The older someone is, the more worn their organs become including the liver, which is responsible for removing 90 percent of alcohol from the body. WeightThe more someone weighs the more alcohol it will take to increase their blood alcohol levels. However, being overweight may not affect alcohol levels in the body because alcohol is not very fat-soluble. GenderMen tend to have more lean tissue mass, which equates to a higher tolerance to alcohol. Men also have more of the enzyme responsible for breaking down alcohol in their stomach. Women are typically built smaller and have a lower tolerance to alcohol because of it. MedicationsConsuming other medications can impact how long alcohol stays in the blood. The body sees alcohol like a toxin that needs to be removed. Taking other medicines in addition to alcohol can confuse the body’s systems on which substance to extract first. In some cases, the liver will only have the capacity to process the other medication, and removing alcohol will come later. Food ConsumptionEating before consuming alcohol can influence how much alcohol is absorbed by the body at once. This can slow the ingestion of alcohol, causing it to stay in your system longer. The reverse is also true. When drinking on an empty stomach, alcohol is absorbed more quickly. Though this doesn’t speed up how long alcohol stays in your blood, the faster it is absorbed, the quicker the liver can process it.

Most healthy people circulate blood throughout their bodies in about 90 seconds, which allows alcohol to reach the brain and other organs in a short time. The full effects of alcohol are typically felt 15 to 45 minutes after consumption, depending on the speed of absorption.
