The myth that moderate drinking is good for your heart takes a blow from this new study, which suggests the United States alcohol guidelines are too…. Alcohol has short-term and long-term effects. Drinking a small amount can help people feel relaxed, but too much, too often, can be harmful for health.

Drinking alcohol disrupts the fine balance of our oral bacteria, a new study shows. Thus, harmful types are fostered over helpful ones, promoting…. Earlier studies conclude that drinking alcohol in moderation might be healthier than abstaining. A new study, however, overturns this theory. How the body processes alcohol. Medically reviewed by Timothy J. Legg, Ph. How does the body process alcohol? What affects the rate that alcohol is processed? How long does alcohol stay in the system?

What are the long-term risks of drinking? Takeaway A big concern that many people have is how long the alcohol they have been drinking will remain in their system. Share on Pinterest The effects of a high blood alcohol concentration may include impaired memory, confusion, slurred speech, and nausea. Share on Pinterest Blood flow may be slower in older people, so alcohol may stay in the system for longer. Asian descent Some people of Asian descent have more difficulty metabolizing alcohol.

Family History First-degree relatives children, siblings or parents of alcoholics have been estimated to have a seven times greater chance of developing alcoholism. What is the difference between a blackout and passing out?

What is a hangover and can I prevent it? The only way to prevent a hangover is to drink in moderation: Eat a good dinner and continue to snack throughout the night.

Alternate one alcoholic drink with one non-alcoholic drink. Avoid drinking games or shots. Drinking a large amount of alcohol in a short amount of time is the most likely way to become dangerously intoxicated. This simply puts more alcohol in your body and prolongs the effects of the alcohol intoxication.

Having caffeine while drinking will not counteract the intoxication of alcohol; you simply get a more alert drunk person. Excessive caffeine will continue to lower your blood sugar and dehydrate you even more than alcohol alone. Giving water to someone who is throwing up. Once the stomach is irritated enough to cause vomiting, it doesn't matter what you put into it -- it's going to come back up.

Any liquid will cause a spasm reaction and more vomiting. It's best not to take a pain reliever before going to bed. Give your body a chance to process the alcohol before taking any medication. Processing alcohol causes a drop in blood sugar and can contribute to headaches. Drink plenty of water and juice to get rehydrated. Take a pain reliever, such as ibuprofen or acetaminophen when you wake up. Let your body process the alcohol while you are sleeping.

We do not recommend aspirin because of Reyes syndrome, a rare but serious illness in teenagers and children. Avoid excessive caffeine as it may contribute to dehydration. However, if you drink coffee every morning, have your first cup not more than a couple of hours after your regular time.

An over-the-counter antacid Tums, Pepto Bismol or Maalox may relieve some of the symptoms of an upset stomach. Do not go too many hours without food as this will increase the effect of the low blood sugar caused by alcohol. When alcohol is consumed, it enters the stomach, where it can be absorbed into the bloodstream.

However, if no food is present, most of the alcohol moves down into the small intestine where there is a much larger surface area for absorption compared to the stomach. The cells that line the stomach and small intestine part of the gastrointestinal or GI tract are called epithelial cells.

These cells are perfect for absorption because they have finger-like projections protruding into the GI lumen , which tremendously increases the surface area for absorption of nutrients and other molecules through the membranes.

If one drinks alcohol with food in the stomach, the pyloric sphincter separating the stomach from the small intestine closes to allow the food to be digested by stomach acid. To be absorbed, alcohol moves across the epithelial cells, through the interstitial space, and into the capillaries.

The capillaries are made of endothelial cells. As alcohol moves through each of these cells, it moves in the direction of the concentration gradient. Figure 1. Ethanol molecules in the gut diffuse across epithelial cells, through the interstitial space, and then into nearby capillaries.

The movement of alcohol across cell membranes is possible because of its chemical character and the biophysical properties of the membrane. The cell membrane is a lipid bilayer—it contains phospholipids, small molecules that have a polar phosphate head hydrophilic or water loving and a nonpolar lipid tail hydrophobic or water fearing Figure 1. Two layers or sheets of phospholipids are stacked together with their lipid tails touching to form a hydrophobic core.

The polar phosphate heads face the water-filled exterior or interior of the cell.
