Huikan verran lisää infoa. Kovin rasvaisen aterian sulaminen voi kestää ad kuusi tuntia ennen kuin se etenee ohutsuoleen ja imeytyy sieltä. Siksi alkoholikin imeytyy siellä seassa hitaasti, koska se ei pääse ohutsuoleen, vaan sekoittuu ruoan joukkoon. 75 % imeytymisestä tapahtuu vasta ohutsuolessa.

Alkoholi alkaa imeytyä vereen jo suuontelossa. Noin 25 % nautitusta alkoholimäärästä imeytyy mahalaukusta. Suurin osa alkoholista kulkeutuu kuitenkin eteenpäin suolistoon. Varsinainen imeytyminen verenkiertoon tapahtuu ohutsuolen alkuosassa. Ohutsuolta ympäröivien verisuonten ja porttilaskimon kautta alkoholi päätyy maksaan ja sieltä edelleen muualle elimistöön.
Alkoholi kulkeutuu suolistosta ympäröiviin verisuoniin diffuusion avulla yhtä nopeasti kuin vesi. Imeytymisnopeuteen vaikuttaa alkoholijuoman väkevyys. Väkevä juoma lisää veren alkoholipitoisuutta nopeammin kuin vastaavan alkoholimäärän sisältävä laimeampi juoma. Nautittu ravinto hidastaa imeytymistä. Tämä johtuu nautitun alkoholin laimenemisesta ja mahalaukun tyhjentymisen hidastumisesta.
The rate at which people metabolize alcohol and the psychological effect varies from person to person depending on many factors. Here are some of those factors:
-
The amount of alcohol you drink.
-
The pace at which you consume the alcohol. The quicker you drink the higher your peak BAC will be. The liver gets rid of alcohol at the average rate of one drink per hour (12-oz. beer, 5-oz. wine, 1 shot of distilled liquor). If a person drinks faster than this, the remainder will circulate in the blood stream until the liver can get rid of it.
-
Body weight. Heavier people will be less affected by the same amount of alcohol than lighter people. They have more blood and water in their bodies in which to dilute the alcohol.
-
Food in the stomach. When there is food in the stomach, alcohol is absorbed slower into the blood stream. The BAC rises more rapidly in those who drink on an empty stomach because there is no food in which to dilute the alcohol.
-
The type of alcohol you drink.The stronger a drink is (the higher the alcohol concentration -
distilled alcohol first, wine second, beer third) the more quickly it is absorbed. This partially explains why hard liquor has more of an apparent "kick" than wine or beer.
-
Type of mixer used. Water and fruit juices mixed with alcohol slow the absorption process, carbonated beverages will speed it up.
-
Your physical and psychological condition - you are more likely to get drunk quicker if you are tired, stressed, sick, or angry.
-
Carbon dioxide (carbonation) speeds the alcohol through the stomach and intestine into the bloodstream, creating a rapid rise in BAC.
-
Temperature of the drink. Warm alcohol is absorbed quicker than cold alcohol. However, very cold, carbonated drinks are quickly absorbed.
-
If you are male or female. Women reach higher BAC’s faster because they have less water in their bodies and more adipose tissue (fat), which is not easily penetrated by alcohol. Therefore, a man and woman, with all other factors being equal, both drinking the same amount of alcohol will have different BAC levels. Hers will be higher.
-
A woman’s menstrual cycle will also affect her rate of absorption.
Women will experience their highest BAC’s premenstrually. In addition, there is also evidence that women taking
birth control pills, will absorb alcohol faster, resulting in higher BAC levels.
