San Francisco DUI Attorneys Explain Alcohol Absorption

Alcohol and Car Key About Alcohol Absorption

The chemistry between the absorption, distribution and elimination of alcohol is complex. It also varies from one person to the next. A variety of factors affect how much this varies, including genetics, gender, ethnicity, body composition, food consumption and liver volume. However, some of the degree of variance is based on the nature of the alcohol that different people consume.


San Francisco DUI attorneys know that how your system absorbs alcohol depends on a number of factors. This includes your individual drinking patterns, alcohol concentration in the beverages you drink, the form of dosage, how much food is in your stomach, and the time of day.


The quantity and nature of the food that is in your digestive system has the most direct effect on alcohol absorption. Should you consume alcohol on an empty stomach, you could be affected from anywhere between 15 minutes to two and a half hours. A moderate amount of food in one’s stomach usually means the alcohol absorption rate will take longer – as long as three hours. Consuming alcohol on a full stomach may mean it will take up to six hours for the alcohol to be absorbed. Food in the stomach acts essentially like a sponge for alcohol. It prolongs the alcohol’s course through the digestive system. What this means for DUI defendants is that there is a lower peak concentration and an increased amount of time for a person to reach the peak BAC level after having consumed food close to the time of consuming alcohol. This also means that, if you consume alcohol on an empty stomach, you will have a lower alcohol metabolism than someone who has food in his stomach at the time of consumption.
