how long does it take to get an empty stomach
Consumer Reports News: October 22, 2009 10:34 AM. When the instructions say to take medicine on an empty stomach, how long do I have to wait after eating for my stomach to empty? Can I still drink while waiting? âW.H., Colorado Springs, Colo. For some medicines, having food or liquids in your stomach can result in poorer absorption of the drug or an upset stomach. It generally takes 4 to 5 hours for the stomach to empty after a full meal and a bit less after a snack or liquid, though it varies depending on how much and what kind of food you ate. If you can, itâs easiest to take empty stomach medications in the morning, after youâve fasted overnight. After taking the drug, wait at least 30 minute before ingesting anything other than plain water, to give the body time to absorb the medication.
