How long does it usually take for a full recovery from chronic cholecystitis surgery and what are some things a person should keep in mind during the recovery period? I believe the overproduction of CCK is a large component of why lectins are bad for lectin sensitivepeople. Trypsinis an enzyme releasedby the pancreas that reduces CCK by breaking down the enzyme that causes CCK to be released (CCK-releasing enzyme and monitor peptide) [8]. Cholecystokinin is not directly involved in any medical treatment to date, but it has been used in drug development and testing.
