What causes a hangover

hangovers explained

It’s no secret that drinking too much alcohol can cause a hangover. Have you ever wondered what goes on inside your body that could cause so much suffering? The facts are intriguing, and may even change how much you drink.

The formal term for hangover is veisalgia, from kveis, the Norwegian word for “uneasiness following debauchery,” and algia, the Greek word for pain. Generally, the more drinks consumed, the worse the hangover. Some common symptoms of hangover include:

  • General malaise
  • Headache
  • Nausea
  • Fatigue
  • Dehydration
  • Anxiety
  • Difficulty Sleeping

While we don’t know why all the symptoms of hangover occur, scientists have uncovered some unique facts behind the physiology of the common symptoms.

Vasopressin Inhibition: Enter Dehydration

Alcohol consumption blocks the production of vasopressin, a hormone that promotes water absorption in the body. Without enough vasopressin, the body sends water directly to the kidneys for elimination. Ever notice how much you run to the restroom when you’re out for drinks? Studies have shown that drinking about 250ml of an alcoholic beverage causes the body to expel 800 to 1000ml of water; a four-to-one loss!

This diuretic effect helps create the fatigue and dry mouth. And that headache? During dehydration, the body’s organs compensate by stealing water from the brain, causing it to reduce in size and pull on the membranes connecting it to the skull. Ouch!

Frequent urination also depletes the body of magnesium and potassium, critical for proper muscle and nerve function, a lack of which can lead to headaches, fatigue and nausea.

Glycogen Breakdown

Alcohol breaks down the body’s store of glycogen, a key energy source, turning it into glucose that gets expelled in the urine. The resulting lack of glycogen is partly responsible for the weakness, fatigue, and lack of coordination you feel the next day.

The amount of alcohol consumed isn’t the only factor; what kind of alcohol you drink affects you, too. Alcohol contains congeners, toxic byproducts of fermentation. The greatest amounts are found in red wine and dark liquors such as bourbon, brandy, and whiskey, while less is found in clear liquors such as vodka and gin. White wine has the least. Combining different kinds of alcohol compounds the toxic effect. Finally, the carbonation in beer speeds up alcohol absorption; following beer with liquor puts extra strain on the liver to deal with the added toxins, hence the phrase, “Beer before liquor; never sicker.”

Glutathione: Your Hangover Prevention Ally

A product of alcohol that is more toxic than alcohol itself, acetaldehyde, is created when liver breaks down alcohol. The body attacks it with a powerful antioxidant called glutathione. When we drink in moderation, the levels of glutathione in the liver can keep up with the need for detoxification; we feel fine the next day. When we drink too much, the liver’s store of glutathione depletes quickly, allowing toxic acetaldehyde to build.

Glutathione is our body’s most powerful antioxidant; this enzyme is integral for regulating the immune system, and is on the front line of fighting destruction from oxidative stress in the body. You need it to function well. When glutathione is depleted, it sets the stage for destructive inflammatory processes; in fact, studies show a direct correlation between a breakdown in the glutathione system and autoimmune disease.

Glutamine Rebound

The fatigue, stomach irritation, and general malaise that hangovers deliver have been tracked to glutamine rebound. While you drink, alcohol inhibits glutamine, one of the body’s natural stimulants. When you stop drinking, the body responds by producing more than it needs. The increased glutamine stimulates the brain, preventing deep, refreshing levels of sleep, which results in fatigue the next day. Severe glutamine rebound may also be responsible for hangover tremors, anxiety, restlessness, and increased blood pressure.

Alcohol Contributes to Leaky Gut

Alcohol can contribute in a variety ways to leaky gut, a condition where the lining of the intestinal tract becomes over-permeable, allowing foreign particles into the bloodstream and promoting inflammation throughout the body.

For instance, alcohol reduces the body’s production of prostaglandins, substances that help control inflammation. Suppression of prostaglandins allows systemic inflammation to increase, which can trigger or contribute to leaky gut.

Heavy alcohol consumption also damages the lining of the gastrointestinal tract, reducing the body’s ability to extract nutrients from food. This can lead to micronutrient deficiencies that help drive various chronic disease states.

As you can see, excessive alcohol consumption has some pretty serious effects on the body; our casual cultural mindset about the consequences –- a hangover –- gloss over the ugly truth of what happens inside the body when we over-consume alcohol.

New study pegs sugar as main culprit in diabetes

sugar and diabetes

For years, medicine has pegged obesity as the number one cause of diabetes. However, results of a recent large epidemiological study suggest it’s sugar that plays a pivotal role in diabetes. The study also illustrates that how many calories you eat isn’t as important as what makes up those calories — the study found calories from sugar is more damaging than calories from other foods.

Researchers looked at the correlation between sugar availability and diabetes in 175 countries during the last ten years and controlled for such factors as obesity, calories consumed, diet, economic development, activity level, urbanization, tobacco and alcohol use, and aging.

They found the more sugar a population ate the higher the incidence of diabetes, independent of obesity rates. According to Sanjay Basu, MD, PhD, the study’s lead author, “We’re not diminishing the importance of obesity at all, but these data suggest…additional factors contribute to diabetes risk besides obesity and total calorie intake, and that sugar appears to play a prominent role.” The study provides the first large-scale, population-based evidence for the idea that perhaps it’s not just calories, but the type of calories, that matter when looking at diabetes risk.

All calories are not created equal

One thing is clear from the study – although by definition all calories give off the same amount of energy when burned, sugar is uniquely damaging to the body.

The study showed an additional 150 calories from any food source caused a 0.1 percent increase in the population’s diabetes rate whereas an additional 150 calories of sugar caused it to raise a full 1 percent. That’s a ten-fold increase. To put it into perspective, a can of soda contains roughly 150 calories of sugar. Consider the average American consumes 22 teaspoons of added sugar a day, or about 350 calories’ worth, and it’s clear why diabetes is the fastest growing disease in history.

The study also showed the longer a population was exposed to excess sugar, the higher the diabetes rates were. The clincher: Diabetes rates dropped when sugar availability dropped, independent of changes in calorie intake, physical activity, or obesity rates.

Does sugar cause diabetes?

Does sugar cause diabetes? It’s too early to say definitively, but this study clearly shows a correlation and spotlights the need for more research. Dr. Basu suggested sugar affects the liver and pancreas in ways that need more exploration.

What can you do to prevent or manage diabetes?

While there are various forms of diabetes, Type II diabetes, which is caused by diet and lifestyle, accounts for 90 percent of all cases of diabetes.

What can you do to minimize your risk for diabetes? Reducing your sugar intake is a great place to start. In functional medicine we understand that every body is unique. We start with a careful evaluation of your health history, lifestyle, heredity, nutritional status, and environmental risk factors. We help you customize a program that includes diet, exercise, stress management, nutritional support, detoxification, gut health support, and dampening of inflammation — all of which can dramatically affect your insulin and blood sugar levels and hence your risk of diabetes. This can reverse the path to diabetes and sometimes even the disease itself.
