How long does it take for a milkshake to go through your system I ate two milkshakes at 8 last night and am getting my glucose level tested at 1 today?

On average, it takes about 2 to 4 hours for food, including a milkshake, to pass through the stomach and enter the small intestine. However, the complete digestion and absorption process can take longer, typically around 24-72 hours for the entire system. By 1 PM today, your body will likely still be processing the milkshakes, which could affect your glucose level test, depending on your metabolism and the ingredients in the shakes. It's advisable to inform your healthcare provider about what you consumed prior to the test.
