Yes, alcohol affects hormones in women by increasing estrogen and cortisol, and decreasing progesterone, which can lead to issues like irregular menstrual cycles, worsened menopause symptoms, and an increased risk for certain health conditions. The liver prioritizes metabolizing alcohol, disrupting the body’s normal hormone regulation, and its effects are seen across all stages of a woman’s life.

Heavy alcohol consumption may lead to earlier and more severe brain bleeds, according to a study published by researchers at Massachusetts General Brigham earlier this month.
Using data from patients admitted to MGB between 2003 and 2019 who had brain bleeds, the researchers found that people who drank heavily — defined as three or more alcoholic drinks a day — were 11 years younger, on average, when their bleeds occurred.
Strokes can be categorized into two types: ischemic strokes, which occur when blood flow to the brain is blocked, and hemorrhagic strokes, which result from a ruptured blood vessel. The researchers focused on the latter, which typically lead to more severe damage.
“Hemhorrhagic strokes, or brain bleeds, are less common, but they are a lot more dangerous,” said Edip Gurol, an associate professor of neurology at Harvard Medical School and author of the study. “50 percent of people who have a brain bleed die within the first month.”
The study, published in Neurology, tracked 1,600 patients over the course of 16 years, of which seven percent reported heavy alcohol consumption. The median age of brain bleeds for heavy drinkers was 64, compared to 75 in those who did not report heavy alcohol consumption.
“There was a very, very significant difference, which is telling us that one way or the other, heavy drinking is accelerating the brain bleeds,” Gurol said.
Using CT scans to determine the size and location of bleeds, the authors found that heavy drinkers experienced 70 percent larger bleeds and were twice as likely to have a bleed deep inside their brain.
“The brain bleeds in those patients were more likely to be deep and more likely to open inside the spinal fluid-filled spaces, the ventricles of the brain,” Gurol said.
Patients who reported heavy alcohol usage had higher blood pressure and lower blood platelet counts when they were admitted to the hospital, the study found. Those patients also showed greater evidence of small vessel damage in the brain, which is linked to several other health conditions such as dementia and heart failure.
“Despite their younger age, very probably because of the excessive alcohol use, these people had more severe small vessel disease-related brain damage, which is called white matter disease,” Gurol said.
Alvin S. Das, an assistant professor at Beth Israel Deaconess Medical Center, said the finding that heavy drinkers experienced larger brain bleeds would prompt him to stress the importance of cutting back on alcohol to his patients.
“What it might compel me to do is in a patient that comes to my office and they’ve had a deep hemorrhage, not only counsel them on aggressive hypertension management down the road to prevent another hemorrhage, but this study also would push me to counsel alcohol cessation,” Das said.
Because the number of heavy drinkers in the study was small and the data came from a single hospital, the researchers noted that future work should use larger datasets to examine how varying levels of alcohol use affect brain aging and stroke risk.
Gurol, for his part, said the findings underscore the importance of limiting alcohol consumption broadly, even in individuals without pre-existing health conditions.
“Even for people without known risk of alcohol damage, it is probably best to not to exceed three glasses per week and not to exceed one glass in over 24 hours,” Gurol said.

