For some people, alcohol can disrupt activity in an area of the brain called the amygdala, which is involved in mediating emotions. Over time, toxic damage from chronic alcohol use will affect a person’s executive function. It can also affect a person’s ability to make decisions and their self-control.

Your liver detoxifies and removes alcohol from your blood through drinking too much alcohol can harm your health learn the facts a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide. Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body. More information about alcohol and cancer risk is available in the Surgeon General’s advisory.
When you drink too much alcohol, it can throw off the balance of good and bad bacteria in your gut. Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion. They also help fend off inflammation and support healthy metabolism. That’s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats. So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work.
Alcohol also impairs working memory, making it harder to keep track of details, follow instructions, and complete complex tasks that require ongoing mental processing. Alcohol slows signals from the brain to the muscles responsible for the coordination and control of muscles involved in speech, leading to a noticeable slowing down or slurring of words when intoxicated. “Alcohol interferes with the brain’s communication pathways, and can affect the way the brain looks and works,” says the NIAAA. “These disruptions can change mood and behavior, and make it harder to think clearly and move with coordination,” they say. Alcohol can impact the gut microbiome—a complex ecosystem of bacteria that lives in the digestive tract and shapes our greater health. If you know an older person who you suspect is overusing alcohol, you may want to speak with them about your concerns for their well-being.
Consuming alcohol during menopause can also increase the risk of heart disease and osteoporosis, says Dr. Jewel M. Kling, M.D., M.P.H., a physician with Mayo Clinic Women’s Health in Arizona.

- It can be attempted by regulating and limiting the sale of alcohol , taxing alcohol to increase its cost, and providing education and treatment.
- This means pacing yourself, eating before drinking, knowing your limits, and avoiding excessive consumption.
- However, if this proves difficult, Volpicelli recommends exploring online and in-person peer support groups like AA or SMART Recovery, which can help individuals address problem drinking behavior.

Past guidance around alcohol use generally suggests a daily drink poses little risk of negative health effects — and might even offer a few health benefits. If you drink, you’ve probably had some experience with alcohol’s effects, from the warm buzz that kicks in quickly to the not-so-pleasant wine headache, or the hangover that shows up the next morning.
