What effects does alcohol have on mental health?
Alcohol changes the way your brain cells signal to each other, which can make you feel relaxed.

Drinking alcohol is so common that people may not question how even one beer, cocktail, or glass of wine could impact their health.

Your body can’t make the numbers of white blood cells it needs to fight germs. So for 24 hours after drinking too much, you’re more likely to get sick. Long-term heavy drinkers are much more likely to get illnesses like pneumonia and tuberculosis. If AUD is not treated, it can increase your risk for serious health problems. After completing treatment for AUD, it’s possible to have a risk of relapse. It’s important to recognize warning signs and seek help if you’re concerned about having a relapse.

The pancreas is essential for breaking down enzymes and starches (like those in alcohol). When the pancreas becomes irritated and inflamed, you can develop pancreatitis. Your liver produces enzymes that break down alcohol, but your liver can only handle so much alcohol at one time (approximately 1 ounce per hour). Seizures, hallucinations, and delirium may occur in severe cases of withdrawal. A weakened immune system has a harder time protecting you from germs and viruses.
Long-term alcohol use can affect bone density, leading to thinner bones and increasing your risk of fractures if you fall. A damaged pancreas can also prevent your body from producing enough insulin to use sugar. Some of these effects, like a relaxed mood or lowered inhibitions, might show up quickly after just one drink. Others, like loss of consciousness or slurred speech, may develop after a few drinks. Alcohol use can begin to take a toll on anyone’s physical and mental well-being over time. These effects may be more serious and more noticeable if you drink regularly and tend to have more than 1 or 2 drinks when you do.