How Long Does It Take to Detox From Alcohol?
Wondering if you need an alcohol detox? Learn how to detox your liver from alcohol use, and how long it could take.
Of all your body’s organs, your liver takes the biggest hit when it comes to alcohol. Even if your relationship with drinking consists of occasional social drinking with friends or occasionally over-indulging in wine and cocktails during the holiday season, alcohol can still leave its mark. And it’s a mark that can be hard to reverse.
That’s why many of us wonder if a month of avoiding drinking is enough to “reset” your liver back to normal. It’s true that taking a break from alcohol for any amount of time will be beneficial overall, with some research showing that liver function begins to improve in as little as two to three weeks. But a full detox is needed for the most benefit, and how much time that takes depends on a variety of personal factors.
“It depends on how much damage has already been done,” explains liver specialist Christina Lindenmeyer, MD. “And if there are any complications related to the damage.”
Dr. Lindenmeyer explains what happens to your liver from prolonged and moderate alcohol use, and what a detox process would look like.
Your liver has enzymes that work like special tools to help metabolize (break down) different toxins that enter your body, such as alcohol.
In the short term, alcohol is processed through your liver in about an hour. Essentially, feeling “drunk” is when your liver becomes too overwhelmed to properly process alcohol, so it overflows temporarily into your bloodstream. This is what causes you to feel light-headed or tipsy after multiple alcoholic drinks.
In the long term, prolonged alcohol use can cause severe damage to your liver. Your liver has a specific pathway that the toxins follow to be broken down, so if over time, this pathway becomes overwhelmed by too many toxins, it can affect the efficiency of your liver’s work. In other words: It can’t keep up.
Certain health concerns and diseases can arise in your liver due to long-term alcohol use, including:
If your liver has taken a hit from prolonged alcohol use, there are ways to give it — and the rest of your body — a break.
You can make the move toward detoxing your liver through these steps:
The first and most important line of defense? You guessed it: Abstain from drinking. “Abstinence is the most critical intervention and treatment,” notes Dr. Lindenmeyer.
This is sometimes easier said than done, of course. If you’re a heavy drinker, you may need to wean off alcohol to let your body adjust. If you’re experiencing severe symptoms of alcohol withdrawal, be sure to talk to a healthcare provider.
If you’re more of a moderate to occasional drinker, you may find the hardest part of stopping drinking to be the social pressures. Try replacing your usual cocktail or beer with a nonalcoholic option, including many of the now popular mocktails available so you can still enjoy social time with friends without having alcohol in the mix.
Another thing that will help your liver’s journey in recovery is good nutrition. There’s no miracle diet by any means, but the Mediterranean diet, for example, can help fill some of the nutritional gaps you may have due to alcohol use.
“Nutrition optimization is actually the most evidence-based and most important intervention aside from stopping drinking,” points out Dr. Lindenmeyer. This is because, for a lot of people who experience some kind of liver dysfunction, it makes them at risk of not getting enough proteins, calories or vitamins.
There are also certain foods like tea, fish and nuts that can benefit the liver’s function in many ways. Think of it as giving your liver a little boost in the right direction. “Nutrition therapy is very important in terms of feeding the liver and giving it the building blocks it needs to restore itself,” says Dr. Lindenmeyer.
Of course, we all want a simple, achievable number for how long we should abstain from alcohol in order for our bodies to fully heal from its effects.
But the truth is,the timeline of your liver detoxing is going to depend on different factors like:
“There is no ‘one size fits all’ answer,” states Dr. Lindenmeyer. “It depends on how much damage has already been done and any possible complications.”
There has been some research conducted on how abstaining from alcohol detoxifies your liver over time. A 2021 review of research notes that several studies determined that two to four weeks of abstinence from alcohol by heavy-alcohol users helped reduce inflammation and bring down elevated serum levels in the liver.
In short: A few weeks off will help. But the longer you can abstain from alcohol, the better. And if your liver has experienced long-term effects, your healthcare provider would probably recommend lifelong abstinence from alcohol to allow it to fully detox and recover.
“For patients who are left with cirrhosis after severe injury to the liver from alcohol, even one drink of alcohol is toxic to the liver,” cautions Dr. Lindenmeyer.
For many of us, alcohol becomes a casual routine associated with going out and spending time with loved ones. But if you’re drinking alcohol in excess of the recommended guidelines, you may be doing damage to your liver. It can be hard to notice at first if your body is sending you any warning signs that it’s overwhelmed.
Here are some common signs that your liver is taking a serious hit from alcohol:
It can be hard to find (or even know) the balance of how much alcohol your body is able to handle. If you’re not sure if your drinking crosses a certain line or not, try measuring your alcohol intake.
According to the U.S. Centers for Disease Control and Prevention (CDC), alcohol should be consumed in moderation, which means one drink a day for women and people assigned female at birth (AFAB), and two for men and people assigned male at birth (AMAB) — unless your doctor says otherwise. If you’re keeping up with this average (or less), the damage from alcohol is most likely minimal.
On the other hand, binge drinking is generally defined as four drinks for women and five drinks for men within a two-hour period. And even occasional binge drinking episodes can have profound effects on your liver’s health over time.
Overall, a small break from drinking like a Dry January won’t necessarily fully “detox” your liver, but if you’re prone to overindulging in alcohol, you can see small health boosts such as decreasing inflammation of the liver and increasing your energy levels with such a break.
Just like a broken bone or infection needs time to heal, so does an overworked liver. While this depends on the amount of alcohol you have had over the years, your liver can see partial healing within two to three weeks, but this will depend on your health history.
Depending on the extent of liver damage you have, you may need to completely abstain from alcohol in order to give your liver the best chance for recovery. Talk to a doctor about your personal history and what’s right for you.

Leading cause of death of those age 15-49
Stopping for happy hour with colleagues after work. Cracking open a cold beer (or two) while watching the game. Meeting up with girlfriends for a glass of pinot noir. Having an alcoholic beverage of choice is a common way to unwind. But according to a recent study, even casual drinking can put your long-term health at risk.
Liver specialist Jamile Wakim-Fleming, MD, did not take part in the study, but says the research found that alcohol was a leading risk factor for both disease and premature death.
“They found that alcohol was the seventh leading cause of death worldwide,” she says. “But even more alarming, is that it was the first leading cause of death of people between the ages of 15-49.”
The study looked at global data from hundreds of previous studies and found that for all ages, alcohol was associated with 2.8 million deaths each year.
Researchers found that alcohol-related cancer and heart disease, infectious diseases, intentional injury, traffic accidents and accidental injury were some of the leading causes of alcohol-related deaths.
Dr. Wakim-Fleming says people often believe that a little bit of alcohol, wine in particular, may be good for their heart. But the study results didn’t show any health benefit to drinking any amount of alcohol.
She says this information, along with previous research that has shown more young people are dying from alcohol-related liver disease, indicates that excessive drinking among young adults is a growing problem.
And like any substance-abuse problem, Dr. Wakim-Fleming says the damage to the body from alcohol increases over your lifespan.
“It’s a cumulative effect,” she explains. “If you do it all at once, then you’re going to have the effect now. If you drink on a regular basis, over years it’s going to be cumulative and you will end up with a problem later on.”
Dr. Wakim-Fleming notes that anything we do in life involves risk, but it’s important to know what the risks are so that we can make the best decisions for our health.

There are many health benefits related to abstaining from alcohol. If you’re looking to cut back or stop drinking altogether, here are 11 tips that can help. #HarvardHealth
Are you concerned about your alcohol intake? Maybe you feel that you’re drinking too much or too often. Perhaps it’s a habit you’d like to better control.
It’s always wise to check with your doctor — she should be able to help you decide whether it is best for you to cut back or to abstain. People who are dependent on alcohol, or have other medical or mental health problems, should stop drinking completely.
But many people may benefit simply by cutting back. If your doctor suggests that you curb your drinking, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) suggests that the following steps may be helpful:
