Alcohol’s health effects on the body: Risks of drinking, explained

She often brings her own nonalcoholic beer or wine to social gatherings, Laing said, and most bartenders are happy to make a mocktail. Perhaps the most common myth about the benefits of alcohol is the idea that an occasional glass of red wine boosts heart health. Tolerance and dependence can both happen as symptoms of alcohol use disorder, a mental health condition previously referred to as alcoholism, that happens when your body becomes dependent on alcohol. This condition can be mild, moderate, or severe, depending on the number of symptoms you have. People who binge drink or drink heavily may notice more health effects sooner, but alcohol also poses some risks for people who drink in moderation. And perhaps that should not be too surprising since study methods differ widely.

The risks of drinking too much

The pancreas helps regulate how your body uses insulin and responds to glucose. If your pancreas and liver don’t function properly due to pancreatitis or liver disease, you could experience low blood sugar, or hypoglycemia. 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. Since those effects don’t last long, you might not worry much about them, especially if you don’t drink often. By working together effectively, the negative health and social consequences of alcohol can be reduced. A variety of factors which affect the levels and patterns of alcohol consumption and the magnitude of alcohol-related problems in populations have been identified at individual and societal levels.

When should you cut down on drinking?

1. Drinking small amounts — especially of red wine — is linked to various health benefits.
2. “I drink three or four times a week and I have one or one-and-a-half glasses of wine. I’m not concerned that’s adversely affecting my health.”
3. Alcohol abuse during pregnancy is the leading preventable cause of birth defects in the US.

Binge drinking is behavior that raises blood alcohol levels to 0.08%. That usually means four or more drinks within two hours for women and five or more drinks within two hours for men. Moderate drinking is defined as no more than one standard drink per day for women and no more than two for men. Recommendations for alcohol intake are usually based on the number of standard drinks per day. Numerous factors can predispose people to problematic drinking, such as family history, social environment, mental health and genetics. Simultaneously, alcohol abuse is the third main cause of preventable death in the US, as it’s a large factor in chronic diseases, accidents, traffic crashes and social problems (68).

What’s considered binge drinking?

However, when it comes to heavy drinking and binge drinking, your risk rises (53, 54, 55, 56). For example, light to moderate drinking is linked to reduced have a problem with alcohol weight gain, whereas heavy drinking is linked to increased weight gain (32, 33, 34). Consuming moderate amounts of alcohol may offer some health benefits.

Risks of heavy alcohol use

The paper is only in pre-print and still needs to be peer-reviewed, but for now, its authors came to similar conclusions as the Lancet study, even though they used a different set of data. The researchers also estimated that men who halved their alcohol consumption — from about 14 drinks per week to about seven — might gain one to two years in life expectancy. In April, a big meta-study involving 600,000 participants, published in April in the Lancet, suggested that levels of alcohol previously thought alcohol and accutane to be relatively harmless are linked with an earlier death. What’s more, drinking small amounts of alcohol may not carry all the long-touted protective effects on the cardiovascular system. Experts in alcohol-related diseases don’t want to stop people from having fun, but they often come down on the side of “less is better” and any alcohol at all carries some risk. Others, mostly those who focus on population-level data for their research, say there’s still a benefit to moderate drinking.

Having a glass of wine with dinner or a beer at a party here and there isn’t going to destroy your gut. But even low amounts of daily drinking and prolonged and heavy use of alcohol drugs brains and behavior can lead to significant problems for your digestive system. Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day.

For someone with an alcohol use problem, the only safe level of drinking is none, Streem said. Someone with a family history of alcohol use disorder also should avoid all alcohol. Heavy drinking also costs the public money, David Jernigan, a Boston University School of Public Health professor of health law, policy and management, recently told Massachusetts legislators. In 2010, the most recent data available, problem drinking cost the state government $345 per person, he said, while alcohol taxes generated only $11. George Koob, who directs the National Institute on Alcohol Abuse and Alcoholism, also stands by the American guidelines, though he notes they are currently under review. More and more studies, he said, show that drinking even a small amount increases the risk for cancer, and 5% of cancers are causes by alcohol.

Each of those consequences can cause turmoil that can negatively affect your long-term emotional health. If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink. That’s because alcohol can weaken your immune system, slow healing and make your body more susceptible to infection. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general.

Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors. In the United States, people younger than age 21 are not legally able to drink alcohol. If you tend to drink excessively or notice that alcohol causes problems in your life, you should avoid it as much as possible. In the US, one standard drink is any drink that contains 0.6 fluid ounces (14 grams) of pure alcohol (ethanol). The problem is, most people have no idea what qualifies as a “standard drink.” To worsen matters, the official definition of a standard drink differs between countries.

In the past, moderate drinking was thought to be linked with a lower risk of dying from heart disease and possibly diabetes. After more analysis of the research, that doesn’t seem to be the case. In general, a healthy diet and physical activity have much greater health benefits than alcohol and have been more extensively studied. Light to moderate drinking is linked to a reduced risk of heart disease, while heavy drinking appears to increase the risk (37, 38, 39, 40).
