Alcohol Absorption & Elimination

Kansas City DUI Lawyer Providing Aggressive Defense

Were you arrested for an alleged DUI offense because chemical tests showed that you had a blood alcohol concentration (BAC) of 0.08% of above? If so, you should have an attorney help you determine whether certain factors related to your body's rate of alcohol absorption and elimination could make a difference in your case. When a person consumes alcohol, that alcohol is absorbed within the stomach and the small intestine (though mainly the small intestine), according to educational resources provided on the National Institute of Health website. Next comes the elimination phase. In this phase, most of the alcohol is metabolized in the liver. The part that is not metabolized (usually less than 10%) leaves the body (or is excreted) through sweat, urine and breath. Concentrations of alcohol in breath and urine are seen as reflections of the concentration of alcohol in the blood, which is why breath tests and urine tests can be used in addition to blood tests to determine a person's BAC level. However, breath tests can be highly inaccurate and urine tests are almost always very poor tests for alcohol.

At Paul W. Burmaster P.A., our skilled Kansas City DUI attorney can help you determine whether any of these influencing factors are present in your case. If they are, we may be able to use this information to help you contest your DUI charges!

Factors Affecting Absorption and Elimination

A bell curve is often used to illustrate the process of absorption and elimination in the body. Once a person consumes and alcoholic beverage, the individual's BAC rises sharply and hits its peak while it is in the absorption phase. Although this usually occurs within about 45 to 90 minutes following alcohol consumption, there are certain circumstances that can make this time shorter or longer. While the alcohol is being distributed throughout the body, the BAC drops sharply. During the elimination stage, the BAC declines at a slower rate.

It is important to remember that everyone is different. There are certain aspects of a person's physiology and specific circumstances that could impact the rate of absorption and elimination. This includes the following:

  • The person's weight
  • Whether the person had food in his or her stomach
  • What type of food was consumed
  • Diabetes or other illnesses
  • The type of drinks and duration consumed

There tends to be an amount of time that passes from when a person is actually driving to when he or she is given a BAC test. When analyzing BAC test results, it is important to factor in the timing of the test, whether the driver was in the absorption stage at the time, and whether he or she was likely to have a faster or slower absorption process and elimination process. When these factors are not properly considered, a person can be accused of having the wrong BAC while driving, which can potentially result in a wrongful conviction.
