I am frequently asked what the transit time is from when the food is ingested to when the stomach empties. The emptying of the stomach depends on a number of complex factors, including the function of the pylorus, the type of food ingested, and a number of known and possibly unknown regulatory hormones.

In a previously published newsletter, we already discussed a number of hormones that play a role in the regulatory function of the GI track. The detailed information is posted in the newsletter section of our website.
