A hangover, medically known as veisalgia, is caused due to the consumption of large amounts of alcohol or some other drug. Hangover is most commonly associated with the after-effects of large consumption of alcohol. This article summarizes the cures and remedies available for alcohol hangovers.
The root cause of all hangovers is, of course, drinking alcohol. If you drink enough and end up with a hangover, it means you've ingested more alcohol than your body can metabolize efficiently. The toxins in alcohol build up in your body and make you feel sick. A chief culprit is a chemical called acetaldehyde. This is an alcohol by-product that research suggests may cause the worst of your hangover symptoms.
Hangover causes include dehydration, low blood sugar, the chemical by-products that alcohol leaves in your system, and depletion of vitamins and minerals. Alcohol is a diuretic. This means that it causes the body to lose water. This problem is made worse by the fact that when people are drinking alcohol, they seldom stop to have a glass of water. This loss of fluids causes dehydration. When your body doesn't have enough water to function properly, you'll experience symptoms of dehydration such as headache, dry mouth, and terrible thirst.
Hangovers are a combination of symptoms - headache, nausea, shakes, feeling very tired. The headache and the nausea can be caused by dehydration, or from the metabolic products of alcohol, which are toxic to the body and take time to be eliminated. Nausea can also be caused by alcoholic gastritis, an irritation of the stomach lining from alcohol consumption. The shakes are actually from alcohol withdrawal, as your body rids itself of the stuff.
Hangovers are multi-causal. Ethanol has a dehydrating effect by causing increased urine production (such substances are known as diuretics), which causes headaches, dry mouth, and lethargy. Dehydration causes the brain to shrink away from the skull slightly. This can be mitigated by drinking water or an oral electrolyte solution after consumption of alcohol. Alcohol's effect on the stomach lining can account for nausea. Because of the increased NADH production during metabolism of ethanol by the enzymes alcohol dehydrogenase and aldehyde dehydrogenase, excess NADH can build up and slow down gluconeogenesis in the liver, thus causing hypoglycemia.
Yes. A hangover can be prevented by abstaining from drinking alcohol. However, if you do drink alchohol, a hangover can be prevented by not drinking too much, not mixing different types of alcoholic drinks, and drinking plenty of water afterwards. Eating a meal before you drink will also help you avoid a hangover. When you have food in your stomach it slows the absorption of alcohol by your body.
