, the brain adapts to the presence of alcohol. Because alcohol slows activity in the central nervous system, the body gradually compensates by increasing excitatory activity. When alcohol use suddenly stops, the nervous system can become overactive, leading to withdrawal symptoms.

The risk of withdrawal is often higher for people who:

• Drink heavily on a regular basis
• Have been drinking for many years
• Have experienced withdrawal before
• Have a history of seizures
• Use other substances alongside alcohol

What Does Alcohol Withdrawal Feel Like?

Alcohol withdrawal feels different for everyone, but many people describe it as both physically and emotionally uncomfortable. Common early symptoms include:

As withdrawal progresses, symptoms may become more severe for some individuals. Many people describe feeling on edge, unable to relax, emotionally overwhelmed, sensitive to noise and light, and physically exhausted but unable to sleep. The severity of symptoms often depends on the amount of alcohol consumed, length of use, overall health, and previous withdrawal history.

Common Alcohol Withdrawal Symptoms

Alcohol withdrawal symptoms may include:

Can Alcohol Withdrawal Cause Diarrhea?

Yes. Diarrhea can occur during alcohol withdrawal. The digestive system is often affected during the withdrawal process. Some individuals experience diarrhea, stomach cramps, nausea, vomiting, and loss of appetite. While diarrhea itself is usually not dangerous, dehydration can become a concern if symptoms are severe or prolonged.

Can Alcohol Withdrawal Cause Psychosis?

Yes. Alcohol withdrawal can cause psychosis in some cases. Severe withdrawal may result in hallucinations, delusions, extreme confusion, and paranoia. Alcohol-related psychosis can occur during severe withdrawal and should always be treated as a medical emergency.

Can Alcohol Withdrawal Cause High Blood Pressure?

Yes. High blood pressure is a common alcohol withdrawal symptom. As the nervous system becomes overactive, individuals may experience elevated blood pressure, rapid heart rate, sweating, anxiety, and tremors. For people with existing heart or vascular conditions, medical supervision may be especially important during withdrawal.

Can Alcohol Withdrawal Cause Headaches?

Yes. Headaches are very common during alcohol withdrawal. Several factors may contribute to withdrawal headaches, including dehydration, sleep disruption, increased blood pressure, and stress on the nervous system. Headaches often improve as withdrawal symptoms begin to resolve.

Can Alcohol Withdrawal Cause Shortness of Breath?

Yes. Shortness of breath can occur during alcohol withdrawal. Some individuals experience anxiety-related breathing difficulties, rapid breathing, panic attacks, and feelings of chest tightness.

Can Alcohol Withdrawal Cause Permanent Damage?

This is a common concern among people considering sobriety. For most individuals, alcohol withdrawal symptoms themselves are temporary and improve with time. However, severe alcohol withdrawal can become dangerous if left untreated. Complications may include:

In addition, long-term heavy alcohol use can cause damage to organs such as the liver, heart, pancreas, and brain. The earlier someone seeks help, the better the opportunity to prevent ongoing harm and begin healing.

When Is Alcohol Withdrawal Dangerous?

Alcohol withdrawal should always be taken seriously. Medical evaluation is particularly important if someone has a history of severe withdrawal, previous withdrawal seizures, hallucinations, delirium tremens, significant medical conditions, or heavy daily alcohol use. Unlike withdrawal from many other substances, alcohol withdrawal can be fatal in some cases without proper treatment.
