Can medical conditions affect Breathalyzer tests?

On Behalf of | Oct 11, 2021 | Criminal Defense |

Driving privileges are extremely important to many people across North Carolina. Not only does traveling on the roads allow employees to make it to work, but it can also facilitate family visits and leisure activities.

As a result, receiving a conviction for a DUI offense can have lasting consequences. One key piece of evidence that will likely be used in a DUI case is the breathalyzer test. However, it is important to remember that Breathalyzer tests are not always accurate. Several factors can influence test results and lead to them giving inaccurate impressions. One aspect that may impact the results of a chemical test is medical conditions.

Acid reflux

If you are suffering from acid reflux, it is possible that alcohol could rise from your stomach into your esophagus. This may result in a Breathalyzer test showing that you have a heightened blood alcohol content.

Liver or kidney disease  

Suffering from liver or kidney disease could mean that your organs are not functioning as they should. Consequently, your blood might not be filtered in the same way as a healthier person. Ultimately, this could lead to a test result that is skewed.


One symptom of diabetes is that you may have higher levels of acetone on your breath, which could ultimately lead to higher results on a chemical test. Additionally, common symptoms of diabetes can include dizziness and confusion, which on top of test results, could give the false impression that you are under the influence.

Understanding medical conditions that could potentially impact a Breathalyzer test may be in your best interests. As a road user in North Carolina, it may benefit you to know what legal rights you have.
