How does gastric bypass affect time released medication?

If you have had a Gastric Bypass you can no longer take time released medications & you should point that fact out to any health care professionals whom you see for the rest of your life. Time released medications need to stay in your stomach for hours to work all the way....because of the reduction & reconfiguration of your stomach medication does not stay there long enough to fully dissolve or "time release"....it moves on to the intestine before it has had a chance to do what it was supposed to do.
